Gem-Quality, Agatized Titanothere Tooth SOLD 1.9"

One-of-a-kind! Gem quality, agatized Titanothere tooth cut and polished to reveal the beautiful root structure within!

Above: Titanothere illustration after Burian.

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.

Above: Several species of Titanothere from Henry Fairfield Osborn's The Titanotheres of ancient Wyoming, Dakota, and Nebraska (1927). The illustrations are by Charles Knight.

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 complete, agatized Titanothere tooth (likely upper canine C3). It has been cut in half with each gem-quality side polished to a high sheen to reveal the entire root structure in beautiful detail. 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.

Above: Agatized teeth in these formations are exceedingly rare.

Both halves of this singular tooth will ship in one of our padded jewelry boxes. It will also come with a full-sized Mini Museum certificate, and a set of small acrylic stands.
