Cape May, NJ ark shell or cockle? - sam wilson - 04-19-2016
Hi all,
I'm new to this forum and this is my first post. I am trying to identify a shell I found on Cape May Harbor. I am familiar with the ark shells but have not found one so clean as this one. It leads me to believe that maybe it is a small Dinocardium robustum. Giant cockle?
I know that this species only just makes it to the Delaware Bay so may be rare here so I would like some expert opinions. Unfortunately, I didn't actually collect the shell and only took a photo of it thinking that it was an ark shell.
Thanks!
Sam

This is not an ark shell, but a cockle, family Cardiidae. Not Dinocardium robustum, possibly Trachycardium muricatum. In any case, it is not a species normally found in your locality, so someone may have purchased it in a bag of shells at a tourist shop, and dropped it where you found it. In which case it could also be a Pacific species.
