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 four named trilobites 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 varieties 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 trifurcatus 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 micro abrasive
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). |
