My first attempt here. I'm having a great time exploring the Mogollon Rim area near our home here in Arizona. The Kohl's Ranch area near Payson is famous for its Carboniferous brachiopods, but I have a piece that has obvious bryozoans. But in this photo there are two pieces that are "fern" shape. The longer of the two is about 1/2 inch long. They have me stumpred.
