Fossil tooth, likely shark tooth

Likely fossilized shark tooth (possibly a small lamniform shark; exact taxon cannot be confirmed from the image)

AI-generated identification · may be incorrect

Triangular, tapered tooth with a dark gray-brown enamel-like surface and lighter mineralized root; hardness roughly 5–7, with glossy enamel and possible serration obscured by wear. Fossil teeth commonly retain dense enamel while the root is porous and replaced by minerals.

Physical properties

Formation & geological history

A biological fossil rather than a rock type: the tooth was buried in marine sediment and mineralized during diagenesis, commonly over millions of years from the Cretaceous through Cenozoic. The surrounding pieces appear to include other small fossils or mineral fragments.

Uses & applications

Primarily used for collecting, education, jewelry, and curios; not generally used industrially or in construction.

Geological facts

Shark teeth are among the most commonly collected vertebrate fossils because sharks continuously shed teeth. Their exact identification requires clear views of both faces, root shape, margins, and serrations.

Field identification & locations

Common in marine sedimentary deposits and beaches, including Florida, North Carolina, Morocco, and Australia. Check for enamel sheen, a distinct root, bilateral symmetry, and genuine mineralization; avoid confusing replicas or ordinary stones.
