Likely fossilized shark tooth

Possibly *Carcharocles* or *Otodus* sp.; exact identification requires scale and detail

AI-generated identification · may be incorrect

Triangular, brown-gray, mineralized tooth with a darker root area; commonly composed of apatite (tooth enamel/dentine) replaced or preserved during fossilization. Mohs hardness is roughly 5; enamel is typically glossy and harder than the porous root.

Physical properties

Formation & geological history

Formed from a shark tooth preserved in marine sediment, often later mineralized by silica, calcite, or iron oxides. Fossil age may range from Paleocene to Pliocene, depending on genus and locality.

Uses & applications

Primarily a collectible, educational specimen, or jewelry component; it has no significant industrial use.

Geological facts

The broad triangular crown suggests a large predatory shark, but the image does not show serrations or scale clearly enough for reliable species identification.

Field identification & locations

Look for enamel sheen, a distinct porous root, bilateral symmetry, and possible serrations; common sources include Florida, North Carolina, Morocco, and Indonesia. A ruler and close-up of both edges and the root are needed for confident identification.
