Would love some opinions

[SouthTexasFinds]

Found in South Texas. I have my wild guesses but would love some alternate opinions! Thanks for looking

Fossil wood?

I don't recognize this as a fossil. It looks to me like preserved mud-flow. But, I just don't know what it is. What wild guesses are you entertaining?

 

[SouthTexasFinds]

It doesn't look like any of the petrified wood I have seen in this area. I was leaning towards some sort of sea weed or kelp like plant. A preserved mud flow definitely sounds logical looking at one of the sides. I just don't know enough to call either way. I wiped it down a little more, and here's one of the impressions I thought looked almost leaf-like




Here's a shot at one of the ends

My thought was mud flow also.

 

[Harry Pristis]

Leaves would present stems and veins, no? If this is plant matter, perhaps it is a thallus.
Take the object to the closest museum or university, and let us know what you find out.

Maybe just the natural concoidal fracturing of mudstone but I won't swear to it.
