The fossil trade is the purchase and sale of fossils. This is at times done illegally with stolen fossils, and important scientific specimens are lost each year. [1] [2] [3] [4] The trade is lucrative, and many celebrities collect fossils. [5]
The fossil trade has attracted criticism from many paleontologists, who regard the private ownership of fossils to be damaging to science.
The auction of the Tyrannosaurus skeleton known as Sue in 1997 for $8.3 million is considered to have caused an increased interest in the fossil trade. [6] According to the head of science and natural history at Christie's, James Hyslop, the market in fossils has been growing consistently since 2007. [7] Due to the increased awareness of the lucrative nature of fossils, many landowners have become more reluctant to work with scientists, preferring to instead offer prospecting rights to the highest bidder. [6] [7]
The international trade in fossils for use in alternative medicine, commonly referred to as "dragon bone", was worth US$700 million annually as of 2010. [8]
Fossil poaching is common in Mongolia. In five years, the United States Immigration and Customs Enforcement seized $44 million worth of smuggled fossils. [9] Fossils from Mongolia and China, which are illegal to export, are often claimed to be from Central Asia. [6]
Fossils sold through the fossil trade are often composites of multiple specimens, not necessarily from a single species, combined to look like one skeleton. [10]
In the United States, it is legal to sell fossils collected on private land. [7] In [[Mongolia]China the export of fossils is illegal. [9] [11] Brazil considers all fossils as federal assets and prohibits their trade since 1942, banned the permanent exports of holotypes and other fossils of national interest in 1990, and requires permits by the Ministry of Science, Technology and Innovation for permanent exports. [12]
The Society of Vertebrate Paleontology, an international association of professional and amateur vertebrate paleontologists, believes that scientifically important fossils—especially but not exclusively those found on public lands—should be held in perpetuity in the public trust, preferably in a museum or research institution, where they can benefit the scientific community as a whole as well as future generations. [13] In the United States, Paleontological Resources Preservation Act. S. 546 and H. R. 2416 were introduced in the US Congress with SVP's full support. [14]
Many commercial fossil collectors and dealers believe that such policies are a breach of their rights. The argument has also been put forth that there are too few professional paleontologists to collect and preserve fossils currently exposed to the elements, and that it is therefore essential that private citizens be allowed to collect them for the sake of their preservation. Eric Scott, the Curator of Paleontology for the San Bernardino County Museum, argues that 1) private citizens and amateur (not for profit) collectors can and do participate frequently in the permitted recovery and preservation of significant vertebrate fossils, and 2) preservation of significant fossils does not require or mandate sale of those fossils. [15] The Society of Vertebrate Paleontology's by-laws state that the society does not condone the trade of scientifically significant vertebrate fossils, except for the purpose of keeping fossils in the public trust. [13]
The illegal export of fossils has increasingly attracted criticism, considered by some a form of science colonialism. As a result, several fossils have been repatriated, and many more are being reclaimed by their countries of origin. [16] [17] Notably, the fossil Ubirajara jubatus , illegally exported from Brazil and deposited in a German museum, was described by a team of German scientists. Their paper has been retracted, and the fossil is to be returned to Brazil. [18] In addition, some of these trafficked fossils are chimeric fabrications to some extent, or may carry less information of their exact origin than fossils extracted following the law. A 2023 description of a turtle fossil deposited in Switzerland revealed the bones present to be from two different genera, Santanachelys and Araripemys , plus unidentifiable fragments. [19] Forgeries like these might make fossils easier to sell to tourists and even to scientists not trained to identify the fakes. [20]
A hoax specimen composed of parts of genuine Yanornis and Microraptor fossils obtained by a museum through the fossil trade was originally interpreted in 1999 as a "missing link" between dinosaurs and birds and planned to be named "Archaeoraptor", but was identified as a hoax before being formally published in a scientific journal. [10]
A Tyrannosaurus skeleton nicknamed "Stan" sold at an auction in 2020 for $31.8 million, a record-setting price. [7]
The skull of a Tyrannosaurus relative called Tarbosaurus bataar illegally exported from Mongolia was purchased by the actor Nicolas Cage for $276,000 in 2007. When contacted by U.S. authorities, Cage voluntarily handed over the specimen for repatriation to Mongolia. [21]
A smuggled skeleton of Tarbosaurus bataar, which is also called Tyrannosaurus bataar, was the subject of the in rem case United States v. One Tyrannosaurus Bataar Skeleton . [6] The fossil was being auctioned in the United States, and was returned to Mongolia in 2013. [22]
The holotype specimen of the dinosaur Halszkaraptor had been obtained through the fossil trade by 2011. Due to its provenance, several scientists initially expressed concern that it was a hoax, but scanning suggests the specimen was not tampered with. [10]
On 18 July 2024 Stegosaurus Apex was auctioned for $44,600,000. It sold eleven times bove pre-sale estimates to American billionaire financier Kenneth Griffin and became the most expensive fossil ever sold. [23]
Albertosaurus is a genus of large tyrannosaurid theropod dinosaur that lived in northwestern North America during the early to middle Maastrichtian age of the Late Cretaceous period, about 71 million years ago. The type species, A. sarcophagus, was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named, although an indeterminate species has been discovered in the Corral de Enmedio and Packard Formations of Mexico. Scientists disagree on the content of the genus and some recognize Gorgosaurus libratus as a second species.
Tyrannosaurus is a genus of large theropod dinosaur. The type species Tyrannosaurus rex, often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods. It lived throughout what is now western North America, on what was then an island continent known as Laramidia. Tyrannosaurus had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the latest Campanian-Maastrichtian ages of the late Cretaceous period, 73.2 to 66 million years ago. It was the last known member of the tyrannosaurids and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event.
Tyrannosauridae is a family of coelurosaurian theropod dinosaurs that comprises two subfamilies containing up to fifteen genera, including the eponymous Tyrannosaurus. The exact number of genera is controversial, with some experts recognizing as few as three. All of these animals lived near the end of the Cretaceous Period and their fossils have been found only in North America and Asia.
Tarbosaurus is a genus of large tyrannosaurid dinosaur that lived in Asia during the Late Cretaceous epoch, about 70 million years ago. It contains the single type species: Tarbosaurus bataar, which is known from the Nemegt Formation of Mongolia, with more fragmentary remains found further afield in the Subashi Formation of China. Tarbosaurus is represented by dozens of fossil specimens, including several complete skulls and skeletons. These remains have allowed studies focusing on its phylogeny, skull mechanics, and brain structure. Further fossil remains have been reported from other geologic formations of Asia, however, these remains are fragmentary and can not be confidentially assigned to Tarbosaurus or the type species.
Deinocheirus is a genus of large ornithomimosaur that lived during the Late Cretaceous around 70 million years ago. In 1965, a pair of large arms, shoulder girdles, and a few other bones of a new dinosaur were first discovered in the Nemegt Formation of Mongolia. In 1970, this specimen became the holotype of the only species within the genus, Deinocheirus mirificus; the genus name is Greek for "horrible hand". No further remains were discovered for almost fifty years, and its nature remained a mystery. Two more complete specimens were described in 2014, which shed light on many aspects of the animal. Parts of these new specimens had been looted from Mongolia some years before, but were repatriated in 2014.
Aublysodon is a genus of carnivorous dinosaurs known only from the Judith River Formation in Montana, which has been dated to the late Campanian age of the late Cretaceous period. The only currently recognized species, Aublysodon mirandus, was named by paleontologist Joseph Leidy in 1868. It is sometimes considered dubious now, because the type specimen consists only of an isolated premaxillary (front) tooth. Although this specimen is now lost, similar teeth have been found in many US states, western Canada, and Asia. These teeth almost certainly belong to juvenile tyrannosaurine tyrannosaurids, but most have not been identified to species level. However, it is likely that the type tooth belongs to one of the species in the genus Daspletosaurus, which was present in contemporary formations, and which matches specific details of the original tooth. The synapomorphies alleged to distinguish the Aublysodontinae, especially lack of serrations on premaxillary teeth could have been caused by tooth wear in life, postmortem abrasion, or digestion. Most other "aublysodontine"-type teeth may be from ontogenetic stages or sexual morphs of other tyrannosaurids.
Alioramus is a genus of tyrannosaurid theropod dinosaurs from the Late Cretaceous period of Asia. It currently contains two species. The type species, A. remotus is known from a partial skull and three foot bones recovered from the Mongolian Nemegt Formation, which was deposited in a humid floodplain about 70 million years ago. These remains were named and described by Soviet paleontologist Sergei Kurzanov in 1976. A second species, A. altai, known from a much more complete skeleton also from the Nemegt Formation, was named and described by Stephen L. Brusatte and colleagues in 2009. Its relationships to other tyrannosaurid genera were at first unclear, with some evidence supporting a hypothesis that Alioramus was closely related to the contemporary species Tarbosaurus bataar. However, the discovery of Qianzhousaurus indicates that it belongs to a distinct branch of tyrannosaurs, namely the tribe Alioramini.
Peter Lars Larson is an American fossil dealer who is head of the Black Hills Institute of Geological Research, which specialises in the excavation and preparation of fossils. He led the team that excavated "Sue", one of the largest and most complete specimens of Tyrannosaurus rex, which was the subject of a legal dispute resulting in its seizure and public auction. In 1996, Larson was convicted of customs violations related to failing to declare money he had brought from overseas, and served 18 months in prison.
Charles Whitney Gilmore was an American paleontologist who gained renown in the early 20th century for his work on vertebrate fossils during his career at the United States National Museum. Gilmore named many dinosaurs in North America and Mongolia, including the Cretaceous sauropod Alamosaurus, Alectrosaurus, Archaeornithomimus, Bactrosaurus, Brachyceratops, Chirostenotes, Mongolosaurus, Parrosaurus, Pinacosaurus, Styracosaurus ovatus and Thescelosaurus.
Tyrannosaurinae is one of the two extinct subfamilies of Tyrannosauridae, a family of coelurosaurian theropods that consists of at least three tribes and several genera. All fossils of these genera have been found in the Late Cretaceous deposits of western North America and east Asia. Compared to the related subfamily Albertosaurinae, tyrannosaurines overall are more robust and larger though the alioramins were gracile by comparison. This subfamily also includes Lythronax, one of the oldest known tyrannosaurid genera, as well as the youngest and most famous member of the group, Tyrannosaurus rex.
Tyrannosaurus is one of the most iconic dinosaurs and is known from numerous specimens, some of which have individually acquired notability due to their scientific significance and media coverage.
The Paleozoological Museum of China is a museum in Beijing, China. The same building also houses the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences. The museum contains exhibition halls with specimens aimed at the public, while the rest of the building is used for research purposes.
Mark Allen Norell is an American vertebrate paleontologist. He is currently the chairman of paleontology and a research associate at the American Museum of Natural History. He is best known as the discoverer of the first theropod embryo and for the description of feathered dinosaurs. Norell is credited with the naming of the genera Apsaravis, Byronosaurus, Citipati, Tsaagan, and Achillobator. His work regularly appears in major scientific journals and was listed by Time magazine as one of the ten most significant science stories of 1993, 1994 and 1996. Norell is both a fellow of the Explorer's Club and the Willi Hennig Society. He was featured in the fourth installment of Miracle Planet—a six-part documentary series that was released in 2005.
Tetrapodophis is an extinct genus of lizard from the Early Cretaceous (Aptian) aged Crato Formation of Brazil. It has an elongated snake-like body, with four disproportionately short limbs.
United States v. One Tyrannosaurus Bataar Skeleton (1:13−cv−00857) is a 2013 United States District Court for the Southern District of New York judgment regarding a requested order from the United States government to seize an imported Mongolian Tarbosaurus skeleton related to smuggling law and the applicability of Mongolian law in the United States.
Bolortsetseg Minjin is a Mongolian paleontologist known for her work in fossil repatriation and dinosaur-themed science outreach. She is a recipient of the WINGS WorldQuest Women of Discovery Award for Earth, National Geographic Explorer, and TEDx speaker. She is the founder of the Institute for the Study of Mongolian Dinosaurs.
Aratasaurus is an extinct genus of basal coelurosaurian theropod dinosaur from the Early Cretaceous (Aptian) Romualdo Formation of Brazil. The genus contains a single species, A. museunacionali, known from a partial right leg. Aratasaurus represents the only tetrapod fossil known from the lower levels of the Romualdo Formation.
Oksoko is a genus of oviraptorid dinosaur from the Late Cretaceous of Asia, that lived in what is now the Nemegt Formation in Mongolia. It includes the type species Oksoko avarsan.
"Ubirajara" is an informal genus of compsognathid theropod that lived during the early Cretaceous period in what is now Brazil. The manuscript describing it was available online pre-publication but was never formally published and, as a consequence, both genus and species name are considered invalid and unavailable. It is known by a single species, "Ubirajara jubatus", recovered from the Crato Formation. It was described as the first Gondwanan non-avian theropod dinosaur discovered with preserved integumentary structures. Such proto-feathers, most likely used for display, include slender monofilaments associated with the base of the neck, increasing in length along the dorsal thoracic region, where they would form a mane, as well as a pair of elongate, ribbon-like structures likely emerging from its shoulders. The taxon was informally named in 2020 in a now-withdrawn in-press academic paper. The description caused controversy due to the fossil having been apparently illegally smuggled from Brazil. In July 2022, Germany agreed to return the fossil to Brazil after a legitimate export permit could not be found. The name "Ubirajara jubatus" was removed from ZooBank in November 2022, which means it no longer has any nomenclatural significance.
