This is a very interesting trilobite from the Devonian of Oklahoma. The trilobite is a very detailed example of Paciphacops campbelli. This type of trilobite is differentiated from Kainops by the fewer number of lenses in the eyes. The inflated bug is well preserved in a curled position. The fossil has excellent color and contrast and is nicely presented on the sculpted block of matrix. This is a fine specimen of a curled Paciphacops from the Haragan Formation.
