Merycoidodontoidea

Extinct superfamily of mammals

Merycoidodontoidea, informally known as "oreodonts" or "ruminating hogs," are an extinct superfamily of prehistoric cud-chewing artiodactyls with short faces and fang-like canine teeth. As their name implies, some of the better known forms were generally hog-like in stature, and the group has traditionally been placed within the Suina (pigs, peccaries and their ancestors), though some recent work suggests they may have been more closely related to camels. "Oreodont" means "mountain teeth," referring to the multi-peaked appearance of their molars.
