20.8" Fossil Titanothere (Megacerops) Mandible - South Dakota

This is a 20.8" long mandible of the massive titanothere, Megacerops, a Rhinoceros-looking animal that lived during the Late Eocene. It was collected from the Eocene-aged Chadron Formation of South Dakota. It comes from the right side of the lower jaw and still contains three nicely preserved teeth.

There is no gap fill restoration to this jaw, though there are some repaired cracks through the middle and along the edges. Some crack repair can be found through the teeth as well. Other than the section of bone missing along the angle of the jaw, and bone missing from the anterior end, this is an overall complete specimen.

Comes with an acrylic-metal display stand.

Titanotheres were a massive mammal that lived during the Eocene. While they closely resembled modern rhinoceroses, they were actually more closely related to modern horses. They first appeared in the Early Eocene, about 54 million years ago, and went extinct at the end of the Eocene, 34 million years ago. Titanotheres have been described under various genera (Brontotherium, Titanotherium, BrontopsMegacerops was the first and therefore technically correct one.
