Bivalves from the Mediterenian Sea

[paul monfils]

This is rather difficult because many of the shells are beach eroded, which changes the shape of the ribs, and removes spines that may have been present. And, there is no size reference (a ruler in the pictures), which would also be helpful. That having been said, I am pretty confident that the following species are here: Acanthocardia echinata, Acanthocardia tuberculata, Clinocardium ciliatum. And quite possibly a couple of others.
