GAL407 Leptauchenia

GAL407 Leptauchenia


This is an exceptional well preserved fossil skull of a Leptauchenia  from the Brule Formation in the White River Badlands of South Dakota. A Leptauchenia was a goat-like species of terrestrial herbivore belonging to the Oreodont family.  This fossil is from the Oligocene period and is about 30 million years old.  The highly detailed upper skull is in matrix that measures 8 3/4″ long x 7 5/8″ wide x 6 5/8″ tall and weighs just over 9 pounds.  The actual skull measures approximately 3 3/8″ wide x 5 1/2″ long. This  Leptauchenia skull is very detailed and rests in a light colored limestone matrix that has been mostly carefully removed to further expose the fossil. This fossil was purchased from a trusted Fossil Hunter, there has been some reconstruction especially on the sides of the teeth but it is 70 % in it’s natural original state. An awesome fossil to display in your 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.
