Years of collecting the strand line in Asbury Park, NJ, have revealed a lot of the rarer elements of the modern shallow marine fauna, as well as of the Cretaceous marine biota whose fossils wash up there. But this month I was astounded to come across this shell, which I believe to be a craniid brachiopod's dorsal valve. Based on its condition I can't be sure whether it's modern, subfossil, or even Cretaceous. It's matrix-free and shows signs of having been encrusted by cheilostome bryozoa.

 

Can someone confirm or refute this ID? Can someone with expertise in the Cretaceous coastal plain comment on the likelihood of this specimen's possible Cretaceous origin? Thanks!

Welcome to TFF!

This looks like a limpet shell.  It also looks recent and not fossil.

Lets see what others think about it.

Have a look on Calyptraeidae family, perhaps you will find it (Patella are Patellidae family, Diodora are Fissurellidae family and I don't think they have this little "thing" under them).
