Fossil Horse Teeth

These Fossil Horse Teeth are from Florida. They are from the Pleistocene Epoch of the Cenozoic Era. They are about 1.5 million years old.

The story of horses is a long and complicated one.  It began some 50 million years ago during the Eocene Epoch with Eohippus. Eohippus was not much like today’s horses. It was a dog sized herbivore that lived in the forests of North America.

In North America the story of the horse ended with the extinction of Equus about 7,600 years ago. In between true horses flourished in North America during the Pleistocene Epoch from about 2.5 million years ago until about 12,000 years ago. Horse teeth fossils are pretty common from this time in many places in North America.
