16" Titanothere (Megacerops) Jaw Section - South Dakota

This is a 16" long jaw section of a massive Titanothere, a Rhinoceros-looking animal that lived during the Late Eocene. It was collected from the Eocene aged Chadron Formation of South Dakota. There are five molars present in the jaw.

Restoration is pretty minimal on this jaw. There are a few touchups on the roots of the teeth, and minor crack fill to the jaw. A metal rod has been inserted inside of the jaw and some plaster on the underside the back edge of the jaw to provide stability.

Comes with a display stand.

Titanothere's are an extinct, massive mammal that lived during the Eocene. While the very closely resembled a Rhinoceros, they were more closely related to modern day horses. They first appeared 54 million years ago and went extinct at the end of the Eocene, 34 million years ago. The same genus has been described several times under different names Brontotherium, Titanotherium, Brontops, etc.., though Megacerops was the first and therefore technically correct one.
