Otodus megalodon (whose species name, megalodon, derives from Greek and means "large tooth"), commonly known as megalodon or megalodont, is an extinct species of giant shark that lived from the Early Miocene to the Early Pliocene, about 23–3.6 million years ago (Aquitian–Zanclean), whose large fossil teeth demonstrate that it had a cosmopolitan distribution. In the past it was thought that O. megalodon was a member of the Lamnidae family and a close relative of the great white shark (Carcharodon carcharias), but subsequent studies reclassified it within the extinct Otodontidae family, a family that split from the lineage of the great white shark during the Early Cretaceous.
Size estimates for Megalodon vary depending on the method used, with maximum total length projections ranging from 14.2 to 20.3 meters.
