4.9" Fossil Oreodont (Merycoidodon) Skull - Wyoming
This is a 4.9" long skull of an Oreodont (Merycoidodon gracilis). It was collected from the the Brule Formation in Wyoming and would be approximately 30-34 million years old. Both zygomatic arches and the superior-posterior crest have been restored. The incisors and canines have undergone significant restoration, however the remaining teeth are overall natural and in great 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.
