Physical properties

Formation & geological history

Shark teeth are commonly preserved in marine sediment, where buried enamel and dentine are mineral-replaced over thousands to millions of years; age may range from Cretaceous to Neogene depending on locality.

Uses & applications

Primarily collected, displayed, and used in educational materials or jewelry; value depends on species, size, completeness, preservation, and provenance.

Geological facts

Shark teeth are abundant fossils because sharks continuously shed teeth throughout life. The visible object appears natural and fossilized rather than a mineral crystal or ordinary rock.

Field identification & locations

Identify by its tooth-like triangular form, hard glossy crown, central cutting edges, and possible serrations; common sources include Florida, Morocco, the southeastern United States, and marine sedimentary deposits worldwide.
