Teleoceras

Teleoceras fossiger
Teleoceras major Teleoceras is an extinct genus of rhinoceros that lived in North America during the Miocene epoch, around 4.5 million years ago.

Teleoceras was a grazing rhinoceros, with shorter legs than modern rhinos. It also had a barrel chest, making its build more like that of a hippopotamus than a modern rhino. Like the hippo, it was also semi-aquatic. Teleoceras had a single small nasal horn.

A large collection of Teleoceras major fossils was discovered in Nebraska in 1980.
