Isurus hastalis, Cosmopolitodus hastalis or Carcharodon hastalis, the broad-tooth white shark, is an extinct white shark that lived from the Eocene epoch to the Pleistocene epoch. Its teeth can reach lengths up to 3.5 in (7.5 cm) and are found worldwide, especially in Miocene and Pliocene marine deposits. It is believed to be an ancestor to the great white shark (Carcharodon carcharias), a hypothesis supported by the transitional species Carcharodon hubbelli, and most likely would have been one of the top predators in its ecosystem; preying upon small whales and other mammals. Fossils of marine mammals such as dolphins and desmostylians bearing its tell-tale bite marks indicate this to be true.
