Paciphacops campbelli

Black Cat Mountain Oklahoma Trilobite

Trilobites Order Phacopida, Suborder Phacopina, Superfamily Phacopoidea, Family Phacopidae
Geologic Age: Lower Devonian
Trilobite is 40 mm long
Haragan Formation, Coal County, Clarita, Oklahoma
Remarks: Paciphacops is distinguished from the similar genus, Kainops, by the smaller number of schizochroal eye facets in Pacophacops. Paciphacops also differs from the relativel common genus Phacops in that the glabella protrudes beyond the trilobites anterior margin. If you think it looks a lot like the common Reedops trilobite from Morocco, you would be right; this is because the proximity of what is now Oklahoma and Morocco during the lower Devonian. During the Devonian, Gondwana (where modern Morocco was) and Euramerica (where Oklahoma was) were fairly close, and had adjacent continental shelfs. The Moroccan site and Oklahoma site also were at similar latitudes, such that the respective fauna could be similarly adapted.
