The limestone of the Cedar Glades often have interesting fossils such as this large cephalopod (top) and the curled gastropod. It is hard to believe that middle Tennessee was once under a shallow ocean millions of years ago, but the fossil record is obvious. How else could ancient fossils end up hundreds of miles from the ocean?! When I was a child growing up in this area, I loved hunting for fossils in the limestone along the lakeshores. I once found a large crinoid stem filled with quartz crystals, what an exciting find!
