 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
cephalic projections. Until recently, this one has been called
Cyrtometopus. Several 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 Crotalocephalus.
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. |
