Crotalocephalus aff. africanus
Trilobites Order Phacopida, Family Cheiruridae
Geological Time: Devonian
Size (25.4 mm = 1 inch): Trilobite is 50 mm long by 25 mm wide (with spines) on a 95 by 110 mm matrix
Fossil Site: Jorf, Morocco
Code: 17164
Price: $325.00
 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
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.
It is not to be confused with the common Crotalocepahlus (actually
Crotalocephalina). This one has more coplanar cheeks
than those found in Crotalocephalina, and much longer pygidial spines.
It is closest to the species Crotalocephalus africanus, but that one
is found along the coast of Morocco near Rabat. There has been increased
interest in trilobites from Jorf leading to discoveries of new types
such as this. See my other offerings for a truly stunning example
