The Million-Dollar Dinosaur Scandal

Fossils are priceless. I mean that in both senses: They are invaluable clues about vanished lives, and their worth should never be measured in dollars. But Eric Prokopi made quite a bit of money dealing fossils and, as it turns out, brazenly smuggling them. He recently pled guilty to conspiracy, making false statements to customs officials, illegally importing fossils into the United States, and fraudulent transfer of dinosaur bones. He is set to be sentenced in April and faces up to 17 years in prison. Prokopi’s string of fossil offenses was finally exposed in the past few months because of a dinosaur that was almost sold for $1 million. His story is one of the most egregious cases of dinosaur rustling in recent years, and it shows just how corrupt and harmful to science the fossil market can be.

The ugly tale began when Texas-based Heritage Auctions put out a catalog for a May 20 event in New York City. The lots included an ankylosaur skull, a troodontid skeleton, and the hyped star of the sale, a “75 percent complete” Tarbosaurus bataar skeleton. This tyrannosaur, which roamed Mongolia about 70 million years ago, was comparable in size and ferocity to its famous cousin Tyrannosaurus rex. (The auction ads took advantage of a taxonomic disagreement among paleontologists and called the fossil Tyrannosaurus bataar, but I’m in the camp that believes these dinosaurs should be kept in distinct genera.)

It seemed the dinosaur was going to slip away into a private collection. For years, paleontologists have watched as significant specimens have gone from field sites to wealthy fossil enthusiasts. Some researchers have even had dinosaurs stolen right out from under them, finding their carefully-excavated quarries turned to shambles littered with cigarette butts, booze bottles, and broken bones.

There are legitimate dealers who abide by laws on collecting, importing, and selling fossils, but you’ll always find questionable specimens from China, Brazil, Morocco, and other locations if you visit a fossil or mineral show. What’s on display is only the tip of the iceberg. The real action at places like the annual Tuscon Gem and Mineral Show is behind closed doors in private hotel rooms, where sellers save their fanciest—and most illicit—deals for customers they feel they can trust. Countries around the world have passed laws that make it difficult to sell dinosaurs and other fossils legally, but dealers keep finding new ways around the laws, and the black market thrives. Even dealers who keep their noses clean almost never contribute anything to science—they treat fossils as petrified postage stamps to be hoarded, traded, and sold off.

Whoever had collected the Tarbosaurus had stripped away almost everything of scientific importance about the animal: how the bones were scattered in the rock where they were found, what preparations were used to clean and reassemble the skeleton, what other fossils were in the same or nearby layers. But paleontologists were certain that the dinosaur came from the Cretaceous rock of Mongolia. This is the only place in the world where Tarbosaurus skeletons are found in great numbers, and the dinosaur’s off-white bones were the same color as other dinosaur remains found in the Gobi Desert.

There was no reasonable doubt that the Tarbosaurus had been stolen. China and Mongolia strictly regulate who is allowed to launch dinosaur expeditions and collect fossils and where those specimens must be reposited. There was no legal route by which the dinosaur could have ended up in a New York City auction. Days before it was set to be sold, paleontologists and the president of Mongolia objected to the auction. Paleontologist Mark Norell of the American Museum of Natural History, who has worked extensively in Mongolia, pointed out that the dinosaur must be an illicit specimen from the Gobi Desert. According to Mongolian heritage laws, any recovered bones must ultimately rest within an approved Mongolian institution. (The AMNH itself made an international faux pas when it auctioned off a Mongolian dinosaur egg in 1924.)

Heritage Auctions pooh-poohed the concerns and affirmed that the auction house trusted the dealer it was working with. Greg Rohan, president of Heritage Auctions, steadfastly defended the auction, whining that it was too close to the date of the auction to do anything about the complaints of the Mongolian government and concerned researchers. Lawyers working in concert with the Mongolian government entered the kerfuffle and demanded that the auction be halted until the provenance of the skeleton could be settled.

The auction went ahead as scheduled. In the middle of the bidding, a lawyer announced that he had on the phone a judge who had issued an order against the sale. Even this last-minute tactic didn’t stop the bidding. The final price of the Tarbosaurus was just over $1 million.

Fortunately, the unknown buyer couldn’t simply walk off with the dinosaur. Investigations continued, now with the begrudging assistance of Heritage Auctions, and Norell and other paleontologists confirmed that the tyrannosaur must have been uncovered in Mongolia. More than that, what was billed as a nearly complete individual animal turned out to be made of several different dinosaurs. (Surprise, surprise, the smuggler wasn’t honest about his wares. Many dinosaurs that appear at auction houses are not as complete or well-preserved as they might appear to the untrained eye.)

The investigation revealed that the origin of the bones had been obscured by shipping them from Great Britain to the United States labeled as assorted reptile fossils. By June 22, Prokopi was identified as the dealer, and the skeleton had been seized by the United States government. Though it is still bound by red tape, the dinosaur soon may be returned home to Mongolia.

Sadly, the other dinosaur fossils in the same auction were sold off without much attention. Still, inspired by the controversy, paleontologist Paul Barrett of the Natural History Museum in London halted the auction of a Tarbosaurus leg at Christie’s that was scheduled for about the same time. Barrett had noticed the leg in the window of the South Kensington auction house and contacted Christie’s, which informed the owner that the specimen was questionable. The lot was pulled from sale, and, Barrett says, is presumably still with its U.K. owner.

Such simple actions may help deter illegal and illicit fossil sales. “I'd say it's just a case of staying vigilant, helping auction houses know about the legality of the specimens they handle, and in some cases attempting to persuade owners of their responsibilities,” Barrett told me. Private owners may not even know where their prize came from, how it was collected, or whether any laws were broken in the process. Repatriation, however, is hard to enforce. Unless there’s some kind of illegal activity, such as a customs violation, Barrett said, where an illicit fossil ends up depends on the whim of the owners.

Prokopi wasn’t so lucky. His defense crumbled as it became clear through early court proceedings that he had tried to hide the dinosaur by lying about what kind of bones he had and claiming the fossils were found and collected legally in England. Customs violations were the smuggler’s undoing.

Following his guilty plea, details about Prokopi’s dealings have started to trickle out. The Tampa Bay Times characterized him as a passionate Indiana Jones who followed his dream. What the sympathetic reporter didn’t understand, though, was that Prokopi actively undermined legitimate paleontology. He fueled a black market that robs specimens from science and the public alike.

We can’t learn anything from a Tarbosaurus that stands in a millionaire’s mansion. And contrary to what you might expect, relatively abundant dinosaurs like Tarbosaurus are important exactly because so many have been found. By comparing multiple specimens, even cutting up fossil bones to get a look at the microstructure of bone or drilling geochemical samples from them, researchers can get a better idea of how dinosaurs grew up, how they varied as individuals, and other intricate details about dinosaur biology. Dinosaur bones are not just static objects to be left on the shelf. The more individuals of a species we have, the better we can reconstruct how they lived and accurately portray the evolution and biology of these animals, whether in museum displays or movies.

Dinosaurs that make their way to the auction block are often showpieces, sold without information. The geologic context of a dinosaur—which is destroyed by fossil thieves and smugglers—allows paleontologists to properly identify the age of the animal, and the position of the bones in death can illustrate how it died or what happened to the body after death. As paleontologist Jack Horner put it in his book Dinosaur Lives, “A dinosaur out of context is like a character without a story. Worse than that, the character suffers from amnesia.”

The international market for unusual fossil specimens damages science in other ways as well. Some sellers create forgeries and chimeras. The croc-snouted dinosaur Irritator got its name because a fossil dealer glued extraneous bones to the dinosaur’s skull to make it look more complete than it was. Paleontologists were able to catch that fake, but researchers can be fooled by fancy fossils with murky backstories, as in the case of a fossil cheetah skull described in a PNAS paper that was retracted last year. The skull was artificially enhanced, and the lack of locality data meant that no one could be sure where it fit in the big picture of cat evolution.

Even the venerable National Geographic gave undue attention to a faked fossil. (I should mention that I blog about paleontology for the magazine’s Phenomena website.) In the fall of 1999, the magazine heralded “Archaeoraptor” as a significant evolutionary stage in the evolution of birds from dinosaurs. The animal seemed to exhibit a mixture of traits from early birds and their dinosaur predecessors, fitting within the pattern of authentic feathered dinosaurs that were just beginning to be described in the peer-reviewed literature.

But the origins and identity of “Archaeoraptor” were shady from the start. The fossil had been purchased for $80,000 from a commercial dealer at the Tucson Gem and Mineral Show and was supposed to go to the tiny Dinosaur Museum in Blanding, Utah, run by artists Stephen and Sylvia Czerkas. They reached out to professional paleontologist Phil Currie, who contacted National Geographic to suggest a story. It quickly became clear that the fossil had been illegally exported from China. Even worse, further preparation of the slab and CT scans by fossil imaging expert Tim Rowe suggested that “Archaeoraptor” was a composite of at least two different fossils.

The Czerkases denied that their prize could be a fake, going so far as to submit manuscripts about the fossil to Nature and Science to legitimize the find, but the journals wouldn’t touch the hot fossil. National Geographic went ahead with its publication and press conference. Shortly after, paleontologist Xu Xing, an expert on feathered dinosaurs, confirmed that “Archaeoraptor” was pieced together from different animals, later identified as including the nonavian dinosaur Microraptor and the early bird Yanornis.

A few months later, after an internal investigation, National Geographic recanted and admitted that “Archaeoraptor” was a fraud. The magazine’s confession was admirable, but the hype around the controversial chimera gave ammunition to creationists and those who stubbornly insist that birds cannot be dinosaurs. Authentic, well-studied fossils have confirmed over and over again that birds are just one kind of dinosaur, but fundamentalists still trot out “Archaeoraptor” to insist that the scientific community cannot be trusted. Black market fossils can hurt science in an unfortunate array of ways.

No one benefits from the sale of fossils except the dealer. The bylaws of the Society of Vertebrate Paleontology hold its members to a professional standard: “The barter, sale, or purchase of scientifically significant vertebrate fossils is not condoned, unless it brings them into or keeps them within a public trust.” Even then, many professional paleontologists feel unsettled by high-profile sales that inspire unethical collectors to obtain and sell off important fossils. The controversial, overhyped fossil primate fossil Darwinius—known to the public as “Ida” and presented at the time as The Link to our primate ancestry—was sold to the Natural History Museum in Oslo, Norway for a reported $750,000. Prehistoric primate expert Elwyn Simons and other paleontologists explained in Nature that “such objectionable pricing and publicity can only increase the difficulty of scientific collecting by encouraging the commercial exploitation of sites and the disappearance of fossils into private collections … We strongly believe the fossils should not have any commercial value.”

I understand the urge to have a dinosaur to call your own. I’ve got one myself: a skull of the long-necked, stout Jurassic sauropod Apatosaurus. But mine is a cast, which I found at the estate sale of the late Utah paleontologist James Madsen, Jr. Such alternatives let dinosaur fans have a piece of prehistory without depriving science. Indeed, reconstruction exports like Robert Gaston create and sell beautiful, lightweight casts of scientifically accurate dinosaur skeletons that are easier to mount and less expensive than real fossils.* Museums rely on casts for their own displays, after all, and museum-quality reproductions should satisfy the need of anyone who loves dinosaurs and the science of paleontology.

When I initially objected to the Tarbosaurus auction back in May, many readers responded that museums should fend for themselves. This argument ignores the perilous state of many museums and fundamentally misunderstands how modern paleontology is done. What is happening to the home of the $8 million T. rex named Sue is a sad example of why museums can’t, and shouldn’t, pay through the nose for questionable dinosaurs.

Sue had a twisted backstory of her own, with commercial paleontologists from the Black Hills Institute, landowner Maurice Williams, and even the federal government disputing ownership. Ultimately, after drawn-out legal disputes, Williams was granted ownership of the dinosaur, and he put it up for auction before Sotheby’s auction house. With the help of deals made with Disney, McDonald’s, and other sources, Chicago’s Field Museum of Natural History acquired the dinosaur. As the institution recently made clear, though, they’re no longer in any state to purchase fossils.

The Field Museum is so strapped for cash that administrators are threatening to scrap various branches of scientific research. They plan to save the museum by cutting its heart out—a museum is not really a museum without responsibly-kept collections and an active research program. Under such circumstances, even major research institutions like the Field can’t possibly compete with rich private buyers. More than that, trying to outbid wealthy buyers for improperly-collected specimens would be a stupid move for any self-respecting institution, especially since $1 million would allow a museum’s paleontology crew to spend several seasons finding and collecting new dinosaurs.

Even when private collectors act in good faith, looted dinosaurs can still cause headaches for researchers. In 2009, University of Chicago paleontologist Paul Sereno and colleagues described Raptorex kriegsteini, which appeared to be a tiny prototype of the famous Tyrannosaurus rex body plan. They based the description on a skeleton purchased from a dealer by private collector Henry Kriegstein. When Kriegstein approached Sereno about identifying the fossil, Sereno realized that the new dinosaur species had been illegally collected and would have to be returned to China. Kriegstein agreed, and in exchange, Sereno named the dinosaur after Kriegstein’s parents. Through this arrangement, Raptorex was brought into the scientific literature and public trust, and was sent to a museum in Inner Mongolia, China.

The fate of Raptorex sounds like a happy ending, but a subsequent analysis of the same dinosaur highlighted how problematic commercially-collected specimens are. Museum of the Rockies paleontologist Denver Fowler and colleagues suspect that the skeleton of Raptorex is actually a juvenile Tarbosaurus. Anecdotal evidence and the scant amount of geologic information suggest that the dinosaur came from Mongolia rather than China. If we don’t know where fossils came from, how can we return fossils to their home countries, much less understand what the fossils mean?

Cases such as Prokopi’s, the illegal activities of commercial fossil hunter Nathan Murphy, and the legal tangles around “Tinker” the Tyrannosaurus underscore the shady nature of commercial collecting. And during a time when many museums are financially squeezed, the insistence of commercial collectors that they’d really like to sell specimens to research institutions where the fossils will be properly conserved and used to communicate science to the public—they really do claim this is their goal—is disingenuous. Rather than assisting science, commercial collectors are robbing everyone of specimens by making them accessible only to those with deep pockets.

Commercial collectors could do the right thing by working with professional paleontologists to responsibly excavate fossils for public institutions, with a small finder’s fee and rights to produce casts going to the commercial dealer. Of course, this would require private landowners and commercial collectors to stop seeing dollar signs made out of dinosaur bones. After the sale of Sue, Ida, and other high-profile fossils, researchers will continue to struggle against those who seek to turn petrifactions into profit.

Commercial collectors argue that, if they don’t act, many fossils may be destroyed due to erosion. And it’s true that there are not enough professional paleontologists to excavate every dinosaur that starts peeking out of the ground. But it would be better to let a Triceratops skull fall to pieces than have that specimen mangled by amateurs who ignore basic scientific data collection and then try to sell that skull to private buyers, hiding it away from researchers and fueling a market that makes significant specimens inaccessible. There is an opportunity cost to digging up one dinosaur and not another, but it’s better to lose a few in the process of rigorous science than to wind up with a jumble of dinosaurs of questionable provenance.
