1.4" Curled Paciphacops Trilobite - Black Cat Mountain, Oklahoma

This is a curled, 1.4" long (if outstretched) specimen of Paciphacops campbelli from the Haragan Formation of Oklahoma.

It has amazing surface detail including the many eye facets preserved in each eye. It was prepared under microscope using air abrasives.

There is a second very similar species found in the same layers called Kainops. The most easily identifiable, distinguishing feature is the number of eye facets. Kainops has substantially more eye facets than Paciphacops does. Paciphacops seams to be the scarcer of these two phacopids, but that might depend on the specific layer being collected.

About Trilobites

Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
