Huntonia
lingulcifer is a Dalmanatid trilobite (Order: Phacopida; Suborder
Phacopina; Superfamily: Dalmanitoidea; Family: Dalmanitidae) from
the Lower Devonian strata of Oklahoma. It is primarily distinguished
from two other species of genus Huntonia from Oklahoma by the markedly
longer pygidial spine. It's occurence is rare and some 10% of the
more common Huntonia. This specimen is not only a typical superb
specimen from the lab of Bob Carroll, but at 88 mm is toward the
size limit of lingulcifer that have been found complete. This example
has been meticulously prepared with modern equipment. | |
