All six families of the Nautilaceae, except for the Aturiidae (Aturia), are derived from the Cenoceras complex in the Middle Jurassic or from Eutrephoceras which immediately followed. The Cenozoic Aturia seems sufficiently derived to warrant familial distinction from its source, the Hercoglossidae.
