Apsaravis

Udla: InyamaIzinyoni zakuqalaLate Cretaceous

I-Apsaravis yayiyinyoni encane endizayo eyayiphila ogwadule lwase-Mongolia ngesikhathi sezilwane. Yayilingana nejuba futhi yayikwazi ukundiza kahle, isebenzisa amaphiko ayo ukuzingela ukudla phansi.1 2

Ukundiza, isilinganiso

I-Apsaravis yayidla ini?

Ososayensi bacabanga ukuthi i-Apsaravis yayisebenzisa amaphiko ayo ukuzingela ukudla phansi, kodwa ukudla kwayo okuqondile akwaziwa.

izinto ezinhle

Amaqiniso amnandi

I-Apsaravis ingenye yezinyoni ezilondolozwe kahle kakhulu ezivela enkathini ye-Mesozoic, kutholakale uhlaka olucishe luphelele.1

Yaphila eminyakeni engaba izigidi ezingu-83 kuya kwezingu-72 edlule, ngesikhathi se-Campanian se-Late Cretaceous.5

Insalela eyodwa kuphela eyaziwayo ye-Apsaravis yatholakala e-Djadokhta Formation yase-Mongolia, indawo edumile yezinsalela zezilwane.5 1

I-Apsaravis yayinethambo eliqinile engalweni yayo engenhla, okungenzeka ukuthi lasiza ngemisipha enamandla yamaphiko ukuze indize.2

Le nyoni ibalulekile ngoba isiza ososayensi ukuba baqonde ukuthi izinyoni zanamuhla zavela kanjani kubokhokho bazo bezilwane.1

I-Apsaravis iyona kuphela isilwane esifana nenyoni (avialan) esatholakala e-Ukhaa Tolgod ngaphandle kwama-alvarezsaurid aphikisanayo.1

Isithombe sika-Apsaravis 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.

Imibuzo ebuzwa kakhulu mayelana no-Apsaravis

?Ingabe i-Apsaravis yayiyisilwane?

Yebo, i-Apsaravis yayiyisilwane esifana nenyoni. Ingaphansi kweqembu i-Avialae, elihlanganisa zonke izinyoni.3 1

?Yayinkulu kangakanani i-Apsaravis?

I-Apsaravis yayilingana nejuba. Uhlaka lwayo olucishe luphelele lubonisa ukuthi yayiyinyoni encane endizayo.3 4

?I-Apsaravis yayidla ini?

Ososayensi bacabanga ukuthi i-Apsaravis yayisebenzisa amaphiko ayo ukuzingela ukudla phansi, kodwa ukudla kwayo okuqondile akwaziwa.3

?Ingabe i-Apsaravis yayikwazi ukundiza?

Yebo, i-Apsaravis yayikwazi ukundiza kahle. Yayinesici esikhethekile sethambo esandleni sayo esasisiza ekunwetheni amaphiko, okuyisici esibalulekile sokundiza kwezinyoni zanamuhla.3 1

Ochwepheshe bama-dino

Igama lesayensi: Apsaravis
Iqanjwe ngu: Norell and Clarke 20015

Amazwe: Mongolia5
Izinsalela ezitholiwe: 1 ku-Paleobiology Database5
Ukutholakala: I-Apsaravis yaqanjwa ngu-Mark Norell no-Julia Clarke ngonyaka ka-2001, ngokusekelwe kuhlaka olucishe luphelele olwatholakala e-Ukhaa Tolgod e-Mongolia.5 1
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi i-Apsaravis ikuphi emndenini wezinyoni, ikakhulukazi ukuthi ihlobene kakhulu yini nezinyoni zanamuhla noma izinyoni zasendulo ezidiliza emanzini ezifana ne-Hesperornis.1 2
