Otodus megalodon (whose species name, megalodon, derives from Greek and means "great tooth"), commonly known as Megalodon or Megalodonte, is an extinct [3] 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 demonstrate a cosmopolitan distribution. In the past, O. megalodon was thought to be a member of the Lamnidae family and a close relative of the great white shark (Carcharodon carcharias), but subsequent studies have reclassified it within the extinct family Otodontidae, a group that split from the lineage of the great white shark during the Early Cretaceous.

Size estimates for the Megalodon vary depending on the method used, with maximum total-length projections ranging from 14.2 to 20.3 meters.
