1.45 Inch Mako Shark Tooth Fossil (Sharktooth Hill)

Here is a very nicely preserved Mako tooth (Isurus hastalis) found at Sharktooth Hill near Bakersfield, CA. It's 1.45 inches in length and displays beautiful coloration. Quite impressive for a tooth thats 15 million years old.

 


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".

Sharktooth hill is located in the foothills of the Sierra Nevada Mountains near Bakersfield, California. It represents and exposure of the Temblor Formation, a middle Miocene marine deposit. 15 million years ago the sea levels were substantially higher and Central California was cover by what is known as the Temblor Sea.



There are two highly fossiliferous, bone beds in the formation that were created when fossils originally deposited at the bottom of the sea eroded out of the rocks, were concentrated by ocean currents and subsequently reburied. Because the fossils in these bone beds are reworked, only isolated teeth and bones are found in these beds.

Today the original Sharktooth hill is a National Natural Landmark but there is private property surrounding it on which there are operating fossil quarries.
