Tyrannosaurus rex isn’t only a king to paleontologists — the dinosaur more and more reigns over the world of artwork auctions. A virtually full skeleton often known as Stan the T. rex smashed information in October 2020 when a bidding conflict drove its value to $31.8 million, the best ever paid for any fossil. Before that, Sue the T. rex held the highest spot; it went for $8.3 million in 1997.
That sort of publicity — and cachet — implies that T. rex’s worth is sky-high, and the dinosaur continues to have its enamel firmly sunk into the public sale world in 2022. In December, Maximus, a T. rex cranium, would be the centerpiece of a Sotheby’s public sale in New York City. It’s anticipated to promote for about $15 million.
Another T. rex fossil named Shen was anticipated to promote for between $15 million and $25 million at a Christie’s public sale in Hong Kong in late November. However, the public sale home pulled it over issues in regards to the variety of reproduction bones used within the fossil.

“These are astronomical sums of money, really surprising sums of money,” says Donna Yates, a criminologist at Maastricht University within the Netherlands who research high-value collectibles.
Stan’s ultimate value “was completely unexpected,” Yates says. The fossil was initially appraised at about $6 million — nonetheless a really giant sum, although nothing like the ultimate tally, which was the results of a three-way bidding conflict.
But the staggering quantities of cash T. rex fossils now fetch at public sale can imply an enormous loss for science. At these costs, the general public establishments which may attempt to declare these glimpses into the deep previous are unable to compete with deep-pocketed non-public consumers, researchers say.
One cause for the sky-high costs could also be that T. rex fossils are more and more being handled extra like uncommon artistic endeavors than bits of scientific proof, Yates says. The bones may as soon as have been purchased and offered at dusty “cowboy fossil” dealerships. But these days these fossils are on show in shiny gallery areas and are being appraised and marketed as uncommon objets d’artwork. That’s interesting to collectors, she provides: “If you’re a high-value buyer, you’re a person who wants the finest things.”
But fossils’ true worth is the data they maintain, says Thomas Carr, a paleontologist at Carthage College in Kenosha, Wis. “They are our only means of understanding the biology and evolution of extinct animals.”
Keeping fossils of T. rex and different dinosaurs and animals in public repositories, reminiscent of museums, ensures that scientists have constant entry to check the objects, together with with the ability to replicate or reevaluate earlier findings. But a fossil offered into non-public or business palms is topic to the whim of its proprietor — which implies something may occur to it at any time, Carr says.

“It doesn’t matter if [a T. rex fossil] is bought by some oligarch in Russia who says scientists can come and study it,” he says. “You might as well take a sledgehammer to it and destroy it.”
A need for one’s personal T. rex
There are solely about 120 recognized specimens of T. rex on the earth. At least half of them are owned privately and aren’t out there to the general public. That loss is “wreaking havoc on our dataset. If we don’t have a good sample size, we can’t claim to know anything about [T. rex],” Carr says.
For instance, to have the ability to inform all of the ways in which T. rex males differed from females, researchers want between 70 and 100 good specimens for statistically important analyses, an quantity scientists don’t presently have.
Similarly, scientists know little about how T. rex grew, and finding out fossils of kids may assist (SN: 1/6/20). But solely a handful of juvenile T. rex specimens are publicly out there to researchers. That quantity would double if non-public specimens had been included.
Museums and educational establishments usually don’t have the sort of cash it takes to compete with non-public bidders in auctions or any such aggressive gross sales. That’s why, within the month earlier than Stan went up for public sale in 2020, the Society for Vertebrate Paleontology, or SVP, wrote a letter to Christie’s asking the public sale home to think about limiting bidding to public establishments. The hope was that this could give scientists a combating probability to acquire the specimens.
But the request was ignored — and sadly might have solely elevated publicity for the sale, says Stuart Sumida, a paleontologist at California State University in San Bernardino and SVP’s present vice chairman. That’s why SVP didn’t challenge a public assertion this time forward of the auctions for Shen and Maximus, Sumida says, although the group continues to strongly condemn fossil gross sales — whether or not of enormous, dramatic specimens or much less well-known creatures. “All fossils are data. Our position is that selling fossils is not scientific and it damages science.”
Sumida is especially appalled at statements made by public sale homes that counsel the skeletons “have already been studied,” an try to reassure researchers that the information contained in that fossil gained’t be misplaced, no matter who purchases it. That’s deeply deceptive, he says, due to the necessity for reproducibility, in addition to the always-improving improvement of latest evaluation methods. “When they make public statements like that, they are undermining not only paleontology, but the scientific process as well.”
And the excessive costs earned by Stan and Sue are serving to to drive the market skyward, not just for different T. rex fossils but additionally for much less well-known species. “It creates this ripple effect that is incredibly damaging to science in general,” Sumida says. Sotheby’s, for instance, auctioned off a Gorgosaurus, a T. rex relative, in July for $6.1 million. In May, a Deinonychus antirrhopus — the inspiration for Jurassic Park’s velociraptor — was offered by Christie’s for $12.4 million.
Protecting T. rex from collectors
Compounding the issue is the truth that the United States has no protections in place for fossils unearthed from the backyards or dusty fields of personal landowners. The U.S. is residence to only about each T. rex skeleton ever discovered. Stan, Sue and Maximus hail from the Black Hills of South Dakota. Shen was present in Montana.
As of 2009, U.S. legislation prohibits amassing scientifically worthwhile fossils, significantly fossils of vertebrate species like T. rex, from public lands with out permits. But fossils discovered on non-public lands are nonetheless thought-about the landowner’s private property. And landowners can grant digging entry to whomever they need.
Before the invention of Sue the T. rex (SN: 9/6/14), non-public homeowners usually gave scientific establishments free entry to hunt for fossils on their land, says Bridget Roddy, presently a researcher on the authorized information firm Bloomberg Law in Washington, D.C. But within the wake of Sue’s sale in 1997, researchers started to must compete for digging entry with business fossil hunters.
These hunters can afford to pay landowners giant sums for the proper to dig, or perhaps a share of the earnings from fossil gross sales. And many of those business sellers promote their finds at public sale homes, the place the fossils can earn excess of most museums are capable of pay.
Lack of federal protections for paleontological sources discovered on non-public land — mixed with the massive out there provide of fossils — is a scenario distinctive to the United States, Roddy says. Fossil-rich international locations reminiscent of China, Canada, Italy and France think about any such finds to be below authorities safety, a part of a nationwide legacy.
In the United States, seizing such supplies from non-public landowners — below an eminent area argument — would require the federal government to pay “just compensation” to the landowners. But utilizing eminent area to typically defend such fossils wouldn’t be financially sustainable for the federal government, Roddy says, not least as a result of most fossils dug up aren’t of nice scientific worth anyway.
There could also be different, extra grassroots methods to at the least higher regulate fossil gross sales, she says. While nonetheless a legislation pupil at DePaul University in Chicago, Roddy outlined a few of these concepts in an article revealed in Texas A&M Journal of Property Law in May.
One possibility, she suggests, is for states to create a selective gross sales tax connected to fossil purchases, particularly for consumers who intend to maintain their purchases in non-public collections that aren’t available to the general public. It’s “similar to if you want to buy a pack of cigarettes, which is meant to offset the harm that buying cigarettes does to society in general,” Roddy says. That technique may very well be significantly efficient in states with giant public sale homes, like New York.
Another chance is to mannequin any new, expanded fossil preservation legal guidelines on present U.S. antiquities legal guidelines, meant to protect cultural heritage. After all, Roddy says, fossils aren’t simply bones, however they’re additionally a part of the human story. “Fossils have influenced our folklore; they’re a unifier of humanity and culture rather than a separate thing.”
Though fossils from non-public lands aren’t protected, many states do impose restrictions on searches for archaeological and cultural artifacts, by requiring these searching for antiquities to revive excavated land or by fining the excavation of sure antiquities with out state permission. Expanding these restrictions to fossil searching, maybe by requiring state approval via permits, may additionally give states the chance to buy any important finds earlier than they’re misplaced to personal consumers.
Preserving fossils for science and the general public
Such protections may very well be an enormous boon to paleontologists, who might not even know what’s being misplaced. “The problem is, we’ll never know” all of the fossils which can be being offered, Sumida says. “They’re shutting scientists out of the conversation.”
And on the subject of dinosaurs, “so many of the species we know about are represented by a single fossil,” says Stephen Brusatte, a paleontologist on the University of Edinburgh. “If that fossil was never found, or disappeared into the vault of a collector, then we wouldn’t know about that dinosaur.”
Or, he says, typically a very full or fantastically preserved dinosaur skeleton is discovered, and with out it, “we wouldn’t be able to study what that dinosaur looked like, how it moved, what it ate, how it sensed its world, how it grew.”
The level isn’t to place restrictions on amassing fossils a lot as ensuring they continue to be in public view, Brusatte provides. “There’s nothing as magical as finding your own fossils, being the first person ever to see something that lived millions of years ago.” But, he says, distinctive and scientifically invaluable fossils reminiscent of dinosaur skeletons needs to be positioned in museums “where they can be conserved and studied and inspire the public, rather than in the basements or yachts of the oligarch class.”
After its record-breaking sale, Stan vanished for a yr and a half, its new homeowners a thriller. Then in March 2022, information surfaced that the fossil had been purchased by the United Arab Emirates, which acknowledged it intends to put Stan in a brand new pure historical past museum.
Sue, too, is on public view. The fossil is housed at Chicago’s Field Museum of Natural History, because of the pooled monetary sources of the Walt Disney Corporation, the McDonald Corporation, the California State University System and others. That’s the sort of cash it took to get the best bid on a T. rex 25 years in the past.
And these costs solely appear to be going up. Researchers obtained fortunate with Sue, and probably Stan.
As for Shen, the fossil’s destiny stays in limbo: It was pulled from public sale not attributable to outcry from paleontologists, however over issues about mental property rights. The fossil, at 54 p.c full, might have been supplemented with a polyurethane forged of bones from Stan, in keeping with representatives of the Black Hills Institute of Geological Research in Hill City, S.D. That group, which found Stan, retains a copyright over the skeleton.
In response to these issues, Christie’s pulled the lot, and now says that it intends to mortgage the fossil to a museum. But this transfer doesn’t reassure paleontologists. “A lot of people are pleased that the sale didn’t go through,” Sumida says. “But it sort of just kicks the can down the road.… It doesn’t mean they’re not going to try and sell it in another form, somewhere down the road.”
Ultimately, scientists merely can’t rely on each vital fossil discovering its option to the general public, Carr says. “Those fossils belong in a museum; it’s right out of Indiana Jones,” he says. “It’s not like they’re made in a factory somewhere. Fossils are nonrenewable resources. Once Shen is gone, it’s gone.”
