Exceedingly Rare Anacheirurus (Lehua) Moroccan Trilobite

This plate displays a rarely seen example of a trilobite found in the Ordovician deposits of Tanssikhte near Zagora, Morocco. This taxon has dramatically sweeping genal, pleural, and paired 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. While often called Lehua, it is more correctly referred to as Anacheirurus.
