Nicely Prepared 7.3" Oreodont (Merycoidodon) Skull

This is a nicely prepared Oreodont (Merycoidodon culbertsoni) skull from the White River Formation of Pennington County, South Dakota. It's 7.3" long and displays quite nicely.

There is about 5% restoration on the skull. The zygomatic ridges have some restoration, two teeth on the back left side, and a small patch of bone on the bottom edge.

Oreodonts (the common name for Merycoidodontoidea) are extinct mammals most closely related to camels and pigs, though they have no close relatives living today. They were herbivorous animals 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.
