Physical properties

Hardness of 5 on Mohs scale; dark brown to black coloration; vitreous to dull luster; composed of fossilized dentin and enameloid.

Formation & geological history

Formed through the process of permineralization where minerals replace organic material over millions of years, typically dating from the Cretaceous to Neogene periods.

Uses & applications

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

Geological facts

Shark teeth are continuously shed throughout a shark's lifetime, making teeth the most common elasmobranch fossil found worldwide.

Field identification & locations

Easily identified by the distinctive triangular or flattened crown shape with serrated edges; commonly found in riverbeds, coastal cliffs, and marine sedimentary deposits.
