context_page_description: This list of prehistoric cartilaginous fish genera is an attempt to create a comprehensive listing of all genera that have ever been included in the class chondrichthyes and are known from the fossil record. This list excludes purely vernacular terms, 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 to be cartilaginous fish. It includes all commonly accepted genera.
  This list currently contains 804 generic names.
  Extinct genera are marked by a dagger.
  Extant taxon genera are bolded.
