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.
Age suggested at top of thread was off a few million years..
Another chunk of marine mammal fossil.
Fossil-bones in mudstones. #FossilFriday
