Dueling Dinosaurs
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.
