Tyler Keillor’s new tyrannosaurs

Paleoartist Tyler Keillor has not one but two new tyrannosaur sculptures on display in museums north of Chicago, and this past weekend I paid both of them a visit. Keillor has been reconstructing extinct animals since 2001, most frequently in collaboration with Paul Sereno. You may well have seen Keillor’s fleshed models of Rugops, Kaprosuchus, Eodromaeus, and others, all commissioned by Sereno to accompany press releases announcing new discoveries. Keillor also specializes in restoring incomplete fossil material, assembling physical or digital models of the complete, undamaged bones. The composite Spinosaurus skeleton from the 2014 National Geographic traveling exhibit was his work, as is the skull on the mounted skeleton of Jane the juvenile Tyrannosaurus at the Burpee Museum of Natural History.

Tyler Keillor’s Dryptosaurus at the Bess Bower Dunn Museum.

One of Keillor’s latest and most ambitious pieces debuted on March  24th at the brand-new Bess Bower Dunn Museum in Libertyville, Illinois. Standing at the entrance to the museum’s galleries, the life-sized Dryptosaurus is a show-stopping centerpiece. Never mind that no dinosaur fossils have been found in Illinois –  Dryptosaurus lived on the other side of the Cretaceous continent of Appalachia, which is as good an excuse as any to include a giant model dinosaur.

During the very well-attended opening event, Keillor gave a standing-room-only talk about creating the model. Dryptosaurus is only known from a handful of fossils, the most complete parts being the arm and leg. Working with Richard Kissel, who served as the project’s scientific advisor, Keillor had to make a number of educated choices to turn the available fossil material into a 20-foot fleshed model. The shape of the head, for example, is based on that of Jane, while the tiny, millimeter-sized scales are informed by recently published skin impressions of various tyrannosaurs. Less certain is the choice to give Dryptosaurus a two-fingered hand. For the time being, the three-fingered skeletons Research Casting International built for the New Jersey State Museum are no less reasonable.

Opening day at the Dunn Museum was mobbed – it’s great to see so many people excited about a new museum!

Keillor’s 2009 Dryptosaurus head is meant to be a male, while the new sculpture represents a female.

During the planning stages, Keillor prepared three possible poses for the museum to pick from. The Dryptosaurus could be standing tall, leaning forward with its mouth open, or crouching down next to a nest mound. Keillor favored the nesting pose, both because it was unusual and because the Dryptosaurus holotype fossils may have come from an animal that had recently laid eggs*. Unsurprisingly, museum staff opted for the more spectacular open-mouthed version.

The bulk of the model is foam, created on a milling machine using data from a digital model produced by Keillor. The foam body form is covered with nearly 200 pounds of epoxy putty, applied and textured by hand. Keillor casted the head as a separate piece, using the molds from a standalone Dryptosaurus head he produced for the Dunn Museum’s predecessor in 2009. The patches of fluff are made from a commercially-available synthetic fiber that resembles kiwi feathers.

*Edward Cope noted in the 1880s that the Dryptosaurus limb bones had large, hollow medullary cavities. Gravid female birds grow extra layers of bone in their medullary cavities to stockpile calcium, which they use to produce eggshells. We now know that several non-avian dinosaur species did the same. 

Little Clint at the Dinosaur Discovery Museum.

Keillor’s other new model is “Little Clint” the infant Tyrannosaurus rex, which debuted at the Dinosaur Discovery Museum in Kenosha, Wisconsin with absolutely no fanfare. The model is part of a new exhibit all about the discovery and interpretation of the pocket-sized T. rex fossils it’s based on. Frustratingly, there’s no mention of the exhibit on the museum’s website, and I would have never known about it if Keillor hadn’t mentioned it (I’m sure it’s not the museum’s fault, I too have known the joys of working within the constraints of a large municipal website). The model is roughly two and a half feet long, and is almost grotesque in its spindly proportions. Judging by photos accompanying the model, Keillor used a traditional build-up process, rather than the physical-digital hybrid techniques employed in the making of the Dryptosaurus.

Dryptosaurus and Tyrannosaurus both belong to the same group of theropod dinosaurs (tyrannosaurs), but in creating the two models Keillor went in two very different directions when reconstructing their soft tissues. Working with Richard Kissel of the Yale Peabody Museum, Keillor gave Dryptosaurus a patchy coat of shaggy integument, as well as fleshy lips that would easily cover the animal’s teeth if it were to ever close its mouth. However, Carthage College’s Thomas Carr, scientific advisor for Little Clint, requested a scaly hide with a crocodilian tooth-exposing grin.

Little Clint’s toothy grin.

It turns out feathers and lips on large theropods (and tyrannosaurs in particular) are fairly contentious subjects, at least among the sort of people who like to argue about these things on the internet. It is well-established that feathery integument was widespread among theropods, and even certain other dinosaurs. Several members of the tyrannosaur family have been found with fossilized fuzz impressions, including the Dryptosaurus-sized Yutyrannus. This means it’s reasonable to expect that all tyrannosaurs, including Tyrannosaurus rex, were feathered to some degree. However, a recent publication by Phil Bell and colleagues suggests the opposite: an assortment of small skin impressions from Tyrannosaurus and its closest relatives reveal only scaly skin. Meanwhile, ongoing research by Robert Reisz demonstrates that theropods had fleshy lips, but this is contradicted by Carr’s own findings that some tyrannosaurs had armored scales on their maxillary margins.

So which interpretation of tyrannosaur soft tissue is right? For now, there is compelling evidence for both interpretations. Perhaps more fossils or new analytical techniques will eventually steer the consensus in one direction or the other. Or maybe we will never know for sure what the faces of Dryptosaurus and Tyrannosaurus looked like. For now, Keillor’s models make fascinating companion pieces. They are windows into two possible versions of the deep past, reminding us to accept a little ambiguity now and then.

Paleontology Exhibits of California – Part 1

I’ve spent the last week on a whirlwind tour of southern California, visiting natural history museums, zoos, and botanic gardens, as well as seeing a fair assortment of marine mammals. Suffice it to say, my (endlessly patient) travel partner Stephanie and I ended the trip with a bit of sensory overload. I had planned to start off with a brief travelogue post and save more thorough analysis for later, but as usual I’ve gone and written much more than I intended.

La Brea Tar Pits and Page Museum

Howard Ball’s famous mammoth statues in La Brea’s lake pit.

The La Brea Tar Pits (a.k.a. the the tar tar pits) is an iconic fossil locality in downtown Los Angeles. I visited  in my single-digit years, but I remember the site better from documentaries like Denver the Last Dinosaur. The region’s asphalt seeps have been known to local people for thousands of years, and they were first commercially mined in the 1700s, when Rancho La Brea was a Mexican land grant. The animal bones commonly found in the asphalt were seen as a nuisance until 1875, when William Denton of Wellesley College identified a large tooth from Rancho La Brea as belonging to an extinct saber-toothed cat. Several years of largely unrestricted fossil collecting followed, until the Hancock family that had come to own the land gave exclusive collecting rights to the Los Angeles County Museum (now the Natural History Museum of Los Angeles County) in 1913.

Within two years, museum paleontologists had collected about a million bones, mostly from large Pleistocene animals like mammoths, ground sloths, wolves, and saber-toothed cats. This enormous abundance meant that the La Brea fossils were useful not only as research specimens but as trade goods. The LACM amassed much of its present-day fossil collection by trading La Brea fossils to other museums.

The Hancock family donated the 23 acres around the La Brea asphalt seeps to Los Angeles County in 1924. From that point on, the area functioned as a public park, where visitors could learn about ice age California and even watch ongoing excavations. Park facilities and exhibits expanded gradually over the ensuing decades. Sculptures of bears and ground sloths by Herman Beck were added to the grounds in the late 1920s. In 1952, a concrete bunker over one of the excavation sites became the first La Brea museum. The LACM board commissioned the site’s most iconic display – the trio of mammoth statues – in 1965, and sculptor Howard Ball installed them in 1968.

The George C. Page Museum, plus a man who wouldn’t move.

Finally, after years of planning and fundraising, the George C. Page Museum of La Brea Discoveries opened in 1977. The remarkable Brutalist building is adorned by a fiberglass frieze depicting ice age animals in a savanna environment. The aluminum frame holding up the frieze also contains an atrium of tropical plants, which the indoor exhibit halls encircle. Architects Willis Fagan and Frank Thornton designed the museum to fit organically into the established park setting, and to subliminally reflect the fossil excavations it celebrates. The building appears to be erupting from the ground, much like the asphalt and the fossils therein. The entrance is below ground level, so visitors must descend a ramp to meet the fossils at their point of origin.

The giant camel Camelops hesternus (front) with adult and juvenile mastodons (back). Those logs were also hauled out of the asphalt seeps.

Panthera atrox was apparently more like a giant jaguar than a lion. Small-by-comparison Smilodon fatalis in the back.

In many ways, the Page Museum is now a museum of a museum. Most of the interior exhibits, including the fossil mounts designed by Eugene Fisher*, are the same as they were in 1977. Photos show that the exhibit halls, prep labs, and collections areas have changed little in the last 40 years. And that’s okay! The museum building and the outdoor displays around it have been part of the Los Angeles landscape for decades, and cherished by generations of visitors. To the museum’s credit, the 1970s exhibits were well ahead of their time. Windows onto the prep lab and collections would be right at home in modern “inside out” museums, and an oft-repeated message that microfossils (such as insects, birds, rodents, and pollen) are more informative than megafauna fossils vis-à-vis paleoclimate and ancient environments is still very relevant to the field of paleontology today.

That isn’t to say there is nothing new to see. Newer signage around the park grounds does an excellent job re-interpreting older displays, especially those that are now considered inaccurate. For example, Howard Ball’s mammoth statues are probably among the most photographed paleoart installations in the world, but they completely misrepresent the way most of the animals found at La Brea actually died. Ball’s female mammoth is hip-deep in a man-made lake filling in an old asphalt quarry. As the signage (and tireless tour guides) explains, the animals trapped here thousands of years ago actually became stuck in asphalt seeps that were six inches deep or less. Meanwhile, while the classic friezes and murals throughout the Page Museum depict savanna-like landscapes, more recent analysis of microfossils demonstrates that the area was actually a fairly dense woodland.

Turkeys, condors, eagles, and storks are among the more unusual fossil mounts at the Page Museum.

There are two main reasons that the Page Museum is a must-see. First, it provides an in-depth view of a single prehistoric ecosystem. As mentioned, LACM traded La Brea fossils to all sorts of other museums, so chances are you’ve already seen a La Brea Smilodon, Paramylodon, or dire wolf. The Page Museum has these animals, but it also has rarely-seen creatures like ice age turkeys, condors, and coyotes. I counted 25 mounted skeletons in total, to say nothing of the hundreds of smaller specimens. My favorite display was a Smilodon skull growth series, where you can see how the adult saber teeth erupt and push out the baby sabers. In addition, the Page Museum stands right next to the La Brea fossil quarries, past and present. The museum and the park that preceded it were conceived as places where the public could see science in action. Researchers have been uncovering fossils at La Brea for over a hundred years, and visitors have been watching over their shoulders the entire time. That alone makes La Brea a very special place.

*All the La Brea mounts (at the Page Museum or elsewhere) are composites. To my knowledge no articulated remains have ever been recovered from the asphalt seeps. As Stephanie pointed out, the skull of the Equus occidentalis mount actually belonged to a significantly younger animal than the mandible. 

Natural History Museum of Los Angeles County

This Tyrannosaurus growth series is the centerpiece of the LACM Dinosaur Hall.

Our next stop was the Page Museum’s parent institution, the Natural History Museum of Los Angeles County (which I will continue to abbreviate as LACM for consistency). LACM actually features two fossil exhibits: the 2010 Age of Mammals Hall and the 2011 Dinosaur Hall. Both were part of a $135 million project to restore and update much of the LACM building, which first opened in 1913. While the two halls were developed concurrently by different teams, they are architecturally very similar. Parallel mezzanines flank spacious central aisles, which maximizes usable space in the two-story rooms and allows visitors to view most of the mounted skeletons from ground level or from above.

The primary strength of both the Age of Mammals Hall and the Dinosaur Hall is that they look really good. New skylights and newly uncovered bay windows yield plenty of natural light. Primary-colored panels provide interesting backdrops for the specimens, and fossil mounts on the ground and in the air keep visitors looking in all directions. These exhibits were clearly designed to look incredible from the moment you enter the room, and the abundant natural light means they photograph quite well.

Suspended skeletons make use of the vertical space and keep visitors looking all around the exhibit.

Triceratops and Mamenchisaurus at the front end of the Dinosaur Hall.

LACM’s mammal collection has been built up over the last century, while the dinosaur specimens were mostly collected by Luis Chiappe’s Dinosaur Institute in the decade preceding the exhibit’s opening. Nevertheless, both exhibits feature an uncommon diversity of beautifully-prepared fossils. I was particularly taken by the metal fixtures constructed to display incomplete skulls of Augustynolophus and Tyrannosaurus. The mounted skeletons were handled by two different companies: Research Casting International did the mammals and Phil Fraley Productions did the dinosaurs. I actually like the mammal mounts slightly better. There’s a greater range of interesting poses, and they don’t suffer from Fraley’s signature exploding chests.

The Poebrotherium, Hoplophoneus, and Hyracodon mounts are full of life and character.

A metalwork frame artfully shows the missing parts of this Augustynolophus skull.

All that said, there is a surprising divergence in the quality of interpretation between the Age of Mammals Hall and the Dinosaur Hall. On this front, the Age of Mammals Hall is better by far. There is an open floor plan that visitors can circulate freely, but everything comes back to three main ideas posted near the entrance: continents move, climates change, mammals evolve. In no particular order, the exhibit demonstrates how Cenozoic mammals diversified in response to the environmental upheaval around them.

On the ground floor, one tableau shows how dogs, horses, rhinos, and camels evolved to move swiftly across the emergent grasslands of the Miocene. Another area covers how mammals grew larger to adapt to an ice age climate. Overhead, a whale, sea cow, sea lion, and desmostylian illustrate four independent lineages that evolved to make use of marine resources. Exhibits on the mezzanine level focus on how paleontologists learn about prehistoric mammals. One area compares different sorts of teeth and feet. Another explains how pollen assemblages can be used to determine the average temperature and moisture of a particular time and place, while drill cores illustrate how a region’s environment changed over time. Although the exhibit as a whole has no time axis, it does an excellent job conveying how evolution works at an environmental scale.

The addition of dogs, camels, and rhinos makes for an informative twist on the classic horse evolution exhibit.

Struthiomimus is accompanied by a modern ostrich and tundra swan.

By comparison, the Dinosaur Hall doesn’t have any obvious guiding themes. The exhibit is a grab-bag of topics, and to my eyes, specimens and labels appear to be placed wherever they fit. Jurassic Allosaurus and Stegosaurus are surrounded by displays about the end-Cretaceous extinction. Carnotaurus of Cretaceous Argentina is paired with Camptosaurus of Jurassic Colorado. Mamenchisaurus shares a platform with distantly-related Thescelosaurus, which lived 80 million years later on the other side of the world. An explanation of what defines a dinosaur is confusingly juxtaposed with non-dinosaurian marine reptiles. If there’s any logic here, I didn’t see it. This is accentuated by the fact that the label copy is no more specific than a run-of-the-mill dinosaur book for kids. It all feels very generalized and unambitious, especially compared to the Age of Mammals Hall. I would have liked to see more information on what makes these particular specimens special, as well as how they were found, prepared, and interpreted. I suppose it’s up to the visitor whether an exhibit like this can get by on looks alone.

And so concludes day one of our trip. Next time, the Raymond M. Alf Museum and places south!

The Great Mammoth of Lincoln

Lincoln, Nebraska is home to a legendary giant. The University of Nebraska State Museum, known locally as Morrill Hall or Elephant Hall, has the largest mammoth skeleton on display anywhere in the world. “Archie” the columbian mammoth is literally a giant among giants. 14 feet tall and striding on bizarre, stilt-like legs, he towers over the twelve other extinct and extant proboscidians (ten skeletons and two taxidermy mounts) in the museum’s great hall.

Like the Field Museum’s Sue the Tyrannosaurus, Archie is not only a scientific specimen, but something of a mascot. The mammoth is regularly cited as the museum’s star attraction. Its image adorns museum merchandise, and a dancing costumed Archie shows up at local schools and on game days. A bronze sculpture of a fur and flesh Archie created by local artist Fred Hoppe was placed outside the museum’s entrance in 2006, and it is apparently traditional for students to slap its outstretched forefoot for luck. At the center of it all, though, is the real mounted skeleton, which has been on display for 84 years and admired by generations of visitors.

Archie’s skeleton was famously discovered by chickens. In 1921, southwest Nebraska farmer Henry Kariger noticed that his chickens were pecking at some white minerals eroding out of a hillside. Thinking the substance would be a good source of lime for his flock, Kariger started collecting it and adding it to their feed. Eventually the hill eroded further, and Kariger realized he had something more impressive than lime deposits – it was the jaws and teeth of a giant animal.

On November 14, Kariger sent a brief handwritten letter to Erwin Barbour, director of the Nebraska State Museum, describing his find. A geologist and paleontologist, Barbour started his career as O.C. Marsh’s second-in-command at the United States Geological Survey. In 1891, Barbour took the dual posts of Director of the Department of Geology at the University of Nebraska and Nebraska State Geologist. He was appointed Director of the State Museum shortly thereafter, and spent the next fifty years scouring the Nebraskan countryside for fossils to build the museum’s collection. Barbour replied to Kariger two weeks after receiving his letter, informing the farmer that he had found a mammoth, and that he was “entirely sure of this without seeing it.”

Barbour typically received dozens of letters about fossil finds every year, and he gave Kariger the same instructions he gave everyone else: avoid handling the fossils, and absolutely refrain from attempting to extract more bones from the ground. Barbour had seen countless fossils destroyed by overeager members of the public trying to pry them out by hand, or with crowbars. He informed Kariger that the museum would pay for an important find, but only if it was kept intact. Barbour requested that Kariger leave the fossils until the spring, when a museum crew could come out and assess them.

Barbour soon discovered that Kariger had contacted a number of other museums, shopping his find around in an effort to get the best price. In a letter, Kariger informed Barbour that he had been told he had a giant sloth, and that it was exceptionally rare. Barbour held firm, repeating that the find was certainly a mammoth and that he could look at it in the spring. Apparently impatient, Kariger decided to ignore Barbour and got to work excavating the rest of the skeleton, hauling the bones out of the hillside with a team of horses. Miraculously, Kariger did not completely destroy the fossils in the process. With a good portion of a mammoth skeleton in his possession, Kariger brought his find to Lincoln the following summer to display it at the state fair. It was here that Barbour met Kariger – and his mammoth – for the first time. Barbour was suitably impressed, and immediately wrote to Henry Osborn of the American Museum of Natural History, describing the skeleton as complete save for its tusks and the lower portions of its limbs.

According to an account by Walter Linnemeyer (who was about six years old at the time), local authorities discovered that Kariger was selling bootlegged whiskey out of the back of his tent at the state fair, and confiscated both the whiskey and the fossils. Although this makes for an exciting story, Vertebrate Paleontology Collections Manager George Corner confirms that the skeleton “was not confiscated by the Museum or anyone else and then given to the Museum.” In fact, documents in the museum archives confirm that Barbour paid Kariger $250 for the fossils, and that the entirely amicable transfer occurred at the fair in 1922. Since no other documentation about Kariger being involved in illicit sales has surfaced, we must assume that the story is, as Corner puts it, “a product of the times.” Prohibition was the law of the land in 1922, and rumors about sources of illegal liquor must have been common. One might also speculate that anti-government sentiments in rural communities may have played a role in the myth-making.

Another reason to discount the notion that Kariger’s fossils were seized is that he and Barbour maintained a friendly relationship for years afterward. In December 1922, Kariger wrote to Barbour to inform him that he had found one of the missing tusks, but that he had damaged it while removing it from the ground (it didn’t help that his pigs had chewed on it a bit). Barbour once again asked that Kariger leave any further finds buried, reminding him that the museum would pay more for undamaged fossils. Barbour and his student William Hall made the two-day journey to Kariger’s farm the following June. They stayed with the Kariger family for five nights, paying them for room and board, as well as the services of a draft team. Even after resorting to dynamite to blast away the rest of the hill, Barbour went back to Lincoln empty handed. Still, both he and the Karigers enjoyed the experience, and they fondly reminisced about the trip in subsequent letters.

Barbour initially published the Kariger mammoth as a new species, Elephas maibeni, after museum donor Hector Maiben. Osborn’s monograph on proboscidian evolution, posthumously published in 1936, redescribed it as Archidiskodon imperator (hence “Archie”). Archidiskodon has since been folded into Mammuthus columbi, or the columbian mammoth, a species which ranged throughout the western United States and Central America.

When the University of Nebraska State Museum acquired Archie in 1922, space was severely limited. Collections were already stuffed into attics, cellars, and even the steam tunnels between university buildings. Nevertheless, Barbour ensured that at least part of the record-sized mammoth was on display. In 1925, he mounted the forelimbs and part of the torso, forming an archway at the museum’s entrance. A new, larger museum building funded by donor Charles Morrill was completed two years later, and the Kariger mammoth was immediately a candidate for display as a complete mounted skeleton. Barbour sent preparator Henry Reider out that summer to collect isolated mammoth bones that could fill in Archie’s incomplete legs. Soon work on the full mount was underway, with contributions from Reider, Eugene Vanderpool, Frank Bell, and others. The 14-foot tall, 25-foot long mount took years to construct, but was finally completed in the spring of 1933.

Even before Archie was complete, it was clear that the new museum’s central hall would be a showcase for fossil elephants. The lineup of mounted skeletons, which has not changed significantly since the mid-20th century, includes two columbian mammoths, an American mastodon, Stegomastodon, Gomphotherium, Amebelodon, Eubelodon, a pygmy mammoth, and contemporary African and Asian elephants. Elizabeth Dolan provided two parallel background murals which depict elephants around a forested watering hole in an impressionistic style. Today, a contemporary mammoth mural by Mark Marcuson adorns the far wall.

84 years after it was first assembled, the skeleton of Archie the mammoth is a Nebraska icon. Indeed, this mount and the hall it resides in have become a time capsule, a landmark to return to again and again for generations of visitors. Nevertheless, even the most beloved icons are not completely safe. The Nebraska state legislature has repeatedly hit the State Museum with budget cuts, including an astonishing 50% cut in 2003 accompanied by the dismissal of several tenured curators. Thanks to inspired leadership by Director Priscilla Grew, the museum re-earned its accreditation in 2009 and became a Smithsonian Affiliate in 2014. Still, the series of events is a sobering reminder that while museums exist as a public service, they are also dependent on public support. Funding museums must be a top priority if we want legendary displays like Archie to be on exhibit for generations to come.

Many thanks to George Corner for answering my questions about Kariger’s mammoth. Any factual errors are my own.

Looking Back at Fossils: History of Life

The renovated hall 2 upon its initial completion. Photo from Kopper 1982.

It is with some trepidation that I attempt to tell the story of the third incarnation of the National Museum of Natural History’s paleontology exhibits.  For one thing, this was “my” space, insofar that any of us feel ownership over familiar public spaces. I explored these halls regularly as a toddler. I volunteered there as a teenager and interned there after college. More recently, I’ve found myself working among these same displays on a number of occasions as a museum professional*. As such, it is difficult to establish an appropriate amount of cognitive distance, even now that the galleries have been cleared from wall to wall, and new exhibits are being installed in their place.

“Fossils: History of Life” closed for renovation in April 2014. Because this exhibit existed largely unchanged for most of my life, a part of me likes to think of it as something that has always been there. Nevertheless, these displays were designed and built by specific people at a specific point in time. And while the specimens, artwork, and craftsmanship in Fossils: History of Life were nothing short of iconic, the process of putting those pieces together was surprisingly contentious. The creation of this exhibit was beset by internal strife and controversy, as conflicts that had been simmering for decades about the very nature of museums finally came to bear.

The Story So Far

The east wing of the National Museum of Natural History (prior to 1964, the United States National Museum) has been home to fossil displays since the current building opened in 1910. From opening day to 1945, the exhibits were primarily under the stewardship of Curator of Vertebrate Paleontology Charles Gilmore. Intermittently called the “Hall of Extinct Monsters,” this iteration was somewhat haphazard in its layout. Like many early 20th century exhibits, the galleries were filled with a sampling of static objects from the collections, occasionally accompanied by an explanatory painting, map, or model. Gilmore’s version of the east wing remained in place until 1962, when the space was redesigned as part of a Smithsonian-wide modernization project. Between 1953 and 1963, the modernization committee chaired by Frank Taylor oversaw improvements of nearly all of the National Museum’s exhibits. Taylor pushed for exhibits that catered to laypeople, rather than specialists. Paths visitors might travel through the space, common visitor questions, and consistent aesthetics were all considered when overhauling the east wing fossil halls.

As Rader and Cain convincingly argue, the transition from exhibits dominated by cases of specimens with minimal interpretation to story-driven learning experiences began in most American museums at the beginning of the 20th century. However, this was not the case at the Smithsonian. By the 1950s, the National Museum had developed a reputation as an old-fashioned place. Its neo-classical exhibition halls mostly contained rows of cases jam-packed with specimens, and that was the way the curatorial staff liked it. Entomologist Waldo Schmitt summed up the prevailing institutional attitude when he said that exhibits should be nothing more than “show windows for displaying our wares and accomplishments.” Curators like Schmitt worried that shoehorning objects into generalized narratives about nature and anthropology would distort or occlude their meaning and provenance. NMNH Director Remington Kellogg agreed, and Taylor’s modernization committee faced an uphill battle with every exhibit they sought to make more broadly accessible.

It was a stalemate between two competing visions for what a museum should be. The 1962 fossil hall renovation at NMNH experimented with dioramas, color-coded signage, and text divided into area titles, headings, and subheadings, but compared to peer institutions it was hardly revolutionary. This could be partially attributed to the design process, in which the development of each of the four east wing galleries (halls 2, 3, 4, and 5) was led by a different curator. As a result, the galleries landed in different places on the spectrum between traditionally-arranged specimens and cohesive narratives.

The 1974 Ice Age Hall was a turning point for NMNH exhibits. Photo by the author.

Nevertheless, a turning point was on the horizon. The east wing modernization plan also called for the annexing of hall 6 (formerly the home of geology exhibits) as a dedicated Hall of Quaternary Vertebrates. In part due to the larger number of new specimens being prepared for display, this Quaternary Hall was repeatedly delayed. By the time hall 6 was ready to reopen in 1970, its old-fashioned organization was no longer what administrators wanted. In 1973, Director Porter Kier decided to shut down the nascent Quaternary Hall and assemble a new team to redesign it. A group of geologists, anthropologists, paleontologists, and education specialists reworked the exhibit into an interdisciplinary exploration of the ice ages. Continental glaciation, the evolution and extinction of large mammals, and the rise of humans were all presented as a single, holistic story. For NMNH staff, it was clear that the 1974 Hall of Ice Age Mammals and the Rise of Man represented the future of exhibition at the museum. From that point onward, exhibit design would be a collaborative process between curators, educators, and exhibit specialists. Moreover, the galleries themselves would be seen more like fully-formed architectural spaces, rather than modular associations of artifacts. Above all, the primary purpose of exhibits would be the education and engagement of visitors.

Planning “History of Life”

After the positive reception of the Ice Age Hall, Kier were eager to retool the rest of the ever-popular paleontology galleries in the same manner. In early 1977, he appointed fossil cnidarian specialist Ian Macintyre to chair a committee of curators tasked with devising an overarching plan for the exhibit renovation. Joining Macintyre was Daniel Appelman (geology), Robery Emry (fossil mammals), Leo Hickey (fossil plants), Nicholas Hotton (fossil reptiles), Kenneth Towe (early atmosphere), and Thomas Waller (fossil mollusks). In June, the group submitted their theme statement:

The fundamental theme which has been developed in the context of a single all-encompassing hall is the history of the progress of life as revealed by the geological record in terms of:

  1. The great periods of time involved in the evolution of life forms preserved
  2. The changing environmental conditions associated with the evolutionary process
  3. The increase in diversity and complexity of life forms

The phrase “all-encompassing hall” is key. The curators agreed that, unlike the 1962 iteration, the new exhibit should have a single voice and follow a single narrative. This decision was influenced not only by changing expectations for exhibits, but also by recent developments in their own department. The NMNH Division of Paleontology had been disbanded in 1963, and paleontologists were reorganized into the Department of Paleobiology. The new title represented a push among research staff to focus less on descriptive systematics and more on how the fossil record can inform our understanding of evolution and ecology. Macintyre’s team wanted to bring the same change of focus to the new exhibit.

The curators spent the next year hashing out the hall in further detail. Early on, the group agreed that an illustrated column of geologic time should be the exhibit’s centerpiece. This would eventually manifest as the “Tower of Time,” with key artwork provided by John Gurche. The group also decided to break the main “progress of life” concept into several smaller storylines, which they counterintuitively called “highlights.” The highlights would include “The Earliest Traces of Life,” “Conquest of the Land,” “Reptiles: Masters of the Land,” “Living Fossils,” “Fossils and Industry,” and “Mammals in the Limelight,” among others.

Each highlight would correspond to a part of the east wing exhibit space. The central, high-ceilinged hall 2 would be occupied by Reptiles: Masters of the Land, which included the dinosaurs, as well as a substantial display of of Paleozoic marine invertebrates at the rotunda-side entrance. A new mezzanine and ramp over hall 2 would include Living Fossils, Fossils and Industry, the evolution of flight, and fossil fishes. Hall 4 would feature Earliest Traces of Life and Conquest of the Land. Mammals in the Limelight would occupy hall 3, and hall 5 would remain empty for the time being. For practical reasons, the highlights would each be overseen by a different subcommittee of specialists, and they would be built and unveiled on a staggered schedule. Still, the main committee would oversee the entire process and make sure the writing and visual design of each section came across as parts of a cohesive whole.

Between the lines, the need to include dinosaurs was apparently seen as a nuisance by at least some of the curators. There were no dinosaur specialists on the exhibit team, and indeed, NMNH had not employed one since Gilmore retired in 1945. Although the dinosaur renaissance was picking up speed by the late 70s, for NMNH paleontologists dinosaurs were overexposed and less interesting than their own research subjects. The museum’s eleven dinosaur mounts were decades-old relics, but their popularity among visitors obligated the curators to include them. Disarticulating and remounting the skeletons was not in the budget, and many of the dinosaurs were too big to cart out of the hall in one piece. That left the exhibit team with the unenviable task of finding places for the existing mounts in addition to all the new specimens and models they wanted to add, while still leaving enough room for visitors to get around. As internal legend has it, the giant slab of Climactichnites tracks was placed at the front of hall 2 specifically to block the view of the dinosaurs from the rotunda.

Although Macintyre and his curator colleagues were the only formal members of the exhibit committee, the Department of Exhibits was also involved from the start. Exhibits staff at NMNH had increased from six people in the 1960s to over 30 by 1985. This expanded force included all manner of artists, architects, industrial designers, and communications specialists, and they had an impressive on-site workshop to make use of their talents. In the 1980s, everything from silk-screened signage to cabinetry to dioramas could be created in-house. However, the increased professionalization of exhibits specialists required curators to relinquish some of the control they historically had over displays.

This, unfortunately, led to the two departments regularly butting heads. Curators complained that exhibits staff did not know enough of the science, and that the ideas they were generating simplified content to the point of being inaccurate. Meanwhile, exhibits staff had to deal with the fact that the curators had final approval authority over all content, but typically saw the exhibit work as secondary to their research obligations. Deadlines were routinely missed, leading to frenzied, last-minute crunch periods. The result was signage with avoidable errors making it the exhibit floor, and a culture of finger pointing in all directions.

Two postdoctoral research associates – Jessica Harrison and George Stanley – were brought on board to help with the exhibit design and construction. Harrison and Stanley had offices in both the Exhibits and Paleobiology departments, and were well-liked by both groups of staff. The most difficult part of their job was drafting label copy. Text had to be rewritten again and again to please educators who found it too technical and content specialists who demanded more precision and detail. Harrison in particular was widely praised for effectively explaining scientific concepts to the exhibits staff and for guiding the key themes of the exhibit from concept to completion.

Specimens and Artwork

The east wing exhibits formally closed for renovation on May 29, 1979. In spite of the administrative-level disagreements, the museum’s technical staff was producing great creative work in short order. The recent expansion of the Department of Exhibits meant that nearly everything that went into the exhibit was created in-house (today, large exhibits are created largely in collaboration with contractors). Only the biggest construction projects, such as the addition of a mezzanine over hall 2, had to be contracted out.

Scores of never-before-exhibited specimens were prepared for Fossils: History of Life. Examples include a 4.6 billion-year-old meteorite from Australia, the reconstructed jaws of Carcharocles megalodon, and curator Nicholas Hotton’s beloved Thrinaxodon fossil, which he called “baby doll.” Preparator Arnold Lewis led the creation of the new mounted skeletons, which included Eryops and Strobodon. Some existing mounts were updated, including Dimetrodon, which was given a longer tail. The most ambitious new mount was Allosaurus, or as Hotton insisted on calling it, “Antrodemus.” The Allosaurus (USNM 4734) came to NMNH in the 1890s with the rest of the Marsh collection, but only the skull and a few other pieces had ever been displayed. Lewis spent two years creating the mount. He started by preparing the bones that had never been completely freed from the matrix they were found in. After laying the skeleton out in a giant sandbox, Lewis secured the bones one at a time to a custom steel armature. This form-fitting structure proved to be almost invisible against the dark grey bones. Unlike most theropod mounts of the time, Lewis’s Allosaurus included belly ribs, modeled in rubber after those of a crocodile.

Fossils: History of Life also called for a number of new paintings and dioramas. Peter Sawyer painted a cyclorama of a primordial Archean landscape for the Earliest Traces of Life section. Robert Hynes contributed several murals, as well, including a beach scene and a Cooksonia marsh for Conquest of the Land. In addition to the key art on the Tower of Time, John Gurche provided illustrations for the horse evolution cul-de-sac and the backdrop for a new lungfish diorama. Jay Matternes’ Cenozoic murals were carried over from the old exhibit.

George Merchand’s marine dioramas and Norman Deaton’s dinosaur dioramas were reused, while the NMNH exhibits shop produced several brand new displays. In addition to the aforementioned lungfish scene, these included a recreation of the Burgess Shale environment and a group of eurypterids patrolling the Silurian shallows. There was also a walk-through diorama of a Cretaceous Maryland forest, featuring reconstructions of some of the earliest flowering plants.

The Smithsonian’s central exhibit shop handled the most challenging projects. Their biggest contribution was the life-sized Quetzalcoatlus model. The artists started with a clay miniature, then moved on to a 1/6th scale fiberglass model. With final approval from Nicholas Hotton and Jessica Harrison, the team moved on to the 40-foot final version. The wings were constructed like those of airplanes, with a hollow steel rod supporting wood and aluminum trusses. The wing membranes were plastic, and translucent in the right light. The head and legs were sculpted in clay then cast in plastic, and the body was covered in deer fur. Exhibits Central also built a set of cycads to accompany the historic Stegosaurus model. Several of these were real conifers, freeze dried and covered in glycerin.

Finally, Fossils: History of Life included some of NMNH’s first forays into video displays. The “Enter Life” film explored possible scenarios for biogenesis. An animated film starring “Frank Anchorfish” and “Arthur Pod” (voiced by DC-area newscasters) was a whimsical take on the challenges of moving from the aquatic to the terrestrial realm. A popular, albeit short lived, part of the exhibit was “A Star is Hatched,” which featured clips from Hollywood dinosaur movies accompanied by discussion of dinosaurs’ pop culture significance.

Legacy

On April 17, 1980, Hall 4 – with exhibits covering the origins of life, the transition to life on land, and Paleozoic and Mesozoic plants – was the first part of the east wing to reopen. The dinosaur-filled hall 2 followed on December 4, 1981. These initial phases of Fossils: History of Life were generally well-received by the public, although some media critics scoffed at the silly puns and cultural references in the label copy (“A duckbill in every pot,” “the better to eat you with, my dear,” and so forth). Robert Emry took over for Ian Macinyre as lead curator for the final phase of development and construction. After a few delays, Mammals in the Limelight in hall 3 was ready for visitors on May 30, 1985.

Behind the scenes, the occasionally tense working relationships and difficulty meeting deadlines contributed to major changes to how exhibits are put together at NMNH. When Richard Fiske took over as Director in 1983, he promoted Beth Miles, Sheila Mutchler, and Sue Voss from the Department of Exhibits to formal members of the paleontology exhibit team. A dedicated project manager position was added, and formal guidelines were prepared for exhibit-related duties. A key part of this formalized exhibit protocol was explicit acknowledgement that exhibits (not research and collections) are the public face of the museum and therefore the primary impetus for public support. Maintaining that support meant creating visitor-focused exhibits that are as relatable, educational, and entertaining as possible. This effectively killed the old idea of exhibits as mere showrooms for collections. Research and collections staff were no less important to the identity and purpose of the museum, but as far as exhibits were concerned their content knowledge would have to go hand in hand with other kinds of expertise. Exhibits and education specialists took leadership roles on future exhibit projects, a system which remains in place to this day.

Fossils: History of Life saw many changes over its 33 year life span. A Star is Hatched was one of the first displays to go. While popular among visitors, scientific staff hated the film because it trivialized exhibit content and featured long-outdated images of dinosaurs (interacting with modern humans, no less). The theater built for A Star is Hatched was eventually demolished and replaced with a windowed fossil prep lab, which became one of the most popular parts of the exhibit complex. An enclosure housing a live caiman in the Living Fossils area of the mezzanine only lasted as long as the animal. When the caiman died, the exhibit was boarded up and never replaced. Later, the Flowering Plant Revolution area – including the walk-through diorama – was dismantled to make way for a concessions stand. The largest addition to the east wing was Life in the Ancient Seas, an exhibit of marine fossils that filled the unused portion of hall 5. Completed in 1990, Life in the Ancient Seas nearly doubled the number of specimens in the fossil halls and added a splash of color with Ely Kish’s 150-foot mural of extinct marine life.

More recently, three of the historic dinosaur mounts were taken off exhibit and replaced with updated casts. Triceratops, Camptosaurus, and Stegosaurus had been on display since 1905, 1912, and 1913, respectively, and a century of vibration from passing crowds and fluctuating temperature and humidity had taken their toll on the fragile fossils. Ralph Chapman took the opportunity to turn the Triceratops into the world’s first digitized dinosaur, pioneering a process that is standard practice today. The Triceratops that returned to the hall in 1999 was made from foam and plastic molded directly from digital scans of the original fossils. It was accompanied by a mini-exhibit that explained how the new mount was made, and featured artwork by Bob Walters in addition to several new original and cast skulls. Shortly thereafter, NMNH acquired a cast of Stan the Tyrannosaurus as a conciliation prize for missing out on SueCamptosaurus and Stegosaurus were removed and replaced more quietly, but these mounts are of note because much of the casting and restoration work was done by a crew of veteran volunteers.

The mezzanine over hall 2 was closed for safety reasons after a 2011 earthquake. These exhibits never reopened, which meant that visitors could no longer see the pterosaurs, phytosaurs, and Xiphactinus. In the exhibit’s final years, an assortment of new signs were added, including updates to geologic time scale and an explanation of the dinosaur-bird connection. Unfortunately, these updates amounted to little more than bandaids for an increasingly tired exhibit.

In retrospect, Fossils: History of Life was conceived at an inopportune time. Some aspects, like the focus on biology and evolution rather than classical systematics, were cutting-edge. However, much of the exhibit content was quickly outmoded by sweeping changes to the field of paleontology that occurred during the 80s and 90s. Conservative ideas about dinosaur endothermy and bird evolution were obsolete within a decade, as was much of the pre-cladistics taxonomy and the central theme of evolution as progress. The exhibit team could not have known how different our understanding of paleontology would be just a few years after the renovated halls debuted.

Moreover, the fact that Fossils: History of Life was built over the skeleton of the 1963 renovation (which was, in turn, built on top of the original east wing exhibits) proved to be a significant handicap. Since the space was never completely gutted, the designers had to work around existing specimens and structures, such as the 80-foot Diplodocus and the three separate doorways off of the rotunda. As a result, creating a logical path for visitors to follow through the halls proved impossible. Updates and additions to the exhibit only exacerbated the issue. As it stood in its final years, there was no way to view Fossils: History of Life in historical order without repeatedly doubling back. Bottlenecks that impeded traffic flow were also a problem, especially during mid-afternoon rush hour at the T. rex.

Despite these issues, Fossils: History of Life was seen – and loved – by tens of millions of visitors during its 34 years on display. After many false starts, in 2012 NMNH was finally able to secure the funding needed to overhaul the east wing properly. For the first time, the five galleries are getting a top-to-bottom revamp: every specimen has been removed and every corner of the exhibit has been redesigned, word by word and inch by inch. The bad news was that this process would take five years. Word about the lengthy closing resulted in minor outrage, particularly from parents of young children. After four decades of designing, building, maintaining, and updating the hall, Museum staff understood completely. As Director Kirk Johnson told the Washington Post, “it’s an iconic, favorite space. People have made lots of memories here.”

Painting the Ancient Seas

During a 1958 benchmarking trip to a number of North American natural history museums, Smithsonian exhibits specialist Ann Karras wrote to Assistant Secretary Remington Kellogg about the state of artwork in paleontology displays. She noted with some frustration that since the paleontological community’s early 20th century love affair with Charles Knight, very little had been accomplished in this field. Everywhere she went, Karras saw reproductions of the same decades-old Knight paintings, supplemented by only the most tentative attempts at original artwork. As Karras postulated, “reverence for [Knight’s] work on the part of paleontologists may have thwarted any ambitions in that area of illustration for some years.” The sole outlier was the Peabody Museum of Natural History, home of the 1947 Age of Reptiles mural by Rudolph Zallinger. Impressed by the scale and quality of this 110-foot fresco, Karras suggested that the Smithsonian  invest in a similarly monumental piece of up-to-date paleoart at some point in the future.

Karras’s wish was finally realized in 1990, with the debut of Eleanor Kish’s epic Life in the Ancient Seas mural in the exhibit of the same name. Sixteen feet high and 130 feet long (with a sixteen by twenty foot supplement on the opposite wall), this mural is even larger than Zallinger’s better-known magnum opus. It also covers more of Earth’s history, spanning 541 years of deep time across the entire Phanerozoic Eon. But while The Age of Reptiles charts the progression of life on land, Life in the Ancient Seas follows the denizens of the undersea realm. From the explosion of invertebrate diversity in the Cambrian to the proliferation of aquatic mammals in the recent past, the mural demonstrates that the history of life is most thoroughly documented by marine fossils.

The idea to include a mural in the Life in the Ancient Seas exhibit came relatively late. There was no mention of the artwork in the 1987 briefing document for potential donors, and as late as June of that year curator Nicholas Hotton was writing in hopeful terms about the inclusion of a full-color illustration of Dolichorhynchops. Eventually, however, the exhibit team got the go-ahead to start looking for an artist. Content Specialist Linda Deck started by assembling a list of three dozen prominent paleoartists. She sent each of them a letter of invitation, describing the project and emphasizing the immense scale of the desired product. Half of the artists responded with resumes and portfolio samples, and from these the exhibit team narrowed the field to six candidates*.

The short-list candidates were then given a $1000 stipend to paint a small sample piece. Each artist was provided with the scenario (a group of ammonites releasing a cloud of ink upon being attacked by a mosasaur), an assortment of fossil reference photos, and encouragement to get in touch with NMNH curators as needed. Of the five artists who completed this challenge, the exhibit team agreed unanimously that Kish’s work was the best fit for the project. Not only did she demonstrate the ability to accurately render the animals with anatomical precision, her bold color palate would work well as the backdrop for the entire exhibit.

Eleanor (or Ely) Kish was born in 1924 to a family of artists. Growing up in New Jersey, she became a naturalized Canadian citizen in 1972. While Kish was a professional artist for most of her adult life, her career in paleontological illustration kicked off in the 1970s, at Ottawa’s Canadian Museum of Nature. It was there that she worked with paleontologist Dale Russell on some of the earliest Renaissance-era dinosaur reconstructions (an assortment of paintings from Russel’s An Odessey of Time: The Dinosaurs of North America can be seen here). Tales of dinosaur art from this era often focus on Gregory Paul, John Sibbick, and their imitators, but Kish’s work was similarly prominent in books and magazines of the day.

Kish’s art is instantly recognizable for its portrayal of active, highly expressive dinosaurs in breathtakingly realized landscapes. The worlds she created – particularly the skies – have an almost poetic beauty, while the plants and animals that inhabit them drip with dew and pulsate with life. Kish’s work is often overlooked today because her dinosaurs are shrink-wrapped in the extreme, sometimes appearing emaciated or even ghoulish. The skeletal look is very much out of vogue (modern paleontologists prefer their dinosaurs appropriately bulked out with muscle, fat, and feathers), but as Christian Kammerer pointed out on twitter, it’s important to consider Kish’s art in context. Her carefully-researched work was a powerful counterpoint to the rotund, shapeless dinosaurs that had dominated paleoart in preceding decades, and a critical step on the road to the reconstructions we know today.

Once she received her work visa in May 1988, Kish moved to the Washington, DC area to begin Life in the Ancient Seas. She began by constructing small models of the most prominent animals that would appear in the mural. Working primarily with Sculptey, she built the animals’ skeletons first, using fossil photos as reference. Once these were approved, Kish sculpted the animals’ musculature and outer surfaces. She then used her models to paint a 16-foot small scale (1.5 inch to 1 foot) pencil sketch of the mural. This enabled her to work out the poses and behaviors of the animals, as well as the overall composition of the artwork. The next step was to produce the “color comprehensive”: a miniature painting with all the detail of the final piece. Since it would be impossible to photograph the entire mural within the narrow confines of Hall 5, this is the version that was reproduced for books, magazines, and postcards.

After fourteen months of preliminary work, Kish applied the first brushstrokes to the wall in the Spring of 1989. The museum’s graphics shop had prepared the surface well in advance, laying overlapping sheets of canvas onto drywall and carefully buffing out wrinkles and tears. Kish painted 130 feet of ocean backdrop for the main mural first, which took nearly two months. Next, Kish completed the smaller Cretaceous mural on the south side of the gallery, then moved on to the daunting task of filling in the large mural. She populated the scene chronologically, starting with the Paleozoic on the far left and moving forward through time. The exhibits department coordinated closely with Kish, so that the rest of the exhibit could be installed in her wake as each section of the mural was finished. The project took a total of two years to complete.

Life in the Ancient Seas is an absolute masterpiece. Within the exhibit, this meticulously crafted image defines the space’s layout and color palate. It visually separates concepts and themes, and even directs visitor traffic with it’s strong leftward momentum. But Life in the Ancient Seas is the rare piece that was designed for a particular space, yet still holds up as a beautiful work of art on its own terms. The three biggest animals – Dunkleosteus, Tylosaurus, and Basilosaurus – anchor the action and provide a focal point for the viewer. From there, dynamic schools of fish draw the eye back and forth across the canvas. The longer one looks at this vibrant and colorful seascape, the more details emerge.

Of course, the primary function of the mural is to bring the static fossils on display to life, and Kish does not disappoint. The canvas is filled with hundreds of animals in perpetual motion. Streams of bubbles erupting from the creatures’ mouths imbue them with breath and energy. Although plenty of animals are being eaten, Life in the Ancient Seas is not a savage struggle of life and death. In one area, an inquisitive shark gets a face full of ink from a cephalopod that has no time for its antics. In another, a school of fish is sent careening in different directions by the powerfully swishing tail of the Tylosaurus. Instead of focusing on the macabre, Kish brilliantly incorporates whimsical humor into her work without plunging into the realm of cartoonishness. It is a feat that other paleoartists might do well to emulate. Meanwhile, Kish cleverly grounds some of the stranger extinct animals by juxtaposing them with their more familiar brethren. For example, the association of Basilosaurus, which resembles a fanciful sea dragon, with comparably mundane dugongs and dolphins makes this serpentine ancestral whale seem more plausible.

Life in the Ancient Seas was the largest project Kish ever took on. As she stated in multiple interviews, the Smithsonian commission made her career. The money she earned allowed her to buy a rural home in Ontario and convert it into a studio, which allowed her to produce more work more quickly. “I always wanted a studio,” she told the Ottawa Star,  “but I never had the money. The Smithsonian gave me that chunk of cash.”

Ely Kish passed away on October 12, 2014 at the age of 90. Those who knew her are quick to mention her kindness and generosity, particularly toward young artists. Past colleagues also fondly recall her impressive bouts of swearing, which would occasionally punctuate her normally soft-spoken demeanor. For the rest of us, we have Kish’s amazing artwork to remember her by. Kish created worlds we could otherwise never see, and she did it on a breathtaking scale. Although hers was a visual medium, she made the past into something we could feel and even experience. She and her talents will be missed.

History of the Field Museum Fossil Halls – Part 2

Start with History of the Field Museum Fossil Halls – Part 1.

Where we left off, the fossil exhibits in Halls 37 and 38 at the Field Museum of Natural History had gone for decades without more than piecemeal improvements. In the meantime, the field of paleontology – and our understanding of dinosaurs in particular – had progressed by leaps and bounds. What’s more, standards for natural history exhibits had changed. Cases of specimens with esoteric labels written by curators past were no longer enough. Visitors expected exhibits that were relatable and accessible for children as well as interested adults, and multimedia and interactive elements had become standard. This combined with ever-growing public interest in all things prehistoric gave Field Museum staff serious incentive to start with a clean slate.

Phase III: Life Over Time

The end of the old fossil halls came not with a bang but with a whimper. In 1990, specimens started disappearing and areas were roped off without warning. Hundreds of specimens were relocated to Halls 25, 26, and 29 on the other side of the second floor, where they would be part of the exhaustive new exhibit “Life Over Time.” Meanwhile, Halls 37 and 38 became the home of the pacific islands exhibit and Ruatepupuke II, the Maori Meeting House.

As the name suggests, Life Over Time was a chronological journey through the history of life, from its origins around four billion years ago up to the last ice ages. Paleobotanist Peter Crane chaired the Geology Department during the development period, and geologist and children’s education specialist Eric Gyllenhaall oversaw the contractors and in-house staff that created the the exhibit itself. In total, the project took five years and cost $7 million.

Gyllenhaal and the rest of the team conceived of Life Over Time as a directed experience. The space was shaped like a U, with switch-backing corridors flanking a more open dinosaur section in the middle. With the exception of a shortcut between the Carboniferous and the Mesozoic, visitors had no choice but to walk through the exhibit chronologically, viewing the displays in the order the designers mandated. Since visitors tend to be more focused and more likely to read signs early in the exhibit, the designers deliberately used the introductory rooms to cover the most unfamiliar concepts. Displays on the origins of life and the evolution of aerobic respiration made up the “homework” part of the exhibit. After that, visitors were set free in the Mesozoic section, where open sight lines allowed people to choose what they wished to view, and in what order. This served as a reward for putting up with the more challenging material early on. Ultimately, what set Life Over Time apart from its predecessors was the focus on ideas rather than specimens. The fossils were meant to illustrate broader concepts like adaptation, extinction, and biogeography, and were in some ways subordinate to the hands-on activities and multimedia displays.

The process of developing Life Over Time was an occasionally tense give-and-take between the research staff (who traditionally had the last word on exhibit content) and the administrators, exhibit specialists, and educators (who had greater influence this time around). Looking back, it would seem that the curators lost more of these fights than they won. Life Over Time ended up with a decidedly kitschy tone, and was full of overtly silly elements. The exhibit entrance featured carnival-style banners advertising “Primordial Ooze” and “Dunkleosteus: Jaws of Death.” Further on, a mannequin dressed as a game show host invited visitors to spin the “Wheel of Adaptation.” There were Dial-A-Dinosaur phones, which visitors could pick up and listen to first-person accounts of life as a dinosaur. An animatronic puppet show explained the switch from aerobic to anaerobic life. Video “weather reports” with CBS anchor Bill Kurtis updated visitors on climate change over time. There was even a ridable trilobite on a spring.

This carnival-like atmosphere is particularly distinctive when compared to the present fossil halls at the American Museum of Natural History, which were developed at the same time. AMNH project director Lowell Dingus rejected contemporary trends in exhibit design, which, in his view, were pitched to “the lowest common denominator of visitor intellect.” Wishing to challenge audiences to think about fossils the way scientists do, Dingus created a phylogeny-based exhibit that emphasized empiricism and rigorous anatomical analysis over idle speculation. While it was certainly not devoid of informative content, Life Over Time was designed for a much younger audience, with particular attention paid to the under-five set. This marked contrast between the New York and Chicago exhibits speaks volumes about the differing influence of the scientific staff at the two museums, as well as the institutions’ overall priorities at the time.

Happily, the Field Museum didn’t opt to replace its authentic mounted fossil skeletons with the roaring robots that were in vogue at the time. The classic fossil mounts were restored and rebuilt by Prehistoric Animal Structures, Inc., a Canadian company headed by Gilles Danis. A biologist by training and a veteran of the Royal Tyrell Museum, Danis led the process of disassembling, cleaning, and remaking the most significant mounts. The ApatosaurusDaspletosaurus, and Megathierum were all given more accurate and active poses: the Daspletosaurus now crouched over its Lambeosaurus prey with its tail held aloft, while the giant sloth stretched to its full height against a replica tree. Although it was completely rebuilt, the Apatosaurus retained its dragging tail in the new exhibit – an unusual choice for a 1990s reconstruction.

In addition to the classic mounts, Life Over Time featured a partial Parasaurolophus and a new cast of the AMNH Triceratops. The most substantial addition was a complete Brachiosaurus reconstruction. This 40 foot tall mount combined casts taken from the material Elmer Riggs collected at the turn of the century with sculpted elements prepared by Stephen Godfry.  Far too large for the second floor exhibit halls, the Brachiosaurus earned a place of honor in the central Stanley Field Hall. In order to comply with the fire code while allowing visitors to walk under the towering sauropod,  the torso was extended by adding two extra dorsal vertebrae (for a total of twelve). In an amusing twist, newer research shows that this vertebrae count – and the mount’s stretch limo proportions – is probably correct.

Life Over Time opened to the public in June 1994 (the Brachiosaurus had been on display for a year prior). Nevertheless, it was the shortest-lived iteration of the Field Museum’s fossil displays, closing down after only ten years. Why didn’t it last? For one thing, the numerous interactive elements suffered more wear and tear than expected, and they broke frequently. Meanwhile, in-house evaluations showed that the exhibit’s intended messages were not coming across to most visitors. For example, Asma recalls a child frantically spinning the Wheel of Adaptation with all his might, completely oblivious to the information the display was meant to convey. Unfortunately, an interactive exhibit is not necessarily an educational one, and it can be very difficult to create a learning experience that accomplishes both goals.

Phase IV: Evolving Planet

There was one more reason the Field Museum needed to revisit its fossil displays: the sudden acquisition of Sue the Tyrannosaurus in 1997. The story of the four-way legal battle that preceded this has been told often (although not always fairly), so suffice it to say that few came out of that fight unscathed. The Field Museum entered the picture when landowner Maurice Williams, to whom the courts had awarded ownership of Sue, announced that the fossils would be placed on the auction block. Paleontologists initially worried that the priceless specimen would disappear into the hands of a wealthy collector, or end up in a crass display at a Las Vegas casino. Those fears were put to rest when the Field Museum won Sue with financial backing from McDonald’s and Disney. Including the auctioneer’s commission, the price was an astounding $8.36 million.

The Field Museum committed to a summer 2000 unveiling of Sue’s mounted skeleton. However, most of the bones was still buried in rock and plaster. The fossils had to be prepared and stabilized before they could be studied, and they had to be studied before they could be mounted. Most of this work was done on-site, in view of the public. The armature itself was created by Phil Fraley Productions, the same exhibit company that rebuilt the AMNH Tyrannosaurus. Field Museum administrators decided that Sue would replace the Brachiosaurus in the Stanley Field Hall, even though the sauropod had only been on display for seven years. According to Exhibit Project Manager Janet Hong, Sue was such a monumental exhibit that it really deserved pride of place. Meanwhile, the Brachiosaurus was relocated to O’Hare International Airport, while a weather-proof duplicate was placed outside the museum.

Sue was revealed to the public on May 17, 2000 with the literal raising of a curtain. A week-long series of celebrations and press junkets introduced Sue to Chicago, and it has been one of the city’s biggest attractions every since. All the publicity paid off, at least in the short term: Field Museum attendance soared that year from 1.6 million to 2.4 million. 16 years later, Sue’s new identity as a Chicago landmark seems to have all but eclipsed the legal dispute that was its original source of fame. Hong likens Sue to Chicago’s David, and even former Field Museum President John McCarter feels that he underestimated what a force Sue would be for the city.

The acquisition of Sue created a strong public association between the Field Museum and dinosaur research. This was ironic, because while the museum had hosted a talented array of paleontologists over the years, it had never employed a dinosaur specialist. Even Elmer Riggs, who collected the museum’s iconic sauropods at the turn of the century, was more interested in mammal evolution. In 2001, the Field Museum began a concerted effort to expand its vertebrate paleontology program, and make a name for itself as a hub for dinosaur science. Among the new hires were fossil preparator Akiko Shinya and paleontologist Peter Makovicky, who immediately began organizing expeditions to grow the museum’s collection.

The new emphasis on paleontology research brought greater expectations for the Field Museum’s interpretive efforts, and Life Over Time wasn’t doing the job. The initial plan was to merely refresh the decade-old exhibits, but ambitions grew and the renovation snowballed into something much more substantial. Project Manager Todd Tubutis and Content Specialist Richard Kissel spent five years overseeing the development of Life Over Time’s replacement, eventually titled “Evolving Planet.”

While the new exhibit uses the same space and directed, U-shaped layout as its predecessor, the end result is virtually unrecognizable. The hokey parts of Life Over Time are gone, replaced by all-new signs, labels, and interactives. New specimens include original Parasaurolophus, Rapetosaurus, and Arctodus mounts, plus casts of Stegosaurus and Deinonychus, all prepared by Research Casting International. An entire room is dedicated to fossils from Utah’s Green River Formation, acquired on a recent Field Museum collecting expedition. Phlesh Bubble Studios provided a panoramic CGI reconstruction of the Burgess Shale Fauna, while Karen Carr produced 150 original paintings to supplement the classic Charles Knight murals. These, in turn, were restored by Parma Conservation and are contextualized as the historic masterpieces they are. Nevertheless, Evolving Planet has a few holdovers from Life Over Time. The existing dinosaur mounts were not moved or changed, and major set pieces like the walk-through Carboniferous swamp diorama remain in place.

The interpretation in Evolving Planet arose from three main objectives. First, the exhibit needed to highlight the Field Museum’s own collections and the work of its in-house research staff. Second, it had to contextualize Sue and the environment they lived in. Finally, it had to effectively explain the process of evolution, and the evidence for it. Life Over Time had faltered here, and with the influence of the anti-science lobby increasing, it was crucial to get it right. Tubutis and Kissel accomplished this in part by facilitating closer collaboration between the exhibit designers and research staff. Evolving Planet weaves the evidence for evolution into all aspects of the displays. The first thing visitors see is the thesis of the exhibit – “everything that has ever lived is connected through and is the result of evolution” – printed on an otherwise blank wall. Moving forward, visitors learn how evolution via natural selection works, and how we know. Along the way, common misconceptions, such as the idea that lineages improve over time, or that evolution is “just a theory”, are proactively addressed and corrected.

The visual design of Evolving Planet deserves particular mention. The new exhibit subtly but effectively uses repeating iconography to guide visitors through the story being told. Every geological period is associated with a specific color scheme and soundscape, making visitors’ progression from one stage to another obvious and distinct. “Timeline Moments” at the beginning of each section update visitors on their progress, and ensure that they expect to see something new and different up ahead. Special symbols remind visitors of recurring themes, such as mass extinctions (or even the repeated evolution of saber-teeth). Lastly, variations in font and text size are cleverly employed to call attention to key words and phrases.

Evolving Planet opened on March 10, 2006. A decade later, this award-winning exhibition remains a favorite with scientists and educators alike. As Cleveland Museum of Natural History Educator Ashley Hall explains:

Evolving Planet is my all-time favorite museum exhibit. It is not only rich with some of the world’s best known fossil specimens, but provides label copy for visitors of all learning levels. You can visit multiple times and still learn something new. Museums provide visitors with unique settings for learning, and it is a museum’s job not to short-change, dumb down, or simplify information. Evolving Planet hits the nail on the head.

From its clear-as-day thesis to its poignant finish (a counter showing the number of species going extinct daily), Evolving Planet is ambitious but uncommonly relatable. It places familiar dinosaurs and mammoths in a broader evolutionary context, introducing visitors to the true breadth of deep time. And yet, the exhibit is also remarkable for its restraint. It doesn’t overwhelm casual visitors with specimens and facts, but instead sticks to a handful of broadly-applicable themes.

The Field Museum’s paleontology program spent its early years playing catch-up to peer institutions. While other American natural history museums were conducting yearly fossil-collecting expeditions and building collections of one-of-a-kind specimens, the Field Museum’s founding paleontologists struggled for basic resources and recognition within their institution. Today, the department’s public showroom is what Kissell describes as “one of, if not the, most comprehensive explanations of the history of life on Earth in any museum.” It would seem that the Field Museum has found its voice in the pantheon of great natural history museums.

Many thanks to Ashley Hall, Olivier Rieppel, Bill Simpson, and Devin Myers for sharing their time, expertise, and experiences when I was writing this post. Any factual errors are, of course, my own.

AMNH dinosaurs in vintage cartoons

Today I happened upon a pair of wonderful vintage cartoons that simply must be shared. I found them in Edwin Colbert’s The Dinosaur Book: The Ruling Reptiles and Their Relatives, digitized here. The cartoons originally appeared in the New Yorker and the Saturday Evening Post, respectively.

original caption

Original caption: “And here is my first dinosaur – makes me feel like a kid again every time I look at it.”

The cartoons plainly depict the “Brontosaurus” and “Trachodon” (now labeled Apatosaurus and Anatotitan) skeletons at the American Museum of Natural History, and as representations of these mounts, they aren’t bad. At the time of the cartoons’ initial publications in 1939 and 1940, these and dozens of other fossil mounts had been on display at AMNH for over 30 years. They were iconic New York attractions, and the museum had rightly earned itself a reputation as the place to see dinosaurs.

Perhaps it’s unwise to interpret these images too literally, but I can’t help but wonder which version of the AMNH fossil halls the cartoonists intended to depict. Since 1922, the famous mounts had been housed in Henry Osborn’s Great Hall of Dinosaurs, but during the 1930s the dinosaur exhibits underwent a significant expansion. The dinosaurs were reshuffled into two halls, one representing the Jurassic and one the Cretaceous.

The inclusion of a Stegosaurus with “Brontosaurus” and the ceratopsian skulls behind the “Trachodon” lead me to believe these are illustrations of the renovated halls, which would have been brand new at the time. But again, it’s just as likely that the cartoonists only intended to capture the general feel of these famous exhibits.
