hamatus elegantus Oklahoma Trilobite
"Oklahoma Trilobites Prepared By Bob Carroll"
Lichida, Family Odontopleuridae
Time: Lower Devonian
mm = 1 inch): Trilobite is 60 mm long by 50 mm wide (including spines)
on a 95 mm by 160 mm matrix
Site: Haragan Formation, Coal County, Clarita, Oklahoma
A well-preserved example of a member of the Order Lichida,
Odontopleuridae, Dicranurus hamatus elegantus is an Odontopleurid
trilobite from the Lower Devonian deposits of Coal County,
Oklahoma This Lichid is treasured by collectors as one of the
most exotic spiny trilobites and is morphologically similar
to its larger cousin Dicranurus
monstrosus from the Atlas Mountains
of Morocco (see my Moroccan trilobites for an example of a
remarkable freestanding specimen). This specimen is the typical
superb quality that comes from the prep lab of Bob Carroll.
Notice the dramatic retorted occipital “horns” as
well as the detail in the genal spines. Even the matrix has
been elegantly sculpted to add to the overall appearance. 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. 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 this
elegant example of his craft this year in Tucson. This is Bob”s
signature species, and is seen on his T-shirts, hats, and business
cards. Bob is proud of these works of art and justifiably so.
