Summary

Description

Mammuthus sp. - fossil mammoth tooth from the Pleistocene of America.

This is the occlusal surface (= chewing surface) of a molar from a mammoth - a type of extinct elephant. Mammoths were common in North America during the Pleistocene Ice Age. They are descended from Old World mammoths that crossed into North America via the Bering Land Bridge between far-eastern Siberia and Alaska.

The elongated, worn, slightly irregular ridges of this molar occlusal surface functioned to grind up vegetation.

Classification: Animalia, Chordata, Vertebrata, Mammalia, Proboscidea, Elephantidae
