'''''Yatenavis''''' (meaning "stone bird") is an extinct genus of enantiornithine bird from the [[Earth:Late Cretaceous|Late Cretaceous]] [[Earth:Chorrillo Formation|Chorrillo Formation]] of [[Place:Santa Cruz Province, Argentina|Santa Cruz Province]], {{wipe|Argentina}}. The genus contains a single species, '''''Y. ieujensis''''', known from a partial humerus.<ref name=Yatenavis>{{Cite journal |last1=Herrera |first1=Gerardo Álvarez |last2=Agnolín |first2=Federico |last3=Rozadilla |first3=Sebastián |last4=Lo Coco |first4=Gastón E. |last5=Manabe |first5=Makoto |last6=Tsuihiji |first6=Takanobu |last7=Novas |first7=Fernando E. |date=2022-12-16 |title=New enantiornithine bird from the uppermost Cretaceous (Maastrichtian) of southern Patagonia, Argentina |journal=Cretaceous Research |volume=144 |language=en |pages=105452 |doi=10.1016/j.cretres.2022.105452 |s2cid=254804249 |issn=0195-6671}}</ref>

The ''Yatenavis'' [[Biology:Holotype|holotype]] specimen, MPM-PV-23086, was discovered in sediments of the [[Earth:Chorrillo Formation|Chorrillo Formation]] near Estancia La Anita, Calafate, [[Place:Santa Cruz Province, Argentina|Santa Cruz Province]], {{wipe|Argentina}}. This specimen consists of the distal right [[Biology:Humerus|humerus]].<ref name=Yatenavis/>

In 2022, Herrera  ''et al''. [[Biology:Species description|described]] ''Yatenavis ieujensis'', a new genus and species of enantiornithine, based on these fossil remains. The [[Biology:Genus|generic name]], "''Yatenavis''", combines the Aonikenk word for "stone" with the [[Social:Latin|Latin]] word "avis", meaning "bird". The [[Biology:Specific name (zoology)|specific name]], "''ieujensis''", is derived from "ieuj", the Aonikenk word for "snow". ''Yatenavis'' represents the eighth enantiornithine named from South America.<ref name=Yatenavis/>

== Description ==
Herrera ''et al''. (2022) concluded that ''Yatenavis '' would have had a body size comparable to [[Biology:Neontology|extant]] [[Biology:Old World sparrow|sparrow]]s. The fossil material bears similar features to Late Cretaceous enantiornithines from various locations across the world, including {{wipe|Madagascar}}, [[Earth:North America|North America]], [[Place:Patagonia|Patagonia]], and [[Place:Central Asia|Central Asia]].<ref name=Yatenavis/>

== Paleoecology ==
''Yatenavis'' represents the southernmost record of enantiornithines. As enantiornithines are uncommon in high-latitude and cold environments (which were more frequently inhabited by ornithurines), the discovery of ''Yatenavis'' in the Chorrillo Formation is surprising. ''Yatenavis'' coexisted with the ornithurine ''Kookne'' and a large indeterminate enantiornithine.<ref name=Yatenavis/> Non-avian dinosaurs, including the elasmarian [[Biology:Ornithopod|ornithopod]] ''[[Biology:Isasicursor|Isasicursor]]'', the titanosaurian ''[[Biology:Nullotitan|Nullotitan]]'', and the megaraptorid ''[[Biology:Maip|Maip]]'', have also been named from the [[Earth:Chorrillo Formation|Chorrillo Formation]].<ref name=Novas2019>{{Cite journal |last1=Novas |first1=Fernando |last2=Agnolin |first2=Federico |last3=Rozadilla |first3=Sebastián |last4=Aranciaga-Rolando |first4=Alexis |last5=Brissón-Eli |first5=Federico |last6=Motta |first6=Matias |last7=Cerroni |first7=Mauricio |last8=Ezcurra |first8=Martín |last9=Martinelli |first9=Agustin |last10=D´Angelo |first10=Julia |last11=Álvarez-Herrera |first11=Gerardo |date=2019 |title=Paleontological discoveries in the Chorrillo Formation (upper Campanian-lower Maastrichtian, Upper Cretaceous), Santa Cruz Province, Patagonia, Argentina |url=https://www.researchgate.net/publication/337901475 |journal=Revista del Museo Argentino de Ciencias Naturales |series=Nueva Serie |language= |volume=21 |issue=2 |pages=217–293 |doi=10.22179/revmacn.21.655 |s2cid=212808625 |issn=1853-0400|doi-access=free |hdl=11336/122229 |hdl-access=free }}</ref><ref name=Maip>{{Cite journal |last1=Rolando |first1=Alexis M.
