The following basically follows Teichert (1988) with the Palcephalopoda/Neocephalopoda hypothesis incorporated; except that Teichert's two Subclasses '''Endoceratoidea''' and '''Actinoceratoidea''' have been discarded, since the two orders [[Endocerida]] and [[Actinocerida]] are probably not so distinct from their contemporaries as to justify such a high taxonomic ranking.
