Gentlemen, It's some fossilized wood that appears to have been modified for a job, maybe pottery related. Can't see it with my hands and eyes at the same time. I've found a lot of petrified wood from east Texas towards the coast. From the west side of the San Jacinto River and beyond most of the lithic source is Edwards and colorado river gravels. It seems east of there including Trinity river and the east side of galveston bay the cherts dissapear and petrified wood (which is quite prevelant in East Texas and West La. piney woods) is more common. Seen it over and over in local collections. G.
