3.5" Hyracodon (Running Rhino) Jaw Section - South Dakota

 
This is a 3.5" long jaw section of Hyracodon nebraskensis. It was collected from the the Brule Formation in South Dakota and would be approximately 32-34 million years old. There are two molars still embedded in the jaw.

Hyracodons were hornless running rhinoceroses with large heads compared to their slight, pony-like bodies. They are an extinct line as I'm sure you've noticed there are no Rhinos browsing the planes of North America today.
