Extinct Giant Mako Shark Cosmopolitodus is an extinct genus of mackerel shark that lived between thirty and one million years ago during the late Oligocene to the Early Pleistocene epochs. Its type species is Cosmopolitodus hastalis, the broad-tooth mako (other common names include the extinct giant mako and broad-tooth white shark). In 2021, Isurus planus was reassigned to the genus, and thus became the second species C. planus. However, some researchers still consider both species of Cosmopolitodus as species of Carcharodon. C. hastalis teeth can grow up to 3.5” in length, suggesting a very large shark. Its body was probably very similar to that of modern great whites. It is also believed to have a cosmopolitan distribution, with C. hastalis teeth being found worldwide. The species is divided into two forms based on tooth morphology, each with a unique evolutionary line. The maximum adult length is estimated between 16 and 23 ft. Smaller individuals were about 8.5–14.8 ft long. C. hastalis was a confirmed hunter of marine mammals. It most likely would have been one of the major predators in its ecosystem, preying upon small whales and other mammals. Trace fossils in the form of tooth marks on the bones of a Pliocene dolphin of the species Astadelphis gastaldii reveal that C. hastalis attacked its prey from below and behind, much like the modern great white shark does.
