Petrified wood? Other?

[Renfro85]

Hi all,

 

I found what appears to me to be petrified wood, but it wouldn’t surprise me if it was something else. It resembles a wood chip that I nearly ignored it. Any ideas? And thank you in advance:) 

 

(found at the arbor hills nature preserve in Plano, Texas)

 

[Edit: forgive my newby status and allow me to include additional details: this was found very near to a creek at, as mentioned, Arbor Hills Nature Preserve, in Plano, Texas (north Texas...one hour south of the Oklahoma border). Below is a link to more info re: minerals, vegetation, etc., of Arbor Hills, but for quick reference, trees most common in the preserve are cedar oak, cottonwood, red oak. Hope these additions help!

More details

It is a calcite slickenside formed by fault movements. They are very common in the Cretaceous Austin Chalk in the Dallas area. 

 

Look for fluorescent septarian nodules in the area. Outside the park shark teeth occur.
