Titanothere Partial Jaw - 16"

Titanothere Partial Jaw - 16"

One-of-a-kind! Massive Titanothere Jaw measuring 16" and weighing 10 lbs!

The Titanothere first emerged during the Eocene Epoch and spread from Asia to North America. In North America, the Brontothere or "Thunder Horse" is the most plentiful species in the Eocene-Oligocene formations of Nebraska, Wyoming, and South Dakota, though many species are found throughout the continent.

These enormous hooved mammals were roughly 14' in length and stood 8' tall at the shoulder. As evidenced by their physiology, they are closely related to tapirs, horses, and rhinos.

This specimen is a partial jaw of a Titanothere with several teeth still embedded. It measures 16" in length and weighs just over 10 lbs. It is very substantial. The estimated age is 30,000,000 years old.

The specimen was recovered on private land in Nebraska. It was held in a private museum collection for many years. It was acquired at auction in the summer of 2021 after it was deaccessioned from the collection. 

Please Note: This specimen shows numerous signs of repair, all of which should be apparent from the pictures. There is also a small number "87" noted on the back. This ties back to the specimen's days in the museum. While shown in a vertical orientation in some pictures, the jaw does not come with a stand. An individual certificate of authenticity will be included.
