This list of ammonites is a comprehensive listing of genera that are included in the subclass †Ammonoidea, excluding purely vernacular terms. The list includes genera that are accepted as valid, as well those that may be invalid or doubtful, or were not formally published, as well as junior synonyms of more established names, genera that are no longer considered ammonites. Most of the generic names in this list come from Jack Sepkoski's 2002 compendium of marine fossil genera, which can be corroborated by other sources such as Part L, Ammonoidea, in the Treatise on Invertebrate Paleontology. Additional generic names included come from the Treatise or various peer review scientific journals.

This is a list of frigates of World War II. The list includes frigate class ships, such as US Navy "destroyer escorts", British "escort destroyers" and sloops. Note that US Navy "escort destroyers", are destroyer class vessels and found in that list; the List of ships of World War II contains major military vessels of the war, arranged alphabetically and by type. The list includes armed vessels that served during the war and in the immediate aftermath, inclusive of localized ongoing combat operations, garrison surrenders, post-surrender occupation, colony re-occupation and prisoner repatriation, to the end of 1945. For smaller vessels, see List of World War II ships of less than 1000 tons; some uncompleted. Ships are designated to the country under which they operated for the longest period of the World War II, regardless of where they were built or previous service history.
