Crab #2 are these mouth parts?

[Lone Hunter]

This was collected in same place as #1,  half is missing but it didn't get crushed,  hard to tell where concretion stops and crab starts and not sure if it's going to get ID , only two bumps and not sure what to make of them  It looks like parts were pushed up into cavity that don't belong there but what are they? Im assuming mouth parts?  One little piece came off when I was cleaning it.

They look like bivalve shells, to me.

For the  record in the eight years I have hunted this place I never found a bivalve of any sorts.

Pictures 5 and 9 look just like the shape and hinge line of the bivalve Nucula (or something very similar) which are known from the Eagleford.

Like I said never found a bivalve and the rest of it doesn't look like any bivalve.

I don't know invert terminology well enough to name these, but those little toothy protrusions in these pics along the edges of the shell are typical in a lot of bivalves. Here is a picture from the aforementioned genus, Nucula, that exemplifies these features. Not saying this is the exact genus, but I agree with what others have said in that it seems to be bivalve material.

There's a first time for everything.

They definitely look like bivalve shells to me.
