Ikhadi le-Dino No. 1484 kwangu-2 027

Protoavis

Igama lisho ukuthi: “inyoni yokuqala”1

Udla: InyamaAma-dino adla inyamaLate Triassic

I-Protoavis yayiyidinaso encane edla inyama eyayiphila endaweni esiyi-Texas namuhla, e-USA, eminyakeni eyizigidi ezingaba ngu-210 edlule. Yayinamazinyo abukhali namehlo amakhulu ngaphambili ogebhezini lwayo, okwayisiza ukuthi ibone kahle ebumnyameni. Abanye ososayensi bacabanga ukuthi kungenzeka yayiyinyoni yakuqala, kodwa abaningi bayaphikisana nalokho.1

izinto ezinhle

Amaqiniso amnandi

I-Protoavis yayiphila eminyakeni eyizigidi ezingaba ngu-210 edlule, okuyiminyaka eyizigidi ezingama-60 kuya kwezingama-75 ngaphambi kwenyoni yakuqala edumile i-Archaeopteryx.1

Izinsalela ze-Protoavis zatholakala enqwabeni yamathambo axubene, okungenzeka ukuthi kwabangelwa uzamcolo owabulala izilwane eziningi ngesikhathi esisodwa.1

I-Protoavis yayinamehlo ngaphambili kwekhanda layo, okwayinika amandla okubona ngezinto ezimbili ngesikhathi esisodwa (binocular vision) futhi kusikisela ukuthi kungenzeka yayisebenza ebusuku noma ngesikhathi sokushona kwelanga.1

Izinsalela zokuqala ze-Protoavis zatholakala ngonyaka ka-1973 futhi ekuqaleni kwakucatshangwa ukuthi ziyidinosaur encane i-Coelophysis.1

Osayensi abaningi bayangabaza ukuthi i-Protoavis iyinyoni yangempela, ngoba amathambo aphukile kakhulu futhi exubene kangangokuba akunakwenzeka ukuqiniseka ukuthi ayingxenye yohlobo olulodwa.1

I-Protoavis yaqanjwa yisazi sezinsalela u-Sankar Chatterjee ngonyaka ka-1991, owayecabanga ukuthi iyinyoni yakuqala evela e-Texas.1

Isithombe sika-Protoavis 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-Protoavis

?Ingabe i-Protoavis iyidinosaur?

Osayensi abaningi bacabanga ukuthi i-Protoavis iyisilwane esihuquzelayo sasendulo, kodwa abaqiniseki ukuthi iyinyoni noma ingxube yezilwane ezahlukene. Leli khasi liyibiza ngokuthi i-theropod edla inyama.1

?Yayinkulu kangakanani i-Protoavis?

I-Protoavis yayingaba ngamasentimitha angu-35 ubude, ngokwesazi esayichaza okokuqala. Lokho kulingana nobude berula.1

?Ingabe i-Protoavis yayinoboya?

Abanye osayensi bacabanga ukuthi yayinoboya ngenxa yezigaxa emathanjeni ayo engalo, kodwa abanye abaqiniseki. Azikho izimpawu zoboya ezitholakele.1 2

?Ingabe i-Protoavis yayikwazi ukundiza?

Ukube yayiyinyoni, kungenzeka yayikwazi ukundiza isuka esihlahleni iye kwesinye kodwa hhayi amabanga amade. Nokho, osayensi abaningi bayangabaza ukuthi yayiyinyoni nhlobo.2

?I-Protoavis yaphila nini?

I-Protoavis yayiphila eminyakeni eyizigidi ezingaba ngu-210 edlule, ngesikhathi se-Late Triassic. Lokho kuyiminyaka eyizigidi ezingama-60 kuya kwezingama-75 ngaphambi kwe-Archaeopteryx.1

?Yini eyayidliwa yi-Protoavis?

I-Protoavis yayidla inyama. Yayinozinyo ababukhali ekugcineni kwemihlathi yayo ukuze ibambe inyamazane.1

Buza u-Rex ngo-Protoavis

Rex uphendula imibuzo mayelana naleli khasi kuphela. Imibuzo engu-10 ngenyanga.

Rex uyi-AI futhi angenza amaphutha. Usebenza kumaseva ase-EU futhi imibuzo ayilokothi ilondolozwe. Ungalokothi uthayiphe igama lakho noma ezinye izinto zakho.

Umchithi wezinganekwane

Inganekwane: I-Protoavis iyinyoni endala kunazo zonke eyaziwayo.

Iqiniso: Izazi eziningi zezinsalela (paleontologists) ziyangabaza ukuthi i-Protoavis iyinyoni nhlobo. Izinsalela ziphukile kakhulu futhi zixubene kangangokuba akunakwenzeka ukuqiniseka ukuthi zivela esilwaneni esisodwa esifana nenyoni.1

Ochwepheshe bama-dino

Igama lesayensi: Protoavis

Ukutholakala: I-Protoavis yaqanjwa ngu-Sankar Chatterjee ngonyaka ka-1991 ngokusekelwe ezinsaleleni ezatholakala e-Dockum Group yase-Texas, e-USA, ngonyaka ka-1973 nango-1984. Amathambo atholakala endaweni yodaka okungenzeka yakheka ngemva kukazamcolo.1
Kusaphikiswana ngakho: Osayensi basaphikisana ngokuthi i-Protoavis iyinyoni, iyidinosaur, noma ingxube yezilwane ezahlukene, ngoba izinsalela ziphukile futhi aziphelele.1

Rex ulambile! I-Dino Wiki iphrojekthi kababa wendodana yakhe ethanda ama-dino, imahhala ngaphandle kwezikhangiso nezilandeleli. Abantu abadala bangaphakela u-Rex ukudla okulula ukuze basize ukuyigcina iku-inthanethi.Phakela u-Rex
