Description: This plate displays a rarely seen example of a trilobite found in the Ordovician Fezouata Formation deposits of Beni Zouli , Morocco. This taxon has dramatically sweeping genal, pleural, and pygidial spines. The spines presumably in addition to a deterrent to predators probably served to keep the trilobite near the surface of the substrate, much as snowshoes do. This is a very fine, 3-D example of the type, unusual for Ordovician trilobites, and is rarely offered for sale. The most striking feature of this specimen is the fact that the antennae are preserved, and can be seen in both halves. Note even the segmentation of the antennae can be seen, making this a showcase specimen of the taxon.
