Pelecypod?

Found this pretty little fossil in some Mahantango Formation rocks, and it was by itself and Three D, unusual for the site. Any ideas on the species? Givetian, mid-Devonian, Washington county, MD, Mahantango Formation.

Any ideas? 

A post on the trip I found this from to come...

The pics are blurry and the fossil is laterally compressed so the ID is tough on this one. Based on the size I would initially guess Grammysioidea sp. but there does not appear to be the wavy surface features which mark that genera. Instead it has what appears to be fine concentric growth lines which look similar to Nuculoidea sp. but that genera is much smaller than the specimen appears in the photo. I don't have any good references in front of me but I'll try to look again when I get home.

Thank you, I looked at both online and am also caught between the two. Sorry for the bad pictures, been stormy outside lately. I agree that compression may make a proper ID near impossible. Thank you again!
