What made this impression?

Thanks to you guys, I think I recognize an endocast/steinkern when I see one. But if I'm right and this is one, I can't for the life of me figure out what would have made this kind of impression. Does this form look familiar to anyone? At first I thought it looked a lot like the rim of a queen helmet shell, but there isn't an opening there to fill with anything that would form a fossil.

 

Found on Myrtle Beach.

 

Thanks!

It is reminiscent of a partial cast of an ammonite chamber. Perhaps Mesozoic sediments from offshore dredging  ?

plications from a large clam maybe

it could be what Rockwood says. I have a found a couple of nice Sphenodiscus in the Myrtle Beach area in the Peedee. Once they are eroded out of or deposited on the beach they would get worn very quickly.
