Uncommon Species of Crotalocephalus (Not Gibbus) - 2.2"

Do not confuse this with the common trilobite Crotalocephalina gibbus frequently seen for sale. This is a different genus that comes from the area near Lghaft, Morocco. The pygidial (tail) spines are distinctly different. This specimen would be about 2.2" long if outsretched but the tail is slightly tucked.
