Fossil Lycophytes from Texas

[Planko]

Hey Everyone, 

 

I need some help. Still not sure but think this might be a fossil piece of Lycophytes or similar species. Found North Sulfur River in Delta County, Tx about two weeks ago. I cannot find anything online that shows that this species or similar was in Tx. My web hunting skills are not the best in the world though. 

 

Any responses are greatly appreciated.

Sorry, but I think it represents a geologic structure rather than a fossil. The contrast in appearance between the two sides may suggest a nonconformity. That is a time when the sedimentary record was interrupted by some change in the environment.

I dont know what it is--I am curious about the lycophyte guess and its basis...As Rockwood suggests it could be geologic but the one side does also seem to have an odd badly preserved palm/cycadioid trunk fragment look to it. Has any other plant material been found in the area?  There appears to be some interesting very fine laminations/layering in the one area that I highlited with the red arrow that may or may not hold a clue. Hoping some of the Texas folks will chime in with some local knowledge. Interesting find!

Regards, Chris

Guess, and just that, was from my YouTube posting of this piece. There is a better look at it there along with description. Smooth on one side with a curve and, well, you see the other side.

 

I am not sure about any other plant material other than smaller pieces of petrified wood. That is why I am posting here.
