Although the matrix hasn't been completly removed from this Oreodont skull, it is still an excellent specimen, with minimal repair. The piece is quite sizable as well, measuring 6-1/2" in length. This would be a showcase piece for any collector, particularly for those interested in mammals from this time period. We've seen quite a few specimens of lessor quality on the market for much higher prices, so this is truly a remarkable piece at an affordable price.
Measures: ~ 9" long x 5-1/4 high x 4-3/8" wide Location: Brule Formation, White River Badlands, South Dakota, USA Time period: Oligocene, ~ 40 m.y.a.
Oreodonts were a family of cud-chewing plant-eater with a short face and tusk-like canine teeth. Some of the better known forms were generally hog-like, and the group was once thought to be related to pigs, peccaries and their ancestors, but recent work indicates they were more closely related to camels. Most Oreodonts were sheep-sized, though some genera grew to the size of cattle. Oreodonts have a unique place in the evolution of ruminant teeth and with peccary-like attributes.They were heavy bodied, with short four-toed hooves. Unlike any modern ruminant, they had long tails.
Oreodants 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. Oreodonts were widespread in North America during the Oligocene and Miocene, but they mysteriously disappeared approximately 4 million years ago.
