7" Fossil Oreodont (Merycoidodon) Skull - Wyoming
This is a 7" long skull of Merycoidodon culbertsoni, an Oreodont. It was collected from the the Brule Formation in Wyoming and would be approximately 30-34 million years old. The majority of the bone fragmented within the rock, requiring glue stabilization as well as leaving the rock in place to assist with stability. There is a repaired crack between the anterior and posterior half of the skull. Both zygomatic arches weren't recovered, along with the anterior end of the skull. Partial molars and premolars are present.
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.
