1.3" Fossil Sea Lion (Allodesmus) Tooth - Bakersfield, CA

This is a 2.6" long Allodesmus tooth from Sharktooth Hill near Bakersfield, CA. Allodesmus is an extinct genus of pinniped (Sea Lion) from the Miocene. It is still partially embedded in the sandstone.

It measured about 8 feet long and weighed 800 pounds.
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.
