'''''Adelphailurus''''' is an extinct [[Biology:Genus|genus]] of [[Biology:Metailurini|metailurin]] machairodontine (saber-toothed) [[Biology:Felidae|cat]] that inhabited western [[Earth:North America|North America]] during the middle Pliocene. It is monotypic, containing only the species '''''Adelphailurus kansensis'''''.<ref name=Hibbard1934/><ref>{{cite book |last1=Turner |first1=Alan |last2=Antón |first2=Mauricio |year=1997 |title=The Big Cats and their fossil relatives |location=New York |publisher=Columbia University Press |isbn=0-231-10228-3}}</ref>

==History of discovery==
The holotype and only specimen, '''KUMVP 3462''', was collected by H. T. Martin from near the base of the Ogallala Formation in Sherman County, {{wipe|Kansas}}, in the summer of 1924. It was subsequently stored in the collections at the University of Kansas' Museum of Vertebrate Paleontology. However, it was not described until 1934 when paleontologist Claude W. Hibbard erected the new genus and species ''Adelphailurus kansensis'' for the specimen.<ref name=Hibbard1934>{{Cite journal|last1=Hibbard |first1=C. W. |date=1934 |title=Two new genera of Felidae from the middle Pliocene of Kansas |journal=Transactions of the Kansas Academy of Science |volume=37 |pages=239–255 |doi=10.2307/3625308 |jstor=3625308 |url=https://www.jstor.org/stable/pdf/3625308.pdf}}</ref>

The genus name is derived from the Greek {{lang|grc|ἀδελφός}}/{{transl|grc|adelphós}} meaning "brother", and {{lang|grc|αἴλουρος}}/{{transl|grc|ailurus}} meaning "cat". The specific epithet ''kansensis'' means "from Kansas".<ref name=Hibbard1934/>

==Description==
The holotype of ''Adelphailurus kansensis'' consists of the anterior portion of a skull with nearly perfect dentition on both the maxillaries and premaxillaries. Hibbard stated that the living cat would have a relatively broad skull with large canines.<ref name=Hibbard1934/>

==Classification==
Hibbard only assigned the genus to the family Felidae in his original description.<ref name=Hibbard1934/> It was assigned to the tribe [[Biology:Metailurini|Metailurini]] in 1983,<ref>{{Cite journal|last1=Berta |first1=A. |last2=Galiano |first2=H. |date=1983 |title=Megantereon hesperus from the late Hemphillian of Florida with remarks on the phylogenetic relationships of machairodonts (Mammalia, Felidae, Machairodontinae) |journal=Journal of Paleontology |volume=57 |issue=5 |pages=892–899 |jstor=1304759}}</ref> assigned in passing to Felidae by Carroll in 1988,<ref>{{Cite journal|last1=Carroll |first1=R.

In 2005, Werdelin and Andersson suggested that ''Adelphailurus kansensis'' should be reassigned to the genus ''[[Biology:Metailurus|Metailurus]]'' as ''Metailurus kansensis'',<ref>{{cite journal |last1=Andersson |first1=K. |last2=Werdelin |first2=L. |date=2005 |title=Carnivora from the late miocene of Lantian, China |url=http://ivpp.cas.cn/cbw/gjzdwxb/xbwzxz/200810/W020090813368770778229.pdf |journal=Vertebrata PalAsiatica |volume=43 |issue=4 |pages=267 |doi= |access-date=}}</ref> but this was rejected and refuted by Li in 2014 and Spassov & Geraads in 2015.<ref>{{cite journal |last1=Li |first1=Yu |date=2014 |title=Restudy of Metailurus major from Yushe Basin, Shanxi Province reported by Teilhard de Chardin and Leroy |url=https://www.researchgate.net/publication/271020687 |journal=Vertebrata PalAsiatica |volume=52 |issue=4 |pages= |doi= |access-date=}}</ref><ref>{{cite journal |title=A New Felid from the Late Miocene of the Balkans and the Contents of the Genus ''Metailurus'' Zdansky, 1924 (Carnivora, Felidae) |date=2014-05-15 |doi=10.1007/s10914-014-9266-5 |volume=22 |journal=Journal of Mammalian Evolution |pages=45–56 |last1=Spassov |first1=Nikolai|s2cid=14261386 |last2=Geraads |first2=Denis}}</ref>

In 2010 it was suggested that ''[[Biology:Nimravides|Nimravides]] hibbardi'' was a junior synonym of ''Adelphailurus kansensis''.<ref>{{Cite journal|last1=Hodnett|first1=John-Paul|date=2010|title= A Machairodont felid (Mammalia; Carnivora; Felidae) from the latest Hemphillian (Late Miocene/Early Pliocene) Bidahochi Formation, northeastern Arizona|journal= Paleobios|volume= 29|issue= 3|pages= |doi=10.5070/P9293021800|url=https://escholarship.org/uc/item/4xr1s918|doi-access=free}}</ref>
