Hi Kane, I looked at several maps, then got confused with all of the formations but determined that it is Devonian in this area.   We had a little rain last night and this morning. I went to lay out my "dig" and this fellow caught my eye where I last tilled. All I saw was a smooth arch protruding out of the dirt about the size of a pea. I was surprised after cleaning it up as it looks like a claw. Perfectly symmetrical and slick as a whistle. It has a cavity in the center just like modern critters. I hope the attached pics do it justice. Any idea what it might be ? Thanks again Kane
