Physical properties

Formation & geological history

Formed through permineralization during the Pleistocene epoch (approx. 2.6 million to 11,700 years ago), where minerals like silica or calcium carbonate replaced the original organic material while buried in sediment.

Uses & applications

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

Geological facts

Proboscidean teeth are uniquely structured with large ridges or plates that wore down continuously to grind tough vegetation like grasses and twigs.

Field identification & locations

Found in gravel pits, riverbeds, and eroding bluffs in North America, Europe, and Asia. Look for the distinct corrugated enamel ridges characteristic of grinding teeth.
