The Amynodonts are a group of extinct perissodactyls related to true rhinoceroses, they are commonly portrayed as semiaquatic hippo-like rhinos[2][3] 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, Europe and Asia ranging in age from the Middle Eocene to the early Oligocene, with a single genus (Cadurcotherium) surviving into the Early Miocene in Asia.[4]
