Devonian Fossil

I was a little unsure of this fossil I found at Penn Dixie in western New York. It’s from the Devonian shale. I’d appreciate any help or information.

What are we looking at? 

Can you highlight what you are interested in? 

Most everything is too small to tell anything for sure.

Sorry about that, the other photos didn’t upload properly. The fossil is hard to photograph as it’s on the side of the rock.

OK, thanks for the better picture.

My first thought was crinoid, but, ... I'm not seeing the typical columnals. 
It could be a branching tabulate coral, something like Thamnoptychia limbata ?  :headscratch::shrug::unsure: 

Cool find. :)

Strange indeed. Looking to me like some wierdly long rugose coral.

Some form of elongated coral. Cool find though! Devonian corals are especially interesting.

A burrow of some kind, maybe, or a long solitary coral as you said.

+1 for burrow.

@Fossildude19 I think you're right with tabulate, Tim, but a branchlike one like Cladochonus. Tabulae are absent or sparse in that genus.

 

I've seen similar ones in the Carboniferous (and the genus is Devonian - Permian).

 

Here's one, I think it's the same but viewed from top, not the side.

We do not have much to go on here, effectively just a single photo as the fossil is on the side of the rock and out of focus in the first photo.  Can you take a couple of photos from different angles so we can have an idea of the three-dimensional structure of the fossil?  In particular, what is actual fossil and what is an impression?  I sort of get a sense of a circular tube shaped object (indicated by the circular crystal filled part on the left), with an impression of the tube in the middle (the part in the red circle), and something, maybe impression and maybe actual fossil, on the right.  From the one image though I can't really tell if the basic structure is a straight tube, or if it is curved, irregular, of what.  

 

I also do not see any structures that suggest coral to me.  If it is a coral there should be some indication of septa or tabulae.

Here is my interpretation/guess:

Not in Cladochonus.

Here are a couple other photos, the fossil is at a weird location in the matrix which makes it difficult to get good photos.

Looks like possibly a worn branching crinoid stem.

Still with Cladochonus or similar.

 

Here's another of mine from the Mississippian, so a different species, showing just two corallites of a colony. (mm scale) 

(And a bit of crinoid above it on the left.)IMG_3122.thumb.jpg.d891bf7d1cde4120d481cf14a9fb7507.jpg

 

And yours, with a similarly positioned narrow corallite base where one has snapped off. The narrow stem and bulge of the corallite is typical of the genus.

Thanks for all of the suggestions and information from everyone. It does look like it could be something similar to Cladochonus, i can easily see all of the distinguishing characteristics mentioned above.

I'm in the crinoid camp. It might be crinoid holdfast (anchoring system), that might be the reason why there are no columnals visible, in my opinion. :)

I admit that looks reasonable too. :)

This I think is a good ID.  Well done! :)
