Found this in the Chesapeake Bay, Miocene period.  To me it looks like a nut with division of hemispheres.  Rock hard. Thoughts?

Welcome to the Forum. :) 

Definitely a internal mold of a bivalve.

Yeah, a cast, and it looks like chert or calcite.

And it is likely in the Cardiidae family, common name "cockle shell".

I also see a bivalve cast.

It looks like hyperostosed fish bone to me. What size is it? Is it possible for you to take a close up to show the texture better?
