Crotalocephalus (Cyrtometopus) Trilobite (Undescribed)

This is a fairly rare undescribed species of Crotalocephalus which in has often been referred to as Cyrtometopus. What makes it distinct from other species of Crotalocephalus is the pair of projections coming off the front of it's head along with the long pygidial spines.

This maybe the best specimen I've seen of this species in both preservation and preparation. While only 1.7" long, it's a beauty.
