Hash plate. The "snail" is a coral.

This is a fossil with a multitude of crinoid stems and bivalves, some look to be brachiopods. I believe this is coquina, a type of limestone purely made of shells. Nice fossil.

Finally, yes! :)

It's a pretty nice crinoidal limestone block. I don't see evidence of bivalves or brachiopods.

Sorry, I misidentified the sponge and I just took a quick look at the nooks and crannies and assumed they were brachiopods and bivalves as usual, upon closer inspection I see now they are crinoids.

nice find, I often find similar crinoid assemblages here in Ft Payne chert.
