Large, 2.22" Fossil Mako Shark Tooth - South Carolina

This is a large fossil broad-toothed mako (Isurus hastalis) tooth from the Hawthorn Formation. It was collected in South Carolina after it eroded out of the Hawthorn Formation.

Carcharodon (Isurus) hastalis has been historically classified broad-toothed mako shark Eocene epoch to the Pleistocene epoch. Fossil teeth can be found in Miocene and Pliocene deposits worldwide. More recent research has reclassified it as part of the white shark lineage which would make the species name Carcharodon hastalis. You can read more about this here.

Teeth of this shark have been found up to 3 1/2" in length but teeth over 2 1/2" are uncommon and very rare over 3".
