[[Othniel Charles Marsh]] and [[Edward Drinker Cope]] were paleontologists who explored the western United States for fossils in the 1870s-1880s; their personal, vindictive rivalry led to the so-called "[[Bone war]]". In 1872 both explored the area of Fort Bridger, Wyoming and presented at the end of 1872 reports on four different species: ''Dinoceras mirabilis'', ''Dinoceras lacustris'', ''Tinoceras anceps'' and ''Tinoceras grandis''. For its part, Cope made public his discovery of ''Loxolophodon cornutus'', which he later renamed ''Eobasileus cornutus''.

During 1873, a third paleontologist, [[Joseph Leidy]] was able to examine and report on ''Eobasileus'', ''Dinoceras'' and ''Tinoceras''. While he came to the conclusion that ''Eobasileus'' was a genus that was close but distinct from ''Uintaterium'', he also discovered that both Marsh's ''Dinoceras'' and his own ''Uintamastix'' were actually specimens of uintathere. He also suspected that ''Tinoceras'' was the same animal, but he could not determine it with certainty. Later it was finished revealing that most species of dinoceres described by Marsh belonged to the genus ''Uintatherium''<ref>Jacobs, Scott; p 284</ref>.

It was Libby who gave the animals their name, after the Uinta Mountains where the first specimens were found.
==Evolutionary claims==
Mainstream science claims uintatheres existed during the Miocene epoch, some 45-40 million years ago. A claim for ancestry has been made with ''Coryphodon'' (a species of pantodont) based upon superficial similarity between molar teeth. However, the author of the report in question<ref>http://digitallibrary.amnh.org/bitstream/handle/2246/1309//v2/dspace/ingest/pdfSource/bul/B048a18.pdf?sequence=1&isAllowed=y</ref> admitted that the connection was "difficult to understand", even when the report included a drawing of both ''Coryphodon'' and ''Uintatherium'' molars matched with a completely hypothetical animal which served as a bridge between the two species.
As it stands, the evolution of uintatheres cannot be proven beyond the observation of the fossils found in the ground and the needs required of step one of the [[scientific method]]. Creation science holds that uintatheres and all other terrestrial animals were created by an act of God between 6,000-10,000 years ago according to Genesis 1.
