This is a Meraspid Trilobite stage of the species Asaphellus fezouataensis from the lower Ordovician of Morocco. This juvenile stage does have only 5 of the 8 body segments of a adult Asaphellus. The missing 3 pleural segments are still “hidden” in the pygidium. These would have developed in later moultings of this juvenile Trilobite. This Trilobite comes with positive and negative side. | |||
