Here is a quick and (hopefully) easy question for all you Penn Dixie (New York, Erie County) or bivalve experts out there. In going through some of the material I collected last summer, I came across this very nice, but small (1.1 X 1.0 CM) bivalve. It looks most like Lunulicardium eriensis figured on page 160/161 of Wilsons Field Guide to the Fossil of New York. But the book lists it as from the Upper Devonian Canadaway Group and I can't seem to find any reference to it (after a quick search) from the Middle Devonian Moscow Group present at Penn Dixie. My question is: is my ID incorrect or did I just not dig deep enough to find reference to it from Penn Dixie or the Middle Devonian? Thanks for any help. @Fossildude19 @Kane, @Jeffrey P and any others.
