Just kidding about the trilobite requirement for a true field trip, but we must acknowledge a certain charm that comes only from these spiny little beasts. Thanks to my buddy Matthew James, we were directed to an especially fossiliferous set of outcrops of the Carrara Formation in the Nopah Range. The trilobites we collected there are Early Cambrian, roughly 540 million years old. Nick Fedorchuk found the whole specimen photographed above. Everyone collected cephala (“heads”) and the occasional brachiopod and hyolith. It was a very good afternoon for paleontologists!
