Ft. Worth, Texas - Wood And Wood?

[TXTechdad]

These are from a creek bed in Forth Worth. I believe the first one to be a piece of petrified wood. I like the color and shine.

I thought the second one was wood too but the surface as a very different look with fine lines and the side of it has all kinds of lines without an apparent pattern.

Cheers,

From the photos, I agree with your thoughts. Second piece could be bedded/layerd chert?

I believe the first piece may very well be petrified wood. Could the second be a piece of "slick-n-slide" calcite that formed in a crack in a limestone bed?
