Cosmopolitodus Hastalis
The broad-toothed mako, or Cosmopolitodus Hastalis, was a species of mackerel shark that lived 2.5 to 23 million years ago between the Miocene and Pliocene epochs. The relatively large sharks were apex predators that grew to about 13 feet long.
Scientists have pondered if some species grew larger, based on the size of the 3.5 inch long teeth. The teeth are big and triangular in size. The apex predators had a traditional mako shark form, and they looked similar to the modern great white sharks.
