Physical properties

Hardness varies around 5 on the Mohs scale depending on mineralization. Colors range from black, gray, and brown to bluish hues, featuring enamel crowns and a distinctive root structure.

Formation & geological history

Formed through the process of permineralization, where original organic material is replaced by minerals over millions of years in marine sediment deposits.

Uses & applications

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

Geological facts

Fossilized shark teeth are among the most common marine fossils found because a single shark can shed thousands of teeth in its lifetime.

Field identification & locations

Identified by their triangular shape, serrated edges, and distinct root area. Commonly found in riverbeds, coastal cliffs, and ancient marine sedimentary layers.
