Teeth of the extinct shark Isurus hastalis have been found in most Miocene and Pliocene marine deposits in California & Florida that produce shark teeth. It is also found in similar age deposits around the world. Long regarded as a member of the mako shark lineage, it is now thought by many paleontologists to be ancestral to the living great white shark.
The extinct Giant Mako, Isurus hastalis, is believed to have been the eventual precursor to the modern Great White shark. This shark was a type of White shark that lived from 30 to 1 million years ago, and grew to large lengths, similar to the maximum size modern Great White shark of today.
- There are 2 main Isurus Shark Teeth that come from Shark Tooth Hill. They are Isurus hastalis, the extinct Giant Mako, and Isurus planus, the Hooked-tooth Mako
