Fossil shark tooth

Fossilized shark tooth; species indeterminate from the image

AI-generated identification · may be incorrect

Small, cream-colored tooth with a pointed crown and broad root; fossil teeth are chiefly mineralized calcium phosphate (apatite), Mohs hardness about 5. The image is not detailed enough to assess serrations or identify the species.

Physical properties

Small, cream-colored tooth with a pointed crown and broad root; fossil teeth are chiefly mineralized calcium phosphate (apatite), Mohs hardness about 5. The image is not detailed enough to assess serrations or identify the species.

Formation & geological history

Shark teeth were shed and buried in marine sediment, then fossilized through mineral replacement or infilling. The tooth’s geological age and formation cannot be determined from the photograph.

Uses & applications

Collected as a fossil and used for education or display; shark teeth are not generally used in industry or jewelry.

Geological facts

Sharks continually replace their teeth, so fossil teeth are relatively common in sedimentary deposits.

Field identification & locations

Look for a distinct crown-root shape and fossil-mineral texture; species identification often requires clear views of the root and any serrations. Found in marine sedimentary deposits worldwide.
