Subhyracodon
Extinct Hornless Rhino

Subhyracodon was a cow-sized rhinoceros that lived from the early Chadronian to the Whitneyan (39-30 mya) primarily in the central Great Plains region of North America. During this time period, rhinocerotids occupied the large bodied herbivorous niches in North America. Subhyracodon is recognized by its saddle shaped skull with paired nasal ridges. The Subhyracodon is a hornless rhino. The cheek teeth of rhinocerotids are characterized by a pi shaped surface for grinding up tough vegetation. Field identification of postcranial material of Subhyracodon is often recognized by its size and robustness compared to other taxa within a deposit.
