Subhyracodon is an extinct genus of hornless rhinoceroses. With a length of 2.4 m (8 ft) and a weight estimated of 381.3 kg (in S. mitis), it was a tapir-sized herbivore on the plains of early Oligocene South Dakota 33 million years ago (White River Fauna). It coexisted with other perissodactyls such as horses, brontotheres, and chalicotheres.[5] Subhyracodon had no horns, relying more on its speed to escape from predators, but a species found at Wind Cave National Park had a pair of bony nasal ridges. The genus Caenopus and species originally referred to as Aceratherium were synonymized into Subhyracodon.[6]
