Is this Ohio creek find a fossil?

[kitteh]

 I found this in a creek, and would like to know if it is even a fossil.  The creek is in southern Ohio, in the mountains on the glacial boundary.  The river Teays ran through this location.  I usually just have a look if passing creeks and don't know a lot about fossils yet,  though I've found crinoids and brachipods in the same spot, and other fossils.  There are a lot of interesting geofacts.   I couldn't find any pictures online that look like this for anything mississipian.  This one is 145 grams.   (I guess the ruler is all inches, I thought one side was centi as I didn't pay close attention until I added them, sorry.)

Cool rock which may have the remains of burrows on it.

Some sandstones will have harder areas within the whole.

When it is broken up and exposed to weathering the harder areas are more resistant and will stick out.

I think You have a piece of sandstone with some iron concretion and differential weathering.

I'm thinking what Innocentx said - burrows, but it's odd that they're all in a line (or 2 lines?) like that.

Worm tract housing or condo's?
