This is an Oreodonta skeleton from the Brule Formation in the White River Badlands of South Dakota.  This was a goat-like species of terrestrial herbivore belonging to the Oreodont family.  This museum quality specimen has been professionally prepped to show it’s nearly complete skull, vertebrae, many of it’s ribs, as well as it’s pelvis, leg and other bones. While in reality, this skeleton is only about 50% complete the bones you do see have had very minimal fill and repair. It measures 25″ long. It is 16″ wide at it’s widest point and angles down to 7″ on the other end. The skull itself measures 10″ long and has been prepped on both sides to show it’s nearly full set of teeth on both sides. It sits in it’s original matrix but has been mounted on top of molders clay to display beautifully at an angle from 3″ high at it’s skull to nearly 11″ high at it’s pelvis. It weighs in at around 110 pounds. A  fossil of this caliber does not come around that often! An excellent addition to any fossil collection!

The Oreodonta is an extinct suborder of mammal in Order Artiodactyla, and therefore distantly related to pigs, hogs, camels, hippopotamuses, and the pig-like peccaries.  Over 50 species of Oreodonta have been described. They first appeared some 50 million years ago during the warm Eocene and were widely prevalent during the Oligocene in the grasslands, prairies or savannas of what is now the North American badlands.  Today, fossil jaws and teeth of the Oreodonta are commonly found in the White River badlands in South Dakota, Nebraska, and Wyoming.  Oreodonts are Artiodactyls, even toed ungulates, sometimes called a cross between a pig and a sheep. Note that they have both large canine front teeth, but also molars for chewing plants.  They were herding animals and grazers, eating mostly grasses.  They averaged three to four feet long.
