Bargain, 2.6" Fossil Oreodont (Merycoidodon) Jaw - South Dakota

Bargain, Fossil Oreodont (Merycoidodon) Jaw - South Dakota #249294

This is a 2.6" wide, partial lower jaw (mandible) of an Oreodont (Merycoidodon sp.). It was collected from the Brule Formation (White River Badlands Group) in Pennington County, South Dakota and would be approximately 30-35 million years old. The jaw has been exposed from the rock, with a section of rock remaining to hold the bone in place. It's the anterior portion of the jaw, though none of the incisors or canines remained intact.

Comes with an acrylic display stand to assist with presentation.

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.
