Dueling Dinosaurs

Last updated

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 an adolescent Tyrannosaurus rex and a Triceratops horridus entangled with one another, and entombed in sandstone. The "dueling" inference comes from the numerous injuries sustained by both dinosaurs, including a tooth from the Tyrannosaurus embedded within the Triceratops, although it is not known whether they were actually buried fighting one another. Despite the scientific importance of the specimen, it has remained relatively obscure due to a lengthy legal dispute over property rights to the specimen, which has since been resolved. The fossil is currently in the possession of the North Carolina Museum of Natural Sciences. [1] [2] [3] [4] [5]

History

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. After the fossils and the surrounding rock were excavated, the ranchers unsuccessfully tried to sell the fossil to several museums throughout the decade, including the Smithsonian and the Museum of the Rockies. The ranchers then attempted to sell the specimen to a private buyer, including auctioning at Bonhams, but also to no avail. [6]

In 2016, Lindsay Zanno of the North Carolina Museum of Natural Sciences reached out to Phipps, starting negotiations to purchase the fossil, with funds being raised through the private nonprofit Friends of the North Carolina Museum of Natural Sciences. However, legal issues over rightful ownership of the fossils slowed these negotiations; the Seversons had most of the control over mineral rights on Murray land, and if 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, 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.

Significance

The specimen is considered one of the best-preserved and most complete fossils of both species (as well as the most complete Tyrannosaurus specimen ever found at over 98% completeness), [11] and contains skin impressions, and potentially internal organs, stomach contents, and proteins. [1] [3]

<i>Tyrannosaurus</i> Genus of Late Cretaceous theropod

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, 72.7 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.

<i>Triceratops</i> Genus of ceratopsid dinosaur from the Late Cretaceous

Triceratops is a genus of chasmosaurine ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous period, about 68 to 66 million years ago in what is now western North America. It was one of the last-known non-avian dinosaurs and lived until the Cretaceous–Paleogene extinction event 66 million years ago. The name Triceratops, which means 'three-horned face', is derived from the Greek words trí- meaning 'three', kéras meaning 'horn', and ṓps meaning 'face'.

The Hell Creek Formation is an intensively studied division of mostly Upper Cretaceous and some lower Paleocene rocks in North America, named for exposures studied along Hell Creek, near Jordan, Montana. The formation stretches over portions of Montana, North Dakota, South Dakota, and Wyoming. In Montana, the Hell Creek Formation overlies the Fox Hills Formation. The site of Pompeys Pillar National Monument is a small isolated section of the Hell Creek Formation. In 1966, the Hell Creek Fossil Area was designated as a National Natural Landmark by the National Park Service.

<i>Tyrannosaurus</i> in popular culture

Tyrannosaurus rex is unique among dinosaurs in its place in modern culture; paleontologist Robert Bakker has called it "the most popular dinosaur among people of all ages, all cultures, and all nationalities". Paleontologists Mark Norell and Lowell Dingus have likewise called it "the most famous dinosaur of all times." Paleoartist Gregory S. Paul has called it "the theropod. [...] This is the public's favorite dinosaur [...] Even the formations it is found in have fantastic names like Hell Creek and Lance." Other paleontologists agree with that and note that whenever a museum erects a new skeleton or bring in an animatronic model, visitor numbers go up. "Jurassic Park and King Kong would not have been the same without it." In the public mind, T. rex sets the standard of what a dinosaur should be. Science writer Riley Black similarly states, "In all of prehistory, there is no animal that commands our attention quite like Tyrannosaurus rex, the king of the tyrant lizards. Since the time this dinosaur was officially named in 1905, the enormous carnivore has stood as the ultimate dinosaur."
