Description

Carcharodon hastalis
Middle Miocene
Round Mountain Silt, Sharktooth Hill Bonebed
Bakersfield, Kern County, CA, USA

2-3/16 inch tooth.

This shark species was once assigned to the mako genus, Isurus, but recent studies concluded that it is actually the direct ancestor of the great white shark (C. carcharias) and should be placed in the same genus.  Isurus and Carcharodon both belong to the Family Lamnidae.

This tooth is an upper third anterior.
