 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.
This one is displayed in a freestanding “flying” pose.
The pygidial doublure is prepared free of matrix, making for an interesting
display piece. The name has changed several times, from Crotalocephalus
to Crotalocephalina, and recently to Cheirurus, making it hard for
the layman to keep up. Whatever you care to call it, this one will
make a fine addition to any collection. The bicolor preservation
is natural, and adds to the eye appeal of this exquisitely-prepared
piece. |
