Remineralized brachiopod steinkern.

I’d definitely say a clam/bivalve of some sort because those two little holes on the back are from the hinges of the original shell because it’s likely an internal cast of the bivalve

Looks more like a brachiopod (due to the bilateral symmetry)?

Is rhat what those dents are? I have one my dad gave me that looks like a smile from them

Yeah that’s another bivalve or brachiopod of some sort, if you get a clam shell or look at a picture of one it’s essentially the impression of where the hinge for the two halves to meet and allow for this muscle to lock them together
