Physical properties

Hardness varies based on replacement minerals (often 5-6), colors range from beige to brown to black, smooth enamel luster, typically triangular with serrated or smooth edges depending on species.

Formation & geological history

Formed through permineralization over millions of years after a shark loses its tooth and it is buried in sediment.

Uses & applications

Valued by fossil collectors, used in paleontology to study ancient marine ecosystems, and occasionally used in jewelry.

Geological facts

Sharks continually shed and replace teeth throughout their lives, leading to a high abundance of fossilized teeth in certain marine deposits.

Field identification & locations

Identify by the distinct tooth shape, root structure, and enamel coating. Commonly found in sedimentary marine deposits worldwide, such as beaches in Florida and the Carolinas.
