Fossilized mammalian tooth fragment

Likely a fossil molar or premolar; exact taxon cannot be determined from the image

AI-generated identification · may be incorrect

Cream-to-brown, heavily mineralized enamel with repeated triangular cusps and worn ridges; hardness is typically about 5–7 Mohs, with enamel showing a glossy subvitreous luster and dense, fine-grained structure. The exposed broken base appears porous and bone-like.

Physical properties

Formation & geological history

A tooth was buried in sediment and mineralized through replacement and infilling, commonly during the Cenozoic; its precise geological age requires locality and laboratory analysis. The pattern suggests an herbivorous mammal, possibly an ungulate, but identification is uncertain.

Uses & applications

Primarily a natural-history and collecting specimen; scientifically useful for identifying extinct animals, diets, and past environments. It has little industrial or jewelry use.

Geological facts

The repeating enamel cusps are diagnostic anatomical features, not crystal cleavage or rock texture. Fossil teeth can preserve enamel while the internal dentine and root are partly replaced by silica, calcite, or iron minerals.

Field identification & locations

Look for enamel–dentine contrast, biological symmetry, and mineral infill rather than uniform rock texture; common sources include river gravels, caves, and sedimentary exposures. Avoid acid or aggressive cleaning, which can damage enamel.
