Physical properties

Formation & geological history

Formed through the process of permineralization where organic tooth material is replaced by minerals (often silicates or carbonates) over thousands to millions of years during the Pleistocene epoch.

Uses & applications

Valued by fossil collectors, museums, and educational institutions for display and study.

Geological facts

Proboscidean teeth like this are uniquely adapted to their diet; mammoth teeth feature many flat enamel ridges for grazing grass, while mastodon teeth have rounded cusps for browsing leaves and twigs.

Field identification & locations

Found in river gravels, eroding bluffs, and Pleistocene deposits worldwide. Identify by the distinct parallel enamel ridges or cusps on the chewing surface.
