1.3" Mako Shark Tooth Fossil On Sandstone - Bakersfield, CA

Here is a fossil, Mako tooth (Isurus) found at Sharktooth Hill near Bakersfield, CA. These teeth have beautiful coloration which is quite distinct to the location. Quite impressive for a tooth that is 15.5 million years old. This tooth was mounted in sandstone from the same location that it was found.

 


This shark, whose teeth can be found in deposits worldwide, lived from the Eocene to the Pleistocene. It has been historically classified as a broad-toothed mako shark ,(Isurus hastalis). It was then reclassified as Cosmopolitodus hastalis, making it a type of extinct mackerel shark.

More recent research has reclassified it as part of the white shark lineage, which would rename the species to Carcharodon hastalis. You can read more about this here. What classification is correct is still under debate, leading to lots of different labels for these teeth. We prefer the most recent interpretation and label them as Carcharodon hastalis.

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

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



Two highly fossiliferous bone beds in the formation 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 private property surrounding it contains operational pay-to-dig fossil quarries.
