Rare Anacheirurus (Lehua) Moroccan Trilobite
Order Phacopida, Family Cheiruridae
Tanssikhte, Zagora, Morocco
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.
