Carcharodon

Carcharodon (meaning "jagged/sharp tooth") is a genus of sharks within the family Lamnidae, colloquially called the "white sharks." The only extant member is the great white shark (Carcharodon carcharias). The extant species was preceded by a number of fossil (extinct) species including C. hubbelli and C. hastalis. The first appearance of the genus may have been as early as the Early Miocene or Late Oligocene.
