I would agree completely that they are both internal molds of bivalves.

(Bit of an old topic, sorry...) 

I'm having a lot of trouble seeing bivalve steinkerns here. What made you guys say that?

I need to correct myself on this one. I meant to say "internal cast," instead of "internal mold," of a bivalve. Basically, that is what they look like. In the lower fossil of the bottommost picture, the pointed cast of the inside off a bivalve's umbo (beak)  is the distinguishing feature.

 

A picture can be seen in pelecypod internal cast-6
