there is a site I have been
studying for six years, that has concreted life forms.
I believe the site was a hydrothermal vent,
that erupted underwater,.
Ther are concreted casts of the plesiosaur,,
mosasaurs, elasmosaurus, and clams? that are uo to 30 inches in diameter.
the one thing that makes this site
different from pompii is that it happened under
water. As the animals decayed
the silt from water action filled in the
cavities. Ther are no bones left but I assume they decayed from the heat of
the ash, but there are plenty of concretions, if you layed aspine and ribs
over them, you would have your animals
