==Description==
Characteristics shared by all brontotheriid species include an abbreviated face, an elongated postorbital cranium, and the outer shearing blades on the molars bearing a "W" or wedge shape<ref>http://digitallibrary.amnh.org/dspace/handle/2246/5913</ref>. Despite being members of Perissodactyla, all species had four toes on the front feet; the rear feet bore three.

The familiar species (''Embolotherium'', ''Megacerops'', etc.) were of large size, easily standing over eight feet at the shoulder with estimated weight of nearly four tons. The head bore horns on the snout made entirely of bone; unlike rhinos, these horns were side-by-side instead of one behind the other, and in some brontothere species the horns were fused into a bizarre "slingshot" or "battering ram" appearance. It has been surmised that the horns were used in combat between bulls during mating season.
