Physical properties

Formation & geological history

Formed through permineralization where hydroxyapatite in the tooth was replaced by minerals (primarily phosphate) from seafloor sediments during the Miocene to Pliocene epochs (approx. 23 to 3.6 million years ago).

Uses & applications

Highly valued by fossil collectors, used in high-end jewelry, and utilized for paleontological research into ancient marine ecosystems.

Geological facts

The Megalodon was the largest shark to ever live, reaching lengths of up to 50-60 feet. Their teeth are the most common fossil remains found because sharks shed thousands of teeth throughout their lives.

Field identification & locations

Identify by its large size (usually over 2 inches), triangular shape, and the presence of a 'bourlette' (the dark band between the root and enamel). Commonly found in coastal areas of the SE United States (e.g., Florida, South Carolina).
