Physical properties

Triangular shape, serrated or smooth edges, varying colors (often black, brown, gray, or white depending on sediment), hardness varies based on permineralization.

Formation & geological history

Formed when a shark lost a tooth, which fell to the ocean floor and was buried in sediment. Over time, minerals replaced the organic material.

Uses & applications

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

Geological facts

Sharks constantly shed and replace their teeth throughout their lives, leading to a high abundance of these fossils worldwide.

Field identification & locations

Identified by its distinctive triangular shape, root, and enamel blade. Commonly found in sedimentary marine deposits and beaches.
