Yuanjiawaornis

Igama lisho ukuthi: “inyoni evela e-Yuanjiawa”1

Udla: InyamaIzinyoni zakuqalaEarly Cretaceous

I-Yuanjiawaornis yayiyinyoni enkulu, enamandla eyayiphila eminyakeni engaba yizigidi eziyi-120 edlule endaweni manje eyi-China. Yayingenye yezinyoni ezinkulu kakhulu zangesikhathi sayo, enamaphiko acishe abe uhhafu wemitha ububanzi. Cishe yayizingela izilwane ezincane ukuze idle.1 2

izinto ezinhle

Amaqiniso amnandi

I-Yuanjiawaornis yaziwa ngohlaka lwamathambo olucishe luphelele ngaphandle kugebhezi, olwatholakala ngo-2005 ngusosayensi wezinsalela eduze kwesigodi sase-Yuanjiawa.1

Izinyoni eziningi ze-enantiornithine zazincane njengonogwaja noma izinkanyezi, kodwa i-Yuanjiawaornis yayinkulu kakhulu, cishe ilingana ne-Zhouornis.1 2

Isinsalela se-Yuanjiawaornis asinalo izimpaphe ezilondoloziwe, okuyinto engajwayelekile ezinsaleleni zezinyoni ezivela e-Liaoning.1

I-Yuanjiawaornis yayiphila ngenkathi ye-Early Cretaceous, eminyakeni engaba yizigidi eziyi-120 edlule, e-Jiufotang Formation.1 3

Isampula le-holotype cishe lalingumuntu omdala osemusha, ngoba amathambo esihlakala salo ayengakahlanganiseki ngokuphelele.2

I-Yuanjiawaornis yayinohlobo olukhethekile lwe-synsacrum (ingxenye ehlanganisiwe yomgogodla) engase ibe yinto ekhethekile ezinyonini ze-enantiornithine.2

Isithombe sika-Yuanjiawaornis esenziwe nge-AI sokuthi kungenzeka ukuthi wayebukeka kanjani, senziwe yikhompyutha ngokusekelwe kulokho okwaziwa ososayensi. Lokhu kuwukuqagela: isilwane sangempela kungenzeka ukuthi sasibukeka ngokuhlukile, futhi akekho owazi imibala yaso yangempela.

Ochwepheshe bama-dino

Igama lesayensi: Yuanjiawaornis
Iqanjwe ngu: Hu et al. 20154
Iqembu: Izinyoni zakuqala
Umndeni / i-clade: Enantiornithes4
Ukuhlukaniswa: Theropoda > Avialae4
Inkathi yamadwala: 121 kuya ku-113 wezigidi zeminyaka (Aptian)4
Izakhiwo zamatshe: Jiufotang4
Amazwe: I-China4
Izinsalela ezitholiwe: 1 ku-Paleobiology Database4
Ukutholakala: I-Yuanjiawaornis yaqanjwa ngo-2015 ngu-Hu Dongyu nozakwabo ngokusekelwe kuhlaka lwamathambo olwatholakala ngo-2005 eduze kwesigodi sase-Yuanjiawa e-Liaoning, e-China.1 2
Kusaphikiswana ngakho: Ososayensi abaqiniseki ukuthi i-Yuanjiawaornis ihlobene kanjani nezinye izinyoni ze-enantiornithine, ngoba ugebhezi lwayo alutholakali.1
