Ancient marine mammal buried in mud 5 to 7 million years ago, at low tide today. #KingTides #FossilFriday #PurisimaFormation

More marine mammal bones exposed by negative tide. #FossilFriday #KingTides #LowTide

This fossil bone looks like a 3 foot long scimitar.. maybe a rib fossil bone.

Not a scimitar, or rib, but the lower jaw of a whale.
