Physical properties

Hardness: 5 (enameled surface); Color: Dark gray to black (mineralized); Luster: Glossy to dull; Structure: Triangular serrated blade with a distinct root; Specific Gravity: 2.5-3.0

Formation & geological history

Formed through permineralization where minerals like silica or phosphate replace biological tissue; occurs in sedimentary marine deposits primarily from the Miocene to Pliocene epochs (23 to 3.6 million years ago).

Uses & applications

Highly valued for scientific study, museum displays, and private fossil collections. Also used in high-end unique jewelry.

Geological facts

Megalodons were the largest sharks to ever live, reaching lengths of up to 50-60 feet. They shed thousands of teeth throughout their lives, making teeth the most common evidence of their existence.

Field identification & locations

Identified by its large triangular shape, thick root (bourlette), and fine serrations on the edges. Commonly found in coastal sedimentary deposits in Florida, North Carolina, and South Carolina.
