Included in this fantastic fossil tooth set are both, an upper jaw (broader tooth) and a lower jaw tooth of the extinct Mako shark called Isurus hastalis. This prehistoric shark is a member of the White Shark family. Teeth from Isurus hastalis look remarkably similar to the modern Great White Shark less the serrations. Little is known about this species and it is classified in the genus Isurus (Mako) due to its characteristic smooth edges. Some consider this shark the "Grandfather of the Great White".
Both teeth in this set are of top quality and are complete. The enamel has superb preservation with choice natural luster and a chatoyant blue pearly hue.
