Weird Iron Nodule

[Rjgogo]

So I live near the Mazon creek and have found many fossils in my yard but this one has be puzzled.  Most if not all of the iron nodules I have found have been smooth and oval or rounded in shape,  This one has bumps all over it similar to some species of tree branches.  it is long and round and heavy for it's size and the typical color of most of the iron nodules I have found and opened.  But I have never seen a long one like this.  Hopefully I got the size right on the photos, and I do have much higher resolution photos.  Found lots of grass and ferns and a large piece of coral as well in the past.  Along with lots of coal.  

 

The area where is live was once a very large strip mine area so the spoils were piled all over and if you dig you will find something almost every time.  Edit to add about 6" long and 2" in diameter.

This looks like it could be a Stigmaria - a root from a lycopod tree.

Thanks,  It does look like part of a root,  it is less bumpy on the other side and about the right size.  Pretty cool,.

I agree with Fossildude.

This is an impression (negative) with ab it more detail from PA. Mine's probably a different species. The nubs on yours and the ovals on mine are where the rootlets attached. The lines radiating out at right angles on mine are the rootlets.

It wouldn't be expect to look like a root. The morphology and function are quite different in multiple ways.
