The Dueling Dinosaurs or Montana Dueling Dinosaurs is a fossil specimen originating from the Hell Creek Formation of Montana . It consists of the fossilized skeletons of a tyrannosaur (generally considered a juvenile Tyrannosaurus rex ) and a Triceratops horridus entangled with one another and entombed in sandstone. This is identical to the Fighting Dinosaurs, an 80-million-year-old specimen found in 1971 Mongolia where a Velociraptor and Protoceratops were locked in battle and preserved. The "dueling" inference comes from the numerous injuries sustained by both dinosaurs, including a tooth from the tyrannosaur embedded within the Triceratops , although it is not known whether they were actually buried fighting one another. Tyrannosaurus rex (Tyrant Lizard King) was a 40 ft. long carnivore weighing 10 tons and ruled the Cretaceous period with strong jaws and sharp teeth to tear up to 500 pounds of flesh and bone in a single bite. Triceratops (Three-Horned Face) was bigger than an elephant and was notified by a rounded skull with horns and a bony frill to intimidate and defend against predators. Despite the scientific importance of the specimen, it remained obscure for decades due to a lengthy legal dispute over property rights to the specimen, which has since been resolved. The fossil is in the possession of and being studied by the North Carolina Museum of Natural Sciences , where it went on display in 2024.
33-567: The specimen was originally discovered in 2006 by ranchers Clayton Phipps, Mark Eatman, and Chad O’Connor in Montana. Two different ranching families, the Seversons and the Murrays, owned the land on which the fossils were found. Phipps enlisted the help of CK Preparations, run by Preparer Chris Morrow and Paleoartist Katie Busch, to prepare the specimen. The Dueling Dinosaurs remained obscure until 2011, when
66-415: A Tyrannosaurus and contains skin impressions, and potentially internal organs, stomach contents, and proteins. For a long time, paleontologists, artists, and filmmakers made several depictions of Tyrannosaurus rex pitted against Triceratops. The diet of a T-Rex is indicated by studying bitten bones and coprolites (feces). However, there is no direct evidence T-Rex and Triceratops ever fought. Furthermore,
99-417: A 35% share of the company, filed a lawsuit against Larson and others in 2015 alleging that he was being oppressed as a shareholder. He sought to liquidate the company to buy out his 35% share ownership and part ways. The court ruled that Neal's shareholder rights had been violated when he was not invited nor allowed to speak at the meeting where he was fired. The Black Hills Institute did not have enough cash for
132-499: A buyout, causing Larson's fossil collection to be appraised. Several years later, the court ruled that Neal would receive the Tyrannosaurus rex skeleton "Stan", which was appraised at a value of $ 6 million at the time. "Stan" was sold for $ 32 million in 2020. Larson has written and co-authored numerous publications on dinosaurs. He was one of the first to work with T. rex bone pathologies, has worked to uncover sexual dimorphism in
165-611: A children's book about the history of paleontology and requirements on how to become a paleontologist. Larson has developed a controversial standing in his field as the majority of academic paleontologists object to any organization's commercial selling of fossils. On the other hand, Larson has published scientific papers about dinosaurs and has contributed to community outreach programs, such as teaching inmates about paleontology while serving his two-year prison sentence in Federal prison. The benefits and drawbacks of selling fossils has been
198-562: A lot of Triceratops only had traces indicating scavenging. Yet healed injuries on either a T-Rex or Triceratops would be a clear sign of a fight. A juvenile T-Rex has a bite force of 5,641 newtons compared to the 35,000 newtons of a full-grown adult. Paleontologists use this information to confirmed juveniles do not crush bone but that comes with growth and development, advancing their bite power and strengthening their jaws. Therefore, T-Rex bite force rises in strength and power in correspondence to its size and weight with age. The presence of holes on
231-577: A marketing campaign, including a dedicated website, was launched by the ranchers (with the assistance of commercial paleontologist Pete Larson ) to sell them to a prospective buyer. The ranchers unsuccessfully tried to sell the fossil to several museums, including the Smithsonian and the Museum of the Rockies . With no buyers, the fossils were slated to be sold to a private collector instead. In 2013, Larson presented
264-418: A poster about the tyrannosaur (also referred to as "Bloody Mary", specimen number BHI 6437) at the annual Society of Vertebrate Paleontology meeting, pronouncing it as a potential specimen of the debated tyrannosaur genus " Nanotyrannus ". This presentation was met with significant controversy and ethical complaints, due to the opposition surrounding publishing on privately-owned specimens. Shortly afterwards,

He graduated with a bachelor's degree in 1974. Shortly after graduating college he started Black Hills Minerals. Larson founded what eventually became the Black Hills Institute in 1974. Robert Farrar and Neal Larson, his brother, later joined
330-399: A topic for more than 100 years between academic and professional paleontologists throughout the 20th century. Collaborative work created the primary collections that introduced the public to dinosaurs, but also introduced the idea of fiscal value to resources that some argue fall into the public domain. Academics who reject the practice claim that the high prices that fossils like "Sue" bring in
363-429: A trial on charges unrelated to "Sue", Larson was found guilty and convicted of two felony counts for United States customs violations involving cash brought from overseas, as well as two misdemeanours relating to illegally taking two fossils from federal land. Of the 149 charges faced by Larson and other Black Hills associates, the jury acquitted the defendants of 73 charges, found them guilty of 8 charges and did not reach
SECTION 10
#1732951799897396-582: A verdict on 68 charges. Richard Battey sentenced Larson to two years in Federal prison. Larson appealed to the Eighth Circuit Court against his conviction and was denied. Larson ended up serving 18 months in minimum security prison at the Federal Correctional Complex, Florence , Colorado. In 1997, Larson told the PBS television program Nova that "The government's wrong. The government
429-522: Is not correct in what they've done here." In 1992, Larson's team helped to discover the Tyrannosaurus rex specimen, Stan . In 2013, Larson and colleagues began excavating at a site located in Wyoming , US containing the remnants of three nearly complete skeletons of Triceratops . In 2012, Larson fired his brother, Neal, from the Black Hills Institute amid personal differences. Neal, owning
462-641: The Internal Revenue Service , said the evidence recovered at the Black Hills Institute was more than could have been investigated with "so many bones, so many animals, so many invertebrates that were taken off of public lands, taken internationally, sold internationally." The Justice Department charged Larson with conspiracy, obstruction of justice, illegal collection of fossils, theft of government property, wire fraud, making false statements to government agents and customs violations in November 1993. Following
495-648: The Federal government's raid of Larson's company, the Black Hills Institute, and seizure of "Sue". At the time, Robert Hunt Jr. of the University of Nebraska , secretary-treasurer of the SVP, stated that "America's national heritage of fossils is being bled away by commercial operations, which should be stopped." Mission, South Dakota Mission is a city on the Rosebud Indian Reservation in northern Todd County , South Dakota , United States. The population
528-413: The Seversons had most of the control over mineral rights on Murray land, and whether fossils could be considered minerals (in which case the Seversons would have rights to it) was disputed. Although a previous court had ruled in favor of the Murrays, in November 2018 judges ruled in favor of the Seversons and that fossils could legally be considered minerals in Montana, angering many paleontologists. However,
561-507: The Tyrannosaurus rex named "Sue" from Larson's commercial fossil dealership, the Black Hills Institute of Geological Research. The federal agents seized the fossil of "Sue", along with other fossils and records. The specimen was taken by the Bureau of Indian Affairs. Although Larson had paid the landowner for the find, Williams had reportedly changed his mind, and the U.S. Attorney charged that

660-627: The case was appealed to the Montana Supreme Court in 2020, who ruled that fossils could not be considered minerals, allowing for the Museum of Natural Sciences to acquire the fossils. The specimens were officially revealed to the public in April 2024, in a ribbon-cutting ceremony led by then-state governor Roy Cooper . The specimen is considered one of the best-preserved and most complete fossils of both species of Triceratops and over 98% completeness of

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. He has published scientific and popular works on dinosaur paleontology. Larson has been criticized by some paleontologists for his commercial enterprises and support of private collections. Peter Larson grew up on
891-526: The fossil had been illegally taken from land under Federal administration, because the deeded land fell within the borders of a Native American reservation and the parcel itself was held by the Bureau of Indian Affairs for the benefit of its Native landowner. After the auction of Sue in 1997, which resulted in its sale to the Field Museum , Williams received $ 7.6 million. Keith Nelson, the lead investigator for

957-572: The marketplace prevent public institutions from competing, as private landowners see their fossils as "crops" and are less likely to donate them. Larson has gained some supporters in academia. Robert Bakker , Curator of Paleontology for the Houston Museum of Natural Science, described Larson in 1996 as a responsible paleontologist. The Society of Vertebrate Paleontology (SVP) wrote a formal letter to United States Attorney Kevin Schieffer, endorsing
