Description: Elegant example of a member of the Order Phacopida, Family Cheiruridae with many fine details present. The most diagnostic features of this taxon are the sharp pleural and pygidial spines and the distinctive cephalon. The describer of this one thought it bore a resemblance to the head of a rattlesnake (Crotalus), hence the genus name. The spines may have aided it in staying at the surface of the soft seafloor. It is not to be confused with the common Crotalocepahlus (actually Crotalocephalina). This one has more coplanar cheeks than those found in Crotalocephalina, and much longer pygidial spines. It is closest to the species Crotalocephalus africanus, but that one is found along the coast of Morocco near Rabat. There has been increased interest in trilobites from Jorf leading to discoveries of new types such as this. See my other offerings for a truly stunning Crotalocephalus prepared entirely freestanding.
