Physical properties

Hardness varies around 5 on the Mohs scale due to mineralization. Colors range from black and brown to grey and white depending on the burial sediment.

Formation & geological history

Formed over millions of years through the process of permineralization, where groundwater minerals replace the original organic material of buried teeth.

Uses & applications

Prized by fossil collectors, used in educational displays, and crafted into jewelry.

Geological facts

Sharks shed thousands of teeth during their lifetimes, making fossilized shark teeth relatively common marine fossils.

Field identification & locations

Frequently discovered in riverbeds, coastal cliffs, and ancient marine sediment layers worldwide.
