Help with some fossil shell IDs

[Praefectus]

Hi. I was wondering if anyone could help me identify these shells. Thanks for your help.

 

The first two shells were found in the spoil pile outside of the Aurora Fossil Museum in Aurora, North Carolina. They come from the Lee Creek Mine and are from the Pungo River Formation. 

 

 

 

I don't know much about shells in general, but I think this comes from a scallop. I unfortunately don't have any locality info on it.

Ist shell is a Glycimeris. I don't know the species. The 3rd shell looks like its from the Miocene of Calvert cliffs-Chlamys (Lyropectin) madisonius. But wait for other responses.

Hi,

 

OK with Glycymeris for the 1st one (spelling : 2 "y").
