"Subhyracodon" is an extinct genus of cow-sized rhinoceroses. It was a medium sized herbivore on the plains of early Oligocene South Dakota 33 milion years ago, smaller than only the "Brontops" and the chalicotheres. "Subhyracodon" had no horns, relying more on its speed to escape, but a species found at Wind Cave National Park had a pair of bony nasal ridges.
