context_page_description: This list of nautiloids is a comprehensive listing of all genera that have ever been included in the subclass Nautiloidea, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful, or were not formally published, as well as junior synonyms of more established names, and genera that are no longer considered nautiloids.
  Most of the listed genera are found in Part K of the Treatise on Invertebrate Paleontology. Some, added since the year of publication are found simply in various scientific journals and special publications. The named genera are based on type specimens which are housed in various museums and other academic institutions worldwide, available to interested researchers.
  Note that Allonautilus and Nautilus are the only extant genera.
