Bargain, 8.3" Fossil Running Rhino (Hyracodon) Skull - South Dakota

Bargain, Fossil Running Rhino (Hyracodon) Skull - South Dakota #249255

This is an 8.3" long, partial skull of the running rhino, Hyracodon nebrascensis. It was collected from the the Brule Formation in South Dakota and would be approximately 30-34 million years old. The specimen includes many of the molars of the upper and lower jaw, along with most of the mandible and portions of the upper skull that have been exposed from the rock.

The specimen has not undergone any restoration.

Hyracodons were hornless running rhinoceroses with large heads compared to their slight, pony-like bodies. They are an extinct line, though: we're sure you've noticed that there are no rhinos browsing the plains of North America today.
