This
trilobite is a member of the Order Phacopida, Family Acastidae
from the Devonian deposits of Timarzit, Morocco known commercially
as the Short-Forked Trident. There are now three named triklobites
possessing a trident. The first was named Walliserops trifurcatus
by Pierre Morzadec. Chatterton and Brett had erected the genus
Parabolops, with the long-forked trident being Parabolops neptunis
and the short-forked Parabolops hammii. The genus name has been
invalidated, and Walliserops has been retained. The third named
trident trilobite, is Walliserops tridens, while the fourth is
Walliserops lindoei. One of the primary differences between this
and the other short-forked variety is that the “tines” of
the trident are more or less parallel in the newest species, while
the outside ones are curved inward in T. hammii. There are currently
no less than THREE unnamed trident trilobites, with this one most
similar to T. lindoei but with a more robust trident much like
the original trifurcatis species. As a result, I will just term
it Walliserops new species affinis lindoei. The Cephalic, occipital,
and pleural spines have all been prepared freestanding as well
as the distinctive “fork”, making for a most esthetic
display with OVER FIFTY freestanding spines. Unlike many trilobites
prepared in Morocco, this one was done using the same painstaking
microabrasive techniques as here in the US, affording a wonderful
piece at a fraction of what a US-prepped example would cost of
comparable quality. (I apologize for the less-than-esthetic photography
while still in the shipping container, but discretion was the better
part of valor with all the spines)..
