Hi!

Florida is an ancient immerged platform. Florida
underground is very rich in marine fossil molluscs of
the latter Tertiary. They can be very well-preserved
(even some cowries of the siphocypraea subgenus have
kept their glossy aspect and original colours),
especially cones.
My opinion is that those cones are FOSSILS and that's
certainly why they're very hard to identify!
Do you agree?
Perhaps it's untrue but it's the idea that came first
to my mind.
Sincerely,

Fabien Goutal
