Schoharie Creek fossil

[Todd0270]

I collected this in Schoharie Creek near Middleburg, NY. It was half of a very large rock with some exposed fossils. I have been using Muriatic Acid at a 50/50 with water and then power washing the residue off. I still have a ways to go, but found some interesting things. Any ideas on this exposed part?

I see a bivalve on the third picture. Fourth picture looks like Thalassinodes (burrows).

It's pretty hard to tell from the pictures I posted, but the projected area in the 4th photo appears to possibly be a vertebrate. The shape of it fits with some of the Iquanadon vertabrae I've seen on here, does anyone have an idea if this is possible?

It is somewhat similarly shaped, but it does not look like bone. Also not likely to be preserved in marine sediment. I would say, "no", however, I'm no expert on that. Just saying from general knowledge. The bilateral symmetry that a vertebra should have is way off too.

Material from the Schoharie creek in New York is Devonian in age so no Dinosaurs and no Shrimp burrows. You have a Brachiopod in the pic with a ruler, but I am not sure of the genera. Possibly Atrypa as that is very common in the Devonian period.  The rest is missing details to really tell too much. Be careful with that acid bath since the fossils may be preserved with Calcite rather than silicified by Quartz. If they are calcitic then the acid will dissolve the fossils as well.
