Oreodonts (the common name for Merycoidodontoidea) are extinct mammals most closely related to camels and pigs, though they have no close relatives living today. They were herbivorous animals with short faces and fang-like canine teeth. About the size of a sheep, they roamed the plains of North America in huge numbers during the Oligocene period.
