7.3" Partial, Fossil Oreodont (Merycoidodon) Skull - Wyoming
This is a 7.3" 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. Both zygomatic arches are present, though each required crack repair and the left arch required some gap fill restoration. Many of the teeth are still present with some crack repair through fractures. The skull section posterior to the orbitals has been repaired where it broke away from the anterior half. The mandible was not recovered with this skull.
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.
