What is "dinocerata"

Dinocerata \Dinocerata\ n. a small order of primitive ungulates of the Paleocene and Eocene.

Syn: order Dinocerata.

Dinocerata ("terrible horned") is an extinct order of plant-eating, rhinoceros-like hoofed creatures famous for their paired horns and tusk-like canine teeth. The earliest dinoceratan, Prodinoceras, appeared in Asia during the Paleocene, but nearly all later types are from North America (dinoceratans must have crossed the Bering land bridge, which may have been exposed during Paleocene-Eocene times). Dinoceratans lived alongside another group of large Eocene plant-eaters, the brontotheres. The most famous dinoceratan is Uintatherium.
