Hello first time poster. Found as is (not encrusted or buried) along the Whiskey Bridge outcrop in Bryan, TX, along the Brazos river. 4cm in length, about 1.5-1.0cm in diameter. Thought it was petrified wood but a hole at the cross section makes it look like a bone or antler? Surface pattern looks like antler. Has some weight to it and makes a rock like sound when put on a table or something.
