Calvert Cliffs Scallop I.D. Help please

[Glenn]

Hi...For some reason this scallop doesn't look like the typical Calvert Cliffs Chesapecten nefrons. Its small, black stained, and appears in MY eye to be taller than normal. I don't have a good nefrons to compare the length to width ratios but it just SEEMS different.  (26.6mm widest x 29.16 tall not at a diagonal). It was found within the same grit as the efrons pieces, the shark vertibrae, the oyster shell etc. that we found. From the southern end of the exposure at the State Park tiny beach. Are C.efrons the only eocene scallops found there? Is it a morphological difference due to its assumed (by me) immaturity and small size? Am I seeing things? Appreciate the help and opinions........Glenn

Could you post the images as .jpeg please? Most aren't going to want to download a file.

Perhaps the same family than Chlamys ?
