fossilnut Posted August 10, 2018 Share Posted August 10, 2018 I'm curious about the imprint in the 2nd picture at the bottom slight left-looks like a very small peanut shell.Any idea what that is. It may also appear in the 3rd picture at the top left. Interested in any thoughts. Thanks Link to comment Share on other sites More sharing options...
