Au Seeker 3,089 Posted December 5, 2018 Share Posted December 5, 2018 Welcome to the forum Lisa to you and your son!! I'm moving your topic to the "Rocks, Minerals, and Fossils" forum so it will be seen by more members to help you get more opinions on what you have found. Quote Link to post Share on other sites
