I know it's nothing much, but i found this while gold panning in llano river. Literally 3 shovel scoops in and then this showed up on the shovel! The chances were super slim of that ever happening.
Yes, would like an idea of size. It's definitely a man made bladed stone tool of some kind. I always believed those would have a somewhat multi-purpose use in the ancient Native American times imo. Cutting, scraping, shaving.. Etc.
