Diceratherium

Diceratherium is an extinct genus of rhinoceros endemic to North America, Europe, and Asia during the Oligocene through Miocene living from 33.9—11.6 mya, existing for approximately 22.3 million years.[2] Mass estimates for the type species, D. armatum average around 1 t (2,200 lb)[3]

Diceratherium was named by Marsh (1875). It is not extant. Its type is Diceratherium armatum. It was assigned to Rhinocerotidae by Marsh (1875) and Carroll (1988); to Diceratheriinae by Prothero (1998); to Aceratheriinae by Weidmann and Ginsburg (1999); and to Teleoceratini by Sach and Heizmann (2001).[4][5] Diceratherium had two horns side-by-side on its nose. It lived during the Miocene Epoch.
