Possible Crinoid

[Gabby Collins]

Found in the French River. Possible Crinoid?

I think you do have a section of crinoid stem, especially visible in the second and third photos.

I agree, but there are, what looks like lobes of a lung visible as well. I know the probability of them being actual fossilized lungs are extremely low. But what would they be?

Are you referring to this?

 

I don't know but I don't think crinoid and highly doubt they're lungs, especially being associated with crinoid stem. I think perhaps geological and not fossil at all, or some sort of cast made from other marine life like brachiopod/bivalve/coral. More experienced members can probably shed more light.

Sponge, maybe ?

The lower left half of the bit outlined in red looks 'echinodermy' to me. Maybe the base of a cystoid calyx?

I'm not sure the piece above and to the right of it is connected, perhaps a brachiopod valve fragment.

This looks more like a beekite encrusted solitary rugose “horn” coral to me.

Crinoids don't have lungs, or hearts. They use a water-circulatory system for distributing pretty well everything.

Had to look up "beekite" since I hadn't heard of it before, interesting, and that seems reasonable.

I had to look it up too when I first came across someone mentioning beekite. Here is a link to a thread with lots of neat examples of the stuff, and me mentioning the need to look it up myself.
