Isurus hastalis, or the Broad-tooth mako is an extinct mako shark that lived from the Eocene epoch to the Pleistocene epoch.[1] Isurus hastalis teeth can reach lengths up to 3.5 inches and are found worldwide, especially in Miocene and Pliocene marine deposits.[1] It is believed to be an ancestor to the great white shark, a fact supported by the transitional species Carcharodon hubbelli,[2] and most likely would have been one of the top predators in its ecosystem; preying upon small whales and other mammals.
