Piochaspis sellata Trilobite Chisolm Shale, Pioche, Nevada Cambrian Period ( 541 (+/- 1) - 485.4 (+/- 1.9) million years ago) This fossil measures 1/2" long and is on a matrix measuring 1" by 5/8". Ptychopariida is a large, heterogeneous order of trilobite containing some of the most primitive species known. The earliest species occurred in the second half of the Lower Cambrian, and the last species did not survive the Ordovician–Silurian extinction event. Trilobites have facial sutures that run along the margin of the glabella and/or fixigena to the shoulder point where the cephalon -
