Uintatherium Skull Replica


Uintatherium Skull Replica measures 29 x 13 inches or 74cm x 33cm. Uintatherium Skull Replica is Museum quality replica cast in Polyurethane resins. Made in USA. Mammal amblypod of the Eocene Uinta Formation of Colorado. Uintatherium was a large browsing animal. With a length of about 13 feet, a height of 5.6 feet, and a weight up to 2 tons, it was similar to today’s rhinoceros, both in size and in shape, although they are not closely related. The Uintathere’s sternum was made up of horizontal segments. Its skull was flat and concave which is rare and not characteristic of any other known mammal. Its cranial cavity was exceptionally small due the walls of the cranium being exceedingly thick. The weight of the skull was mitigated by numerous sinuses permeating the walls of the cranium, like those in an elephant’s skull.

The large upper canine teeth might have served as formidable defensive weapons, and superficially resembled those of saber-toothed cats. Sexually dimorphic, the teeth were larger in males than in females. However, they also might have used them to pluck the aquatic plants from marshes that seem to have comprised their diet.

The fossils of Uintatherium are among the largest and most impressive of the finds at the excavation of Fort Bridger in Wyoming, and were a focal point of the Bone Wars between Othniel Charles Marsh and Edward Drinker Cope. Between them, Marsh and Cope claimed the discovery of Uintatherium anceps specimens as discoveries of new species on twenty-two separate occasions (and therefore, originally gave these specimens many different names aside from Uintatherium anceps).

Fossils of Uintatherium anceps have been found in the Bridger and Wakashie rock formations, in the states of Wyoming and Utah near the Uinta Mountains, which are commemorated in the generic name. An almost intact skull of Uintatherium insperatus was found in the lower part of the Lushi Formation of the Lushi Basin in Henan Province, China.

A cast of a Uintatherium skeleton is on display at the Utah Field House of Natural History State Park. The skeleton of Uintatherium is also on display at the Smithsonian National Museum of Natural History in Washington, DC.
