What is this fossil

[Raymond Douglas]

I found this years ago - ran across it in a box recently. It is kind of a medium grain sandstone, my collection recollection is that it would have been in Pennsylvanian strata, a thin (maybe 10 inch) sandstone overlying a small coal layer.  I always recalled it as a bit of a mystery. It was before the internet - so we were all a lot slower and dumber then. I always assumed it was some type of a trace fossil - a filled in burrow? BUT - the main thinner segmented tube presents a faint flattened oval or crushed tube when looking at the end. Hard to get a picture of that. Also - it appears to lay on a larger rounded faintly segmented structure. WHAT IS THIS - Thoughts??

Coprolite (?)

It looks like a trace fossil, to me. The segments are irregular. I'm not familiar with that region, but I'm wondering if can't be something in the line of Nereites isp.

I would definately say trace as well.

 

BTW, it would have been funny to have Photoshoped a starship coming over the Tower in your avatar.
