Fossil shark tooth

Likely fossilized shark tooth, possibly Otodus or Carcharhinus; exact identification requires a sharper, closer image

AI-generated identification · may be incorrect

Small, dark gray-to-black crown with a brownish root; enamel is glossy and hard (Mohs ~5–6), while the root is porous and matte. The triangular crown and bilobed root are typical of shark teeth, though details are indistinct.

Physical properties

Formation & geological history

A biological fossil rather than a rock type: the tooth was buried in marine sediment, with mineral replacement or stabilization over millions of years, commonly from the Cenozoic (about 66 million years ago to present).

Uses & applications

Used primarily as a collectible, educational specimen, or jewelry component; it has no meaningful industrial or construction use.

Geological facts

Shark teeth are abundant fossils because sharks continuously shed teeth and their enamel preserves well. Black coloration commonly results from mineralization in oxygen-poor sediment.

Field identification & locations

Common fossil-shark-tooth localities include Florida, North Carolina, Morocco, and Indonesia. Confirm identification by examining serrations, crown shape, root lobes, and possible nutrient grooves under magnification.
