Physical properties

Hardness of 5 on the Mohs scale for fossilized enamel, white to grey color, vitreous to dull luster, composed primarily of calcium phosphate (apatite).

Formation & geological history

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

Uses & applications

Used in educational displays, jewelry, fossil collecting, and paleontological research.

Geological facts

Shark teeth are shed continuously throughout a shark's life, leading to abundant fossilization. Ancient megalodon teeth are among the most prized by collectors.

Field identification & locations

Found globally in marine sedimentary deposits, riverbeds, and coastal cliffs. Identify by triangular, enamel-coated morphology and distinctive root structure.
