A few weeks ago, we took a little drive through the rolling hills of SW Wisconsin. I had to occasionally pull over at some road cuts and stretch my legs. While stretching, why not look for fossils! Here is a pygidium that I can't identify from that trip. It is 5 to 10 times larger than other pygidiums that I normally find in the Eau Claire Formation of the Cambrian Period. Any thoughts?
