Hey there @pachy-pleuro-whatnot-odon! Thanks so much for the knowledge! It was found in eastern Travis County, Texas. I do not know a ton about the geology, but would love to learn more. I am adding some photos of my other finds from the same 2 miles of water. If any other specific photo angles would be helpful, just let me know and I can try and capture them. It's an odd color to get my cell phone camera to focus on.
