|  Description:
Example of a pair of members of the Order Asaphida, Family Raphiophoridae,
this one is Raphiophorus parvulus. Much of the genal and rostral
spines are preserved, a feature shared with Ampyx, Cnemidopyge,
and several other trinucleids. Spine preservation is quite rare,
made even more uncommon that we have an associated pair. The Raphiophoridae
were true “survivors’, being the only trinucleoids to
survive into the Silurian. At Upper Silurian age, this taxon was
one of the last of its type.
