Found in NE Colorado today. Not sure what it is.  It is actually a light brown color.

I think the odds are pretty good on that being wood. Like 60/40 maybe 70/30.

Petrified wood?

A view of the small 'ends' would be useful.  It also looks a lot like metamorphic rock.

Do you have a more specific location? You could use a geologic map, https://macrostrat.org/ this one for example and tell us the formation without exposing the exact location. It does not look like the petrified wood that is abundant in the Denver metro, however it can look quite different depending on the formation. I'd lean on odds closer to 40/60

In the area, there is pliocene, oligocene (the White river Formation), and Cretaceous. It does not resemble relatively recent pliocene and oligocene Pet wood and is not right for the cretaceous petrified wood either. So I would say probably not petrified wood. However I have not collected that far north (I'm more southeast Denver) and therefore don't have the best material to compare so I am not 100% sure.

Thank you for your expertise.  I do have another piece of petrified wood and they are very different. I am definitely not an expert. I am trying to figure out the structure of this sample.  The outside layer with the lines and texture, with the inside structure being very different.

The varied texture is likely the result of some minor movement in the sediment. Slumping, dewatering/compaction, that sort of thing. 

I really doubt it is anything significant.
