At some point in the 1870s or possibly the very early 1880s, photographer James F. Jarvis set up his camera and array of equipment at the Smithsonian Castle and took photographs of the institution’s mounted skeleton of Hadrosaurus foulkii, a dinosaur from the Cretaceous period (about 146 to 66 million years ago). From the glass negatives he prepared at the Smithsonian, Jarvis produced a stereoview or stereograph featuring the Hadrosaurus. (Stereoviews or stereographs – cards whose dual mounted photographs generate a 3-D image when viewed through a stereoscope – have been considered previously on this blog.)
I recently added a copy of this stereoview to my collection. The full face of this stereoview and a closeup of one of the two pictures are shown below. The Hadrosaurus is prominent in the foreground, facing into the picture. In front of it is a large Himmalayan tortoise shell from the Miocene epoch (about 23 to 5 million years ago), and in front of the tortoise is the restoration of an Irish elk, the Pleistocene epoch giant deer that went extinct some 11,000 years ago.
Originally, I thought it would be relatively easy to compose a posting on the subject of this specific stereoview. Clearly, I had no clue about the richly convoluted the history of this mounted skeleton of Hadrosaurus. Nor did I recognize that these photographs speak to a contemporary debate about the display of “fake” skeletons by natural history museums. (Some of the sources I consulted are identified in the text; most are included in the discussion of sources at the end.)
Initially, though, I wanted to place a date on the stereoview, well, actually, the taking of the negative. The Smithsonian has produced a fascinating webpage on stereoviews of the institution. According to the information appearing there, beginning in 1874, the Hadrosaurus skeleton was on display in the Main Hall of the Smithsonian Building, a structure usually referred to as the Castle. Then, in 1882, along with other skeletons and specimens, the Hadrosaurus was moved to the Smithsonian’s National Museum building. This Jarvis stereoview shows the Castle’s Lower Main Hall looking east, which means it had to have been taken between 1874 and 1882. Unfortunately, that doesn’t really narrow it down very much.
What was the source of the skeleton? The fossilized bones of a giant creature had been discovered in 1858 in Haddonfield, New Jersey, by Philadelphia lawyer and fossil hunter William Parker Foulke. Foulke called in Joseph Leidy, a professor of anatomy at the University of Pennsylvania and curator at the Academy of Natural Sciences in Philadelphia, who identified them as coming from a dinosaur, a term that had been coined by English paleontologist and biologist Richard Owen in the early 1840s. This was the most complete dinosaur skeleton that had ever been found anywhere. Leidy named the dinosaur Hadrosaurus foulkii (the genus name means “bulky lizard” and the species name recognizes Foulke).
A decade later, the English anatomist, scientific illustrator, and sculptor Benjamin Waterhouse Hawkins came on the scene, having traveled to the U.S. to create a dinosaur display for a new museum in New York City. After consulting Leidy about the New York display, he undertook the task of mounting the Hadrosaurus skeleton for the Academy of Natural Sciences. With assistance from Leidy and one of Leidy’s students, Edward Drinker Cope, Hawkins created a mounted dinosaur skeleton using plaster casts of the bones at hand and plaster reconstructions, based on educated guesses, of those that were missing. This was the first mounted dinosaur skeleton ever produced and, as we all know, this kind of display was destined to become a staple of natural history museums worldwide.
The skeleton went on display at the Academy in late 1868, attracting throngs of visitors, so many that officials of the Academy took steps to reduce the number of visitors, curtailing the days it was open to the public and charging admission. The success of the display apparently was not lost on other institutions that then sought to obtain their own copies; Hawkins produced several. According to Richard C. Ryder, the Smithsonian received a copy sometime between March 1874 and mid 1875.
After being displayed in the Smithsonian Castle, the Smithsonian’s Hadrosaurus was moved in 1882 to the National Museum building where it remained until perhaps 1893 or 1894. Ryder says that it was then sent to the Field Museum of Natural History in Chicago, “only to be discarded when the museum moved to new quarters a decade later.”
Breathtakingly innovative for its time, Hawkins’ Hadrosaurus skeletons got some things right, and missed the boat on some others. For instance, the posing of the Hadrosaurus in an upright, bipedal position reflected Leidy’s accurate understanding of the dinosaur. But, the three-pronged supporting position of the hind legs and the tail, giving the creature a kangaroo-like appearance, was ultimately disproven by subsequent research. The drawing below depicts current understanding of the positioning and use of the tail (the picture comes from the New Jersey Geological Survey). The Academy’s clutch of Hadrosaurus bones lacked a skull, so Hawkins made one based on the head of an iguana lizard, a creative though erroneous solution to the problem.
One passing comment on Leidy’s student, Edward Drinker Cope. Cope became one of the country’s foremost paleontologists and engaged in the famous no-holds-barred competition against Othniel Charles Marsh to find dinosaur fossils – the so-called Bone Wars. This conflict had a Hadrosaurus connection. Before the battle royal began, the two men spent what paleontologist Michael Novacek describes as “a friendly week together poking around Leidy’s old Haddonfield quarry for hadrosaur bones.” Hoag Levins, in an article on his great website Finding the World’s First Dinosaur Skeleton: Hadrosaurus foulkii, asserts that the Cope-Marsh conflict had its roots in this friendly time together. Cope generously introduced Marsh to the managers of different pits from which dinosaur bones were being collected. The falling out occurred when Cope learned that, shortly after they left the area, Marsh returned alone, money in hand, to bribe the managers to send him bones and word of what they had found.
Hawkins’ Hadrosaurus skeleton also has some bearing on a debate of sorts that involves natural history museums today. Earlier this year, “Thomas H. Benton” (the pen name of William Pannapacker), a professor of English at Hope College, published a piece in The Chronicle of Higher Education entitled Getting Real at Natural-History Museums (July 1, 2010) in which he takes these museums to task for succumbing to the entertainment bug and for mounting displays that contain “fakes.” Venturing into the Academy of Natural Sciences in Philadelphia with his daughter in search of the real dinosaur skeletons he remembered from his youth, he was dismayed to discover only replicas. He asserts
Natural-history museums like the [Academy of Natural Sciences] emerged to provide exhibits that were reliably authentic and that could instruct the public and build the credibility of science in a period, like our own, in which pseudoscience had a strong hold on the general imagination. Of course, the replicas in natural-history museums, unlike [P.T.] Barnum’s humbugs, present authentic science, but, over the last few generation, museums have become more willing to use substitutes in place of real artifacts. It seemed like a good idea at the time. . . .
You could say that a fake skeleton educates as well as a real one, and it surely looks as good for publicity purposes. But one of the fundamental attractions of natural-history museums – and museums in general – is the aura of authenticity and the power they have to inspire the imagination, particularly for children, in an era that is increasingly characterized by the virtual and the simulated. That was not true when fossil replicas were first introduced – the changes were made with the best of intentions – but it is surely the case now.
Frankly, I am always suspicious of people who argue that there was once a “golden age” and that we’ve lost our way. Too often that “golden age” proves to have been a mirage, the reality being nothing like what was remembered. Clearly, that's the case in this instance.
A wonderful response to “Benton” was penned by Chris, a museum curator, on his blog Prerogative of Harlots (July 26, 2010). He observes, “When Benton refers to fakes, he’s actually taking about casts – specifically the cast dinosaur skeletons that many museums exhibit in their galleries.” Why do they do that? For one thing, there are very few complete fossil skeletons. Most are exceedingly incomplete. So even a skeleton of an individual specimen that includes real bones will include many replicas of bone. Chris points out that the dinosaur “Benton” remembers from his youth at the Academy was a composite, not the “real” thing. Chris describes the precision behind the creation of casts, a process producing something that is
as close to the fossil as it’s possible to get without actually owning it. Casts are heavily used in paleontology because of the scarcity of fossil specimens – they are exchanged between museums and sent out on loan to researchers. We assign them catalog numbers and treat them in the same way as we would treat any museum specimen.
He argues, persuasively in my mind, that the answer to the question “Is it real?” when standing before a dinosaur skeleton cast is
Absolutely, in the sense that there was once an animal that looked like this, we have the bones to prove it, and this exhibit specimen could not have been made without those bones.
Hawkins’ Hadrosaurus foulkii itself constitutes another strong response to “Benton.” From the very outset of museums displaying mounted dinosaur skeletons, they were real only in the sense that Chris described, not in the way “Benton” misremembered from his childhood and before. Then and now, they draw crowds and inspire the imagination, regardless of whether this or that bone is rock or a cast.
One final small note, Hawkins is tied to the Hadrosaurus stereoview in another way; it’s his restoration of an Irish elk appearing in the background.
The Academy of Natural Science has some useful information on its website for the exhibit about Hadrosaurus foulkii that it mounted in 2009.
Richard C. Ryder wrote a very interesting piece on dinosaurs in stereoviews entitled Dinosaurs Through the Stereoscope, Stereoworld, March/April 1985.
