Bivalve ID help

Found in the Mount Laurel formation of the C&D canal Delaware. It looks like a modern day razor clam. Does anyone know the genus of this fossil?

Isn´t that a tooth with that serrations??

try something like Nuculana. I see your point Franz. Perhaps this is the toothed margin of the shell showing on the phosphatized steinkern? Here's a link for identifying C&D bivalves:

The part that looks like serrations are the teeth on the bivalve hinge. I think Plax is correct with Nuculana. Here is a modern one showing the teeth. Photo from here-https://naturalhistory.museumwales.ac.uk/britishbivalves/browserecord.php?-recid=284
