Is This A Track Fossil?

[tomdonohue1]

Hi, I was wondering if someone could help me identify this.

Found near Corry, PA (NW PA) in a stream bed. Bedrock in the area is U. Devonian & Mississippian, rock type is SS or conglomerate. I realize land animals were not present in the Devonian, so I'm thinking its Mississippian. Is this a track fossil or something else? If it is a track, does anyone know what could have made it? It seems like something relatively heavy may have depressed the sediment (I tried to show the depth with a dime), and it wouldn't just be a twig or leaf.

Doesn't look right for a trackway, to me.

I'm thinking more along the lines of a 3 dimensional branching type of coral, bryozoan, or infilled burrow, that may have eroded away partialy, leaving little detail, and the "impression" of great weight having made this.

I'd like to hear other thoughts and opinions, however.

I would agree on the branched bryozoan but it also could be infilled converging worm burrows.
