6.2" Oreodont (Merycoidodon) Partial Skull - Wyoming
This is a 6.2" long partial skull of Merycoidodon culbertsoni, an Oreodont,from the the Brule Formation, Niobrara County, Wyoming and would be approximately 32-34 million years old. Much of the left side of this skull is still encased in the rock in which it was found. There are several crack repairs and stabilized areas but most of the skull is in tact. The teeth are in good condition.
Oreodonts are an extinct mammal most closely related to camels and pigs. They have no close relatives living today. They were herbivorous, 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.
