Subhyracodon (Latin: "below" (sub), + Greek: "hyrax" (hyrak = 'shrewmouse'), and "tooth" (odontos, referring to the genus Hyracodon)[5]) is an extinct genus of hornless rhinoceroses. With a length of 2.4 m (7 ft 10 in) and a weight estimated of 381.3 kg (841 lb) (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.[6] 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.[7]
