          |  Description: 
              Stunning 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 
              cephalic projections. Until recently, this one has been called Cyrtometopus. 
              Two years ago at the Tucson show I was told by one of the foremost 
              collectors of trilobites that he had been told by Richard Fortey that 
              it was actually a type of Crtotalocephalus. I will also leave the 
              name Cyrtometopus here for those confused by the name which is often 
              associated with an altogether different trilobite. The spines may 
              have aided it in staying at the surface of the soft seafloor. This 
              is a stunning example of a new preparation technique being attempted 
              by my main supplier of quality Moroccan trilobites. Relocating to 
              a facility which has a reliable supply of consistent electricity, 
              they have just begun to turn out material NEVER BEFORE offered displayed 
              in such dramatic fashion. A great deal of prep time went into freestanding 
              this specimen with its myriad of spines. Notice even the hypostome 
              can be seen from below.
