Reminds me of Sigillaria and Lepidodendron trunks (late Paleozoic).

If you inspect the indentations closely (magnifying glass), you may find the reminiscent of teeth marks or vertical lines left from the Brachiopod or Carboniferous coral that had attached themselves to that rock during the Cambrian period....coral type animals. My son and I have found many of these in various locations around Utah, north Arizona, Calif, even in Colorado.........They uniformly clustered together, giving each other enough room to grow (expand).....once it got to crowded, they'd detach and find another location to attache themselves.........it's a good find, but rather common in the locations stated.

Thank you for that info, first I've seen of it.
It was from the middle of Michigan.
Based on the ends I assume it's best as is and cutting would do no good?

Both have been found along the Grand River in central Michigan. I think you could take a slice off the less attractive end and polish to display the cross-section for a specimen. You might want to go back and see if you can find any fossil cones (collectors get excited over them). Here is an article with a drawing of a cone.

Very interesting, thank you.
There is no where to go back to. However frost works pushing rocks up to the surface in fields is about it and pretty random.

rockstock That is a Stigmarian. this is a form genera of a fossil tree root. frequently found in TN, KY, WV, AL

I would window that and run a polish on the cut piece.... Clean it up and keep it!

I don't know if you'd do anything to the outside to avoid losing those details? Thanks! Yes........that's exactly what Fossilman is suggesting.........however, it may not take to a polish easily due to it's matrix and hardness. If it's agate hard and does not crumble or waste away while sanding like some calcified, coral, sea shell, or sand stone embedded material does, it may take to a hand application semi-glossy finish........won't know until you try. As for those abundant small holes on it's surface, I'm still inclined to believe some kind of ancient life (coral, worm, ect.), attached it's self to that submerged root/trunk during some stage after the "trunk/root" life was over and started decomposing..........just a thought.

Yes but WI does not have any Pennsylvanian sediments that I am aware of so it is most likely something else or it was transported.
