10" Fossil Running Rhino (Hyracodon) Upper Skull - South Dakota

Fossil Running Rhino (Hyracodon) Upper Skull - South Dakota #242023

This is a 10" long, disarticulated 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 jaw, along with various upper skull bone fragments that have been exposed from the rock. The right side of the skull is more complete than the left.

There some repaired cracks here and there where the bone broke away during collection. All of the teeth, while broken in spots, are all natural and haven't been restored.

Comes with an acrylic-metal display stand to assist with presentation.

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.
