Yatenavis

Magacu wuxuu ka dhigan yahay: “shimbir dhagax ah”1

Cunay: HilibShimbiraha hore (xilligii dinos-ka)Cretaceous-kii dambe

Yatenavis wuxuu ahaa shimbir yar oo noolaa dhamaadkii xilligii dinosaurs-ka. Wuxuu la ekaa shimbirta sparrow-ga, wuxuuna ku duuli jiray kaymaha meesha hadda loo yaqaan Patagonia ee Argentina. Shimbirtan yar waa mid ka mid ah shimbiraha enantiornithine ee ugu koonfureed ee abid la helo.2 1

Xaqiiqooyin xiiso leh

Yatenavis waxaa lagu yaqaanaa hal laf oo keliya: qaybta hoose ee lafta baalka midig (humerus).2 1

Wuxuu noolaa qiyaastii 72 ilaa 66 milyan oo sano ka hor, xilligii Maastrichtian ee dhamaadkii Cretaceous.3

Yatenavis waa shimbirta enantiornithine ee ugu koonfureed ee abid laga helo meel kasta oo adduunka ah.2 1

Wuxuu ahaa mid ka mid ah shimbiraha enantiornithine ee ugu yar ee laga helo dhamaadkii Cretaceous ee Koonfurta Ameerika, wuxuuna la ekaa shimbirta sparrow-ga.2 1

Magaciisu wuxuu ka yimid ereyga Aoni Kenk ee 'dhagax' iyo Laatiinka 'shimbir', taas oo macnaheedu yahay 'shimbir dhagax ah'.1

Yatenavis wuxuu la noolaa shimbiraha kale, oo ay ku jiraan enantiornithine ka weyn iyo shimbir la yiraahdo Kookne yeutensis.1

Laf-dhabarta waxaa laga helay Chorrillo Formation, oo ay samaysay nidaamka webiga ee deegaan qabow oo sareeya.2 1

Sawirka Yatenavis oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Yatenavis u ekaan karay, oo uu kombuyuutarku ka sameeyay waxa ay saynisyahannadu yaqaaniin. Waa qiyaas: xayawaanka dhabta ah waxaa laga yaabaa inuu u ekaa si ka duwan, qofna ma garanayo midabadiisa dhabta ah.

Khubarada dino

Magaca sayniska: Yatenavis
Waxaa magacaabay: Álvarez Herrera et al. 20233
Koox: Shimbiraha hore (xilligii dinos-ka)
Qoyska / kooxda: Enantiornithes3
Kala soocidda: Theropoda > Avialae3
Xilligii dhagaxyada: 72 ilaa 66 milyan oo sano (Maastrichtian)3
Dhagaxyada: Chorrillo3
Waddamada: Argentina3
Diiwaanka fossil-ka: 1 oo ku jira Paleobiology Database3
Daahfurka: Yatenavis waxaa magacaabay oo sharraxay sanadkii 2023 koox saynisyahanno reer Argentina iyo Japan ah, oo ay ku jiraan Gerardo Álvarez Herrera iyo Federico Agnolín. Laf keliya ayaa laga helay intii lagu jiray safar wadajir ah bishii Maarso 2022 ee Estancia La Anita ee Patagonia, Argentina.2 1
Wali waa la isku khilaafsan yahay: Saynisyahannadu si dhab ah uma hubo sida uu Yatenavis u ekaa ama sida uu u dhaqmi jiray, sababtoo ah waxaa la helay oo kaliya hal laf oo baal ah.2 1
