Physical properties

Formation & geological history

Formed through the process of permineralization, where minerals in groundwater gradually replace the original organic material of the shark's tooth over millions of years. Dating from the Miocene to Pliocene epochs (approximately 23 to 3.6 million years ago).

Uses & applications

Valued primarily as a collectible specimen, in educational displays, and sometimes crafted into jewelry.

Geological facts

Megalodon was the largest shark to ever live, reaching lengths of up to 50-60 feet. Because shark skeletons are made of cartilage, teeth are the most common and durable fossils found from this extinct apex predator.

Field identification & locations

Found in marine sedimentary deposits worldwide, notably along the southeastern coast of the United States, North Carolina, South Carolina, Florida, and various international coastal or river sites. Identified by its massive size, triangular shape, serrated edges, and a distinct V-shaped bourlette (root area).
