Well-preserved
example of a member of the Order Lichida, Family Odontopleuridae,
with dramatically-displayed genal spines with minute subspines,
a feature not often preserved intact. One of the reasons for the
fine preservation is the fact that this trilobite was prepared by
Bob Carroll, a world-renowned preparator of Oklahoma Devonian trilobites.
Others may use less care, resulting in a less desirable specimen.
Even the tiny nodes of spines on the pleural lobes can be seen.
Overall, a spectacular example of the taxon, rarely offered with
this degree of preparation. Bob only finds a few each year, and
I was able to acquire several examples of his craft this year in
Tucson. The 195 mm by 145 mm by 60 mm shadow box is equipped with
a hanger for display of this fine example of his art, the ONLY example
of Kettneraspis presented this way that I was able to secure.
