Otodus megalodon (the species name, megalodon, derives from Greek and means "great tooth"), commonly known as megalodon or megalodonte, is an extinct species of giant shark that lived from the Early Miocene to the Early Pliocene, about 23–3.6 million years ago (Aquitanian-Zanclean), whose large fossil teeth indicate it had a cosmopolitan distribution. In the past it was thought that O. megalodon belonged to the Lamnidae family and was a close relative of the great white shark (Carcharodon carcharias), but subsequent studies have reclassified it within the extinct Otodontidae family, a lineage that separated from the great white shark lineage during the Early Cretaceous.

Estimates of the megalodon’s size vary depending on the method used, with maximum total length projections ranging from 14.2 to 20.3 meters.
