Florida Bivalve Identification Help (small - less than 1 cm) 2nd Post

Hello,

 

I found these bivalves in north Cape Coral, FL.  They were in a pile of shells being used for landscaping so I presume that the sediments came from a nearby quarry of ?Pleistocene age, possibly the Caloosahatchee Fm.  Can someone help me verify and identify these fossils?  Thank you!

So,  Florida shells have ancestors and descendants,

The one on the right looks like a cross barred venus shell Chione cancellata

and the one on the left is a spiny jewel box shell Arcinella cornuta Conrad, 1866

 

While their modern common names have stayed the same,  the latin names are different.

It would be difficult for anyone but an expert to differentiate fossil from modern,  but fortunately we have a few such experts on this forum.

Hopefully , one of them with spot your posts.
