Equus sp. (fossilized molar)

Hardness of 5 on Mohs scale (hydroxyapatite/dentin/enamel mineralized); colors range from dark brown, black, to yellowish-tan; vitreous to dull luster; distinct folded enamel ridges characteristic of herbivore teeth; high specific gravity due to permineralization.

Physical properties

Formation & geological history

Formed through permineralization where groundwater minerals (like silica or calcium carbonates) replace the original organic material of the tooth over thousands to millions of years, typically dating from the Pleistocene epoch or earlier.

Uses & applications

Valuable collector specimen, educational tool in paleontology, and occasionally used in jewelry or display.

Geological facts

Fossilized teeth are among the most common mammalian fossils found because tooth enamel is the hardest substance in the body and resists decay and weathering better than bones.

Field identification & locations

Found frequently in gravel bars, river beds, and eroded banks in areas with Pleistocene deposits. Identified by the complex, corrugated enamel patterns designed for grinding grass.
