Here is a fossil, lower Mako tooth (Isurus) found at Sharktooth Hill near Bakersfield, CA. These teeth have beautiful coloration which is distinct to the location. These teeth are 15.5 million years old!
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.
