I found this in the Texas Hill Country in a dry creek bed, about 4 miles south of Utopia, Tx. I included a picture of the area in which it was found in case it might lend some clues as to it’s identity. This is the only piece like this that I found. This area is mostly limestone I believe. This sample is not wet- it has a “sheen” to it when rotated. Anyhow, can anyone help? (Sorry if the pics don’t post or come out sideways... I’m still learning all this internet stuff)
