David Kohls is an amateur palaeontologist based in Battlement Mesa, Colorado. He gave thousands of fossils to the Smithsonian and the University of Colorado. An ancient cockroach was recently discovered in his collection, and named after him permission to access places where I thought fossils would be. I established 11 collecting spots and gave them all names, like Claudia's place, after my wife.The main area was basically a lake bottom that had accumulated over time and formed a 1000-foot-thick wall. I'd stand there at the face and pick off naturally weathered, thin pieces of shale, as small as a fingernail or as big as a dinner plate. Sometimes I'd collect 300 to 500 pieces.
