The "List of ammonite genera" is a comprehensive taxonomic catalog of genera included in the extinct subclass †Ammonoidea (ammonites). The list is maintained as a dynamic Wikipedia article and draws primarily from Jack Sepkoski's 2002 compendium of marine fossil genera, as well as Part L (Ammonoidea) of the Treatise on Invertebrate Paleontology and various peer-reviewed scientific journals.
Scope: The list includes genera commonly accepted as valid, as well as those that may be invalid or doubtful (nomina dubia), those not formally published (nomina nuda), junior synonyms of more established names, and genera no longer considered ammonites. Purely vernacular terms are excluded.
Organization: The genera are listed alphabetically, with entries spanning from Abbasites through Zurcheria. The list covers the full temporal range of ammonites, from the Devonian through the Cretaceous–Paleogene extinction event.
