8.1" Fossil Oreodont (Merycoidodon) Skull - Wyoming
This is a large, 8.1" long skull an Oreodont (Merycoidodon culbertsoni). It was collected from the the Brule Formation in Wyoming and would be approximately 30-34 million years old. There are a few repairs but nothing has been restored.
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.
