Amynodontidae

Amynodontidae ("threatening tooth")[2] is a family of extinct perissodactyls related to true rhinoceroses. They are commonly portrayed as semiaquatic hippo-like rhinos[3][4] but this description only fits members of the Metamynodontini; other groups of amynodonts like the cadurcodontines had more typical ungulate proportions and convergently evolved a tapir-like proboscis. Their fossils have been found in North America, and Eurasia ranging in age from the Middle Eocene to the Early Oligocene, with a single genus (Cadurcotherium) surviving into the Late Oligocene in South Asia (Pakistan).[5] The genus Metamynodon may have survived into the early Miocene.
