Mammoth or Mastodon Tooth Fragment

Mammuthus / Mammut molar fragment

AI-generated identification · may be incorrect

Composed of dentin, enamel, and cementum, Mohs hardness varies around 5-6 for enamel, color ranges from dark brown to black due to mineralization, dull to vitreous luster on enamel plates.

Physical properties

Composed of dentin, enamel, and cementum, Mohs hardness varies around 5-6 for enamel, color ranges from dark brown to black due to mineralization, dull to vitreous luster on enamel plates.

Formation & geological history

Formed during the Pleistocene epoch (Ice Age), approximately 10,000 to 2.6 million years ago. Organic tooth material is progressively replaced by minerals (permineralization) in sediment over thousands of years.

Uses & applications

Valuable educational specimens, paleontology research, and fossil collecting.

Geological facts

Elephantidae molars are characterized by their distinct parallel enamel ridges (lamellae) designed for grinding tough vegetation during the Pleistocene.

Field identification & locations

Identified by the distinct accordion-like ridges of enamel plates. Frequently found eroding from river gravels, sandbars, and coastal bluffs in North America and Eurasia.
