Can you take a pic with something for scale? I would help to know the size. Also could you take a close-up of those ridges in the first pic. And maybe pics of any other distinguishing features.

I seems like an internal mold of something but I am not sure. I can't place that ridged pattern, but it seems familiar.

The two round/oval shapes kind of give the suggestive shape of crab shells. ( I am not saying that is what it is).

I wonder if it might be a "steinkern" / internal mold / cast of Isognomon maxillata or some similar bivalve.  This is a photo from the Calvert Marine Museum.  Might explain the ribbed pattern...

Glad to be of help, and welcome to the forum.  Come back early and often.  We love to see people's finds :)
