    I think it is a broken snail shell. The spiral is the inside of the shell we don’t usually see

    Looks like you have some shell (brachiopod or mollusk-hard to tell) molds (depressions in shape of shell but lacking detail) on the surface of the dark parts of the sample

    That is a trilobite pygidium (the last segment of the exoskeleton). Not unusual to find segments as trilobites were thought to molt as they outgrew their exoskeletons. Nice find!

    Look up images of Conularia. They are related to corals. I found something similar in Devonian limestone in NY.

    This looks like a layered rock composed of material of different strengths. Dolostone interbedded with limestone perhaps.

    Brachiopods. A brachiopod shell shows symmetry (equal left and right parts). A bivalve shell cannot be cut in identical left and right parts. Bivalve symmetry is between shells (the hinge). Usually the “beak” in a bivalve curves to one side.

    Looks like a tooth. The replacement would sit under the concave part. Type? Not sure. Maybe a gator. Just a guess.

    Corals. Looking at cross-sections of them showing radial symmetry.

    Looks like some crinoid pieces in there as well as bryozoans
