Archaeornithura

Magacu wuxuu ka dhigan yahay: “ornithuromorph hore”1

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

Archaeornithura wuxuu ahaa shimbir yar oo noolaa qiyaastii 130 milyan oo sano ka hor. Waa qaraabadii ugu da'da weynaa ee la yaqaan ee dhammaan shimbiraha casriga ah. Shimbirkan yar wuxuu lahaa baalal wuxuuna awooday inuu si fiican u duulo, sida shimbiraha maanta.2 1

Xaqiiqooyin xiiso leh

Archaeornithura waa ornithuromorph-kii ugu da'da weynaa ee la yaqaan, kooxda ay ku jiraan dhammaan shimbiraha nool.2 1

Wuxuu noolaa 130.7 milyan oo sano ka hor, taas oo qiyaastii 5 ilaa 6 milyan oo sano ka weyn ornithuromorph kasta oo kale oo la yaqaan.1

Shimbirkan wuxuu lahaa alula oo si fiican u horumaray, oo ah far yar oo baalal leh oo ku taal geeska hore ee baalkiisa taas oo ka caawisa inuu si fiican u duulo.2

Archaeornithura wuxuu lahaa baalal dabo oo u samaysan sida taageere iyo furcula (laf-rajo) oo u samaysan sida U, astaamo lagu arko shimbiraha casriga ah.2

Laba xabo oo keliya oo Archaeornithura ah ayaa la helay, labaduba waxay ka yimaadeen Huajiying Formation oo ku yaalla Shiinaha.2 1

Helitaankeedu wuxuu dib u dhigay markii ugu horreysay ee ay soo baxaan shimbiraha ornithuromorph qiyaastii 6 milyan oo sano.1

Sawirka Archaeornithura oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Archaeornithura 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: Archaeornithura
Waxaa magacaabay: Wang et al. 20153
Koox: Shimbiraha hore (xilligii dinos-ka)
Qoyska / kooxda: Hongshanornithidae3
Kala soocidda: Theropoda > Avialae3
Xilligii dhagaxyada: 133 ilaa 126 milyan oo sano (Hauterivian)3
Dhagaxyada: Huajiying3
Waddamada: China3
Diiwaanka fossil-ka: 1 oo ku jira Paleobiology Database3
Daahfurka: Archaeornithura waxaa magacaabay sannadkii 2015 koox uu hoggaaminayay Wang Min iyo Zhou Zhonghe. Fossil-ka waxaa laga soo iibsaday ganacsade fossil ah wuxuuna ka yimid Huajiying Formation ee Hebei, Shiinaha.2 1
Wali waa la isku khilaafsan yahay: Saynisyahannadu weli waxay ku doodayaan sida dhabta ah ee Archaeornithura uu ula xidhiidho shimbiraha kale ee hore iyo haddii uu ahaa shimbir biyaha dhex socota sida qaraabadiisa.1
