In the past several years, many new fascinating invertebrate fossils have been discovered in the rich deposits of southern Morocco, North Africa. Most of those discoveries hail from Ordovician deposits but this fairly recent discovery comes from the Cambrian. This is a maximum size Hamatolenus (Myopsolenus) sp. trilobite exhibiting excellent preservation. It is complete with only the left genal spine, left eye and a portion from the left eye to the edge of the cephalon, restored.
Next to the Paradoxides and Cambropallas sp. trilobites of the North African Cambrian, this Hamatolenus ( Myopsolenus ) trilobite ranks with those other giants as one of the 'much larger than typical' species known in the formation.
