Fossil shark teeth

Fossilized shark teeth, composed mainly of apatite (calcium phosphate); species cannot be determined from the image

AI-generated identification · may be incorrect

Dark gray to black, glossy, with triangular crowns and some root portions; fossil tooth material is typically about 5 Mohs, though the exact hardness and preservation vary. Individual teeth are small and broken or fragmentary.

AI Estimated Value

About $1–$10 for common small fragments; complete, well-preserved teeth can range from a few dollars to hundreds depending on species, size, and provenance.

Physical properties

Formation & geological history

Shark teeth were shed during life and buried in marine sediment; mineral-rich groundwater replaced or impregnated the original tissues over time. Such fossils span many geological ages, but the image alone does not establish their age.

Uses & applications

Primarily collected and displayed; complete, identifiable specimens may be used in educational collections or jewelry.

Geological facts

Sharks continually replace their teeth, so fossil beds can contain large numbers of shed teeth. Color often reflects minerals in the burial sediment rather than the original tooth color.

Field identification & locations

The pointed crowns and broad, sometimes serrated edges are characteristic of shark teeth, but species identification generally requires clear views of crown shape, serrations, and roots. Fossil shark teeth occur in marine sediments worldwide; these fragments’ locality and age are unknown.
