has a bit on the local geology; more could be found with further
searching. Glaciation of the area means that there's a slight chance
of almost anything turning up as a bit of rock hauled in by a glacier.
However, much of the area is underlain by Jurassic rocks, and the
specimen looks like Hippopodium, a Jurassic-Cretaceous bivalve of
somewhat uncertain higher affinities (probably modiomorphoidean,
which may relate to the carditids and crassatellids)...Dr. David
There is a photo from "Georgia" called "Mystery
Fossil." I will attach that one and a Giant Atlantic Cockle.
See what you think. If my two had been turned differently, I think
that they would match....Jo
bivalve in Veneroida, Probably Veneridae ...Andrew G.
