context_page_description: This list of acanthodian genera is an attempt to create a comprehensive listing of all genera that have ever been included in the subclass Acanthodii, 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 acanthodians.
  The list includes 107 genera.
  Extinct genera are marked with a dagger.
  Extant genera are bolded.
