Physical properties

Hardness of 5 on Mohs scale due to mineral replacement, color ranges from grey to black, vitreous to dull luster, crystalline apatite and phosphate structure.

Formation & geological history

Formed through permineralization where organic tooth material is slowly replaced by minerals in marine sediment over millions of years.

Uses & applications

Collected by enthusiasts, used in jewelry, and studied by paleontologists to understand ancient marine ecosystems.

Geological facts

Shark teeth are shed constantly during a shark's lifetime, making them one of the most common vertebrate fossils found worldwide.

Field identification & locations

Identify by distinctive triangular, serrated or conical shapes in sedimentary rock formations, riverbeds, and coastal cliffs.
