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 smaller number of lenses in the eyes. The inflated bug is complete and well preserved in an enrolled position. The fossil has excellent color and contrast and is nicely presented on the block of matrix that also contains a small horn coral. This is a fine specimen of an enrolled Paciphacops from the Haragan Formation.
