Genuine Trilobite (Ptychopariida) fossil on Matrix with acrylic display stand (6.2 lbs)
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 period. This fossil features three Trilobites that have facial sutures that run along the margin of the glabella and/or fixigena to the shoulder point where the cephalon meets the thorax. These sutures outline the cranidium, or the main, central part of the head that does not include the librigena (free cheeks). *You will receive the exact object in these photos.
