context_page_description: This list of lobe-finned fish is a comprehensive listing of all genera that have ever been included in the class Sarcopterygii, excluding purely vernacular terms and Tetrapods. 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.
  Extinct genera are marked with a dagger.
  Extant genera are bolded.
