Archaeornithura

Igama lisho ukuthi: “i-ornithuromorph yakudala”1

Udla: InyamaIzinyoni zakuqalaEarly Cretaceous

I-Archaeornithura yayiyinyoni encane eyayiphila eminyakeni eyizigidi ezingu-130 edlule. Yisihlobo esidala kunazo zonke esaziwayo sazo zonke izinyoni zanamuhla. Le nyoni encane yayinoboya futhi yayikwazi ukundiza kahle, njengezinyoni zanamuhla.2 1

izinto ezinhle

Amaqiniso amnandi

I-Archaeornithura iyona i-ornithuromorph endala kunazo zonke eyaziwayo, iqembu elihlanganisa zonke izinyoni eziphilayo.2 1

Yayiphila eminyakeni eyizigidi ezingu-130.7 edlule, okuyiminyaka eyizigidi ezingu-5 kuya kwezingu-6 ubudala kunanoma iyiphi enye i-ornithuromorph eyaziwayo.1

Le nyoni yayinomunwe omncane onoboya onqenqemeni lwangaphambili lwephiko layo osiza ekulawuleni ukundiza.2

I-Archaeornithura yayinoboya bomsila obunjengefeni nethambo eliyisigqoko (wishbone) elinjengohlamvu u-U, izici ezibonakala ezinyonini zanamuhla.2

Kutholakale izinsalela ezimbili kuphela ze-Archaeornithura, zombili zivela ku-Huajiying Formation e-China.2 1

Ukutholakala kwayo kwabuyisela emuva ukubonakala kokuqala kwezinyoni i-ornithuromorph ngeminyaka ecishe ibe ngu-6 million.1

Isithombe sika-Archaeornithura 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.

Igama lesayensi: Archaeornithura
Iqanjwe ngu: Wang et al. 20153
Iqembu: Izinyoni zakuqala
Umndeni / i-clade: Hongshanornithidae3
Ukuhlukaniswa: Theropoda > Avialae3
Inkathi yamadwala: 133 kuya ku-126 wezigidi zeminyaka (Hauterivian)3
Izakhiwo zamatshe: Huajiying3
Amazwe: I-China3
Izinsalela ezitholiwe: 1 ku-Paleobiology Database3
Ukutholakala: I-Archaeornithura yaqanjwa ngonyaka ka-2015 yiqembu eliholwa ngu-Wang Min no-Zhou Zhonghe. Izinsalela zathengwa kumthengisi wezinsalela futhi zavela e-Huajiying Formation e-Hebei, e-China.2 1
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi i-Archaeornithura ihlobene kanjani nezinye izinyoni zakuqala nokuthi yayiyinyoni yasemanzini yini njengezihlobo zayo.1

Yonke imininingwane ekuleli khasi inenombolo ekhomba umthombo wayo. Uma kukhona esikwenze kabi, siyaxolisa, singabalandeli bama-dino, hhayi iphephabhuku lesayensi. Sitshele ku-[email protected] futhi sizokulungisa.
