Physical properties

Hardness 5 on Mohs scale; color varies from white and tan to black; vitreous or dull luster; amorphous organic-mineral structure.

Formation & geological history

Formed via permineralization where organic teeth are buried in marine sediment and minerals slowly replace the original material over millions of years.

Uses & applications

Valuable for fossil collecting, educational purposes, jewelry, and paleontological research.

Geological facts

Sharks shed thousands of teeth in their lifetime, making their teeth some of the most common fossils found worldwide.

Field identification & locations

Found globally in marine sedimentary deposits, riverbeds, and coastal cliffs; identified by its distinct triangular shape and serrated edges.
