Physical properties

Formation & geological history

Formed through the process of permineralization, where minerals gradually replace the original organic material of a shark's tooth over millions of years (commonly Cenozoic or Mesozoic eras).

Uses & applications

Used in fossil collecting, education, jewelry, and decorative display pieces.

Geological facts

Shark teeth are shed continuously throughout a shark's lifetime, with individuals losing thousands of teeth, making teeth the most common shark fossil found.

Field identification & locations

Identified by its characteristic triangular shape, smooth or serrated cutting edges, and distinct root structure. Frequently found in riverbeds, coastal erosion areas, and quarries.
