Trilobite
Crotalocephalina
Moroccan cheirurid
Crotalocephalina (often sold as Crotalocephalus) is the Devonian cheirurid of Morocco with a broad, lobed glabella and a pygidium of four pairs of spines, prepared from the Lochkovian–Emsian limestones near Alnif and Issoumour. It is a mid-priced Moroccan trilobite with a moderate restoration rate; the pygidial spines are the parts to check.
