6.25" Titanothere (Megacerops) Upper Jaw Section - Wyoming

This is a 6.25" long maxilla (upper jaw) section of a Titanothere, a Rhinoceros-looking animal that lived during the Late Eocene. It was collected from the Oligocene aged White River Formation of Niobrara County, Wyoming. There are four molars present in the jaw. Upper jaws tend to be much more desirable among collectors than the lower jaws because the molars are much wider and just generally more massive.

There is some minor restoration in the form of crack repair and crack stabilization within one of the molars and along the maxilla bone. Comes with an acrylic 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 todays horses. They first appeared 54 million years ago and when 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.
