And to add to my documentation - recall it was thousands and thousands
of years ago unless
the one was a land form.    Remember I stated the large sand locations
(5-600 feet deep) were
raised 400 feet into the air when the coast was elevated by local
volcano and naturally the
thrust of the Pacific Plate driving North along the North American
plate.  So these shells would
be long dead or converted to stone.

I would expect the warm tropical waters and rich food waters micros
would move in during
the next fertile period.
