Bizarre Crotalocephalus gibbus Moroccan Trilobite

Description: Presented is an excellent example of this unusual and bizarre looking trilobite genus. Take special note of the highly inflated, pronounced glabella, set in extreme opposition to the small eyes.

This is a well-preserved 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.
