 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.
I was told by one of the foremost collectors of trilobites that he
had been advised 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. |
