Line 1: {{short description\|None}} ~~This '''list of xiphosurans''' is a listing of all [[Genus\|genera]] in the class [[Xiphosura]], excluding purely vernacular terms. The list includes '''39''' genera.~~ This '''list of xiphosurans''' is a comprehensive listing of all [[genera]] that have ever been included in the order [[Xiphosura]], excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (''[[nomen dubium]]''), or were not formally published (''[[nomen nudum]]''), as well as [[Synonym (zoology)\|junior synonyms]] of more established names, genera that are no longer considered xiphosurans and misspellings. The list currently includes '''54''' names out of which '''31''' are considered valid xiphosuran genera. As of 2019, there were around '''80''' extinct species of xiphosurans<ref>{{cite book\|chapter-url=http://www.wsc.nmbe.ch/resources/fossils/Fossils19.5.pdf\|title=World Spider Catalog\|last1=Dunlop\|first1=J. A.\|last2=Penney\|first2=D.\|last3=Jekel\|first3=D.\|publisher=[[Natural History Museum Bern]]\|year=2019\|chapter=A summary list of fossil spiders and their relatives\|pages=1–296}}</ref> and '''4''' extant species of xiphosurans recognized as valid. [[Extinction\|Extinct]] genera are marked with a dagger ([[†]]). [[Extant taxon\|Extant]] genera are '''bolded'''. == Naming conventions and terminology == ~~[[File:Limule(dD).jpg\|thumb\|''[[Limulus polyphemus]]'']]~~ There is no "official" or "canonical" list of xiphosuran genera. The closest thing is found contained in the regularly updated ''Summary list of fossil spiders and their relatives'' in the [[World Spider Catalog]], which include just the extinct species. The vast majority or all of the content of the list below, including the valid genera, preoccupied names, junior synonyms, misspellings, taxonomical classifications and sites of discovery, is based upon the 2019 edition of the summary list. ~~[[File:Naturkundemuseum Berlin - Mesolimulus walchi - Solnhofen.jpg\|thumb\|''[[Mesolimulus walchi]]'']]~~ ~~[[File:Tachypleus tridentatus.jpg\|thumb\|''[[Tachypleus tridentatus]]'']]~~ Naming conventions and terminology follow the [[International Code of Zoological Nomenclature]]. Technical terms used include: ~~{\| class="wikitable sortable"~~ * '''[[Synonym (zoology)\|Junior synonym]]''': A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the [[Type (zoology)\|type specimens]] are later assigned to the same genus, the first to be published (in chronological order) is the senior synonym, and all other instances are junior synonyms. Senior synonyms are generally used, except by special decision of the ICZN, but junior synonyms cannot be used again, even if deprecated. Junior synonymy is often subjective, unless the genera described were both based on the same type specimen. \|- * '''''[[Nomen nudum]]''''' (Latin for "naked name"): A name that has appeared in print but has not yet been formally published by the standards of the ICZN. ''Nomina nuda'' (the plural form) are invalid, and are therefore not italicized as a proper generic name would be. If the name is later formally published, that name is no longer a ''nomen nudum'' and will be italicized on this list. Often, the formally published name will differ from any ''nomina nuda'' that describe the same specimen. ~~! Genus~~ * '''''[[Nomen oblitum]]''''' (Latin for "forgotten name"): A name that has not been used in the scientific community for more than fifty years after its original proposal. ~~! Authors~~ * '''Preoccupied name''': A name that is formally published, but which has already been used for another taxon. This second use is invalid (as are all subsequent uses) and the name must be replaced. As preoccupied names are not valid generic names, they will also go unitalicized on this list. ~~! Year~~ * '''''[[Nomen dubium]]''''' (Latin for "dubious name"): A name describing a fossil with no unique diagnostic features. ==Xiphosuran genera== {{legend\|#FFFFFF\|Valid genera}} {{legend\|#E6E6E6\|Non-valid genera}} † = Extinct {\| border="0" style="width: 100%;" ! width="90%" \| ! width="5%" \| ! width="5%" \| \|- \| valign="top" style="border:0px" \| \| †''[[Anacontium]]''<ref name="phylogenyarchive">{{cite web \| last = Haraamo \| first = Mikko \| title = Mikko's Phylogeny Archive entry on "Xiphosura" \| date = 2003-02-21 \| url = http://www.helsinki.fi/~mhaaramo/metazoa/protostoma/arthropoda/xiphosura/Xiphosura.htm \| accessdate = 2008-09-11 }}</ref> \|\| Raymond \|\| [[1944 in paleontology\|1944]] {\| class="wikitable" \|+ !'''Genus''' !'''Author(s)''' !'''Year''' !'''Status''' !'''Age''' !'''Location''' !Notes \|- \| †''[[Alanops]]'' \| †''[[Archeolimulus]]''<ref name="sepkoski">{{cite journal \| last = Sepkoski \| first = Jack \| title = A compendium of fossil marine animal genera \| journal = Bulletins of American Paleontology \| volume = 364 \| pages = 560 \| year = 2002 \| url = http://strata.ummp.lsa.umich.edu/jack/showgenera.php?taxon=279&rank=phylum \| accessdate = 2007-12-20 }}</ref> \|\| Chlupác \|\| [[1963 in paleontology\|1963]] \|Racheboeuf \|[[2002 in paleontology\|2002]] \|Valid \|[[Carboniferous]] \| * {{flag\|France}} \| \|- \| †''[[Anacontium]]'' ~~\| †''[[Austrolimulus]]''<ref name="sepkoski"/> \|\| Riek \|\| [[1955 in paleontology\|1955]]~~ \|Raymond \|[[1944 in paleontology\|1944]] \|Valid \|[[Permian]] \| * {{flag\|United States}} \| \|- \|†''[[Archeolimulus]]'' ~~\| †''[[Bellinuroopsis]]''<ref name="sepkoski"/> \|\| Chernyshev \|\| [[1933 in paleontology\|1933]]~~ \|Chlupáč \|[[1963 in paleontology\|1963]] \|Valid \|[[Middle Ordovician]] \| * {{CZE}} \| \|- \| †''[[Austrolimulus]]'' ~~\| †''[[Bellinurus]]''<ref name="sepkoski"/> \|\| Meek & Worthen \|\| [[1865 in paleontology\|1865]]~~ \|Riek \|[[1955 in paleontology\|1955]] \|Valid \|[[Triassic]] \| * {{flag\|Australia}} \| \|- \|style="background:#E6E6E6;" \| ~~\| †''[[Bembicosoma]]''<ref name="sepkoski"/> \|\| Laurie \|\| [[1899 in paleontology\|1899]]~~ †''[[Belinuropsis]]'' \|style="background:#E6E6E6;" \| Matthew \|style="background:#E6E6E6;" \| [[1910 in paleontology\|1910]] \|style="background:#E6E6E6;" \| ''[[Nomen dubium]]'' \|style="background:#E6E6E6;" \| [[Carboniferous]] \|style="background:#E6E6E6;" \| * {{flag\|Canada}} \|style="background:#E6E6E6;" \| Too poorly preserved to be assigned to any particular [[arthropod]] group. \|- \| †''[[Belinurus]]'' ~~\| †''[[Bunaia]]''<ref name="sepkoski"/> \|\| Clarke \|\| [[1920 in paleontology\|1920]]~~ \|Bronn \|[[1839 in paleontology\|1839]] \|Valid<ref name="beli">{{cite journal\|url=https://www.cambridge.org/core/services/aop-cambridge-core/content/view/99BE92900866081467547C811FC3DDEB/S0022336021000536a.pdf/belinurus_bronn_1839_chelicerata_xiphosura_has_priority_over_bellinurus_pictet_1846.pdf\|title=''Belinurus'' Bronn, 1839 (Chelicerata, Xiphosura) has priority over ''Bellinurus'' Pictet, 1846\|first1=James C.\|last1=Lamsdell\|first2=Matthew E.\|last2=Clapham\|journal=[[Journal of Paleontology]]\|pages=1352–1355\|year=2021\|volume=95\|issue=6\|doi=10.1017/jpa.2021.53\|doi-access=free}}</ref> \|[[Carboniferous]] \| * {{flag\|Canada}} * {{flag\|England}} * {{flag\|United States}} * {{flag\|Ukraine}} * {{flag\|Wales}} \| \|- \| †''[[Bellinuroopsis]]'' ~~\| †''[[Bunodella]]''<ref name="sepkoski"/> \|\| Matthew \|\| [[1889 in paleontology\|1889]]~~ \|Chernyshev \|[[1933 in paleontology\|1933]] \|Valid \|[[Devonian]] \| * {{flag\|Russia}} \| \|- \|style="background:#E6E6E6;" \| ~~\| †''[[Bunodes]]''<ref name="sepkoski"/> \|\| Eichwald \|\| [[1854 in paleontology\|1854]]~~ †''[[Bellinurus]]'' \|style="background:#E6E6E6;" \| Pictet \|style="background:#E6E6E6;" \| [[1846 in paleontology\|1846]] \|style="background:#E6E6E6;" \| Synonym \|style="background:#E6E6E6;" \| N/A \|style="background:#E6E6E6;" \| N/A \|style="background:#E6E6E6;" \| Invalid name, ''Belinurus'' (Bronn, 1839) has priority.<ref name="beli" /> \|- \|style="background:#E6E6E6;" \| ~~\| '''''[[Carcinoscorpius]]'''''<ref name="phylogenyarchive"/> \|\| Pocock \|\| 1902~~ †''[[Bifarius]]'' \|style="background:#E6E6E6;" \| Tasch \|style="background:#E6E6E6;" \| [[1961 in paleontology\|1961]] \|style="background:#E6E6E6;" \| Misidentification \|style="background:#E6E6E6;" \| N/A \|style="background:#E6E6E6;" \| N/A \|style="background:#E6E6E6;" \| Misidentified, an [[insect]]. \|- \| ''[[Carcinoscorpius]]'' ~~\| †''[[Casterolimulus]]''<ref name="sepkoski"/> \|\| Holland, Erickson & O'Brien \|\| [[1975 in paleontology\|1975]]~~ \|Pocock \|1902 \|Valid \|???
