FORTEY, R. A. 1974. A new pelagic trilobite from the Ordovician of Spitsbergen, Ireland, and Utah. Palaeontology17, 1, 111–124.

R. A. Fortey Opipeuter inconnivus gen. et sp. nov. is described. It is included with Cremastoglottus Whittard in a new family, the Opipeuteridae, which is probably closest to the Remopleurididae. It is also possible that Opipeuter is related to the enigmatic trilobite Bohemilla Barrande. The functional morphology of Opipeuter indicates a pelagic mode of life.
