Gretcheniao
I-Gretcheniao kwakuyinyoni encane enezimpaphe eyayiphila eminyakeni eyizigidi ezingu-125 edlule kuleyo ndawo okuyizwe lase-China manje. Yayinozinyo oluqinile nezinzipho ezibukhali, futhi kungenzeka ukuthi yayizingela ukudla phansi. Le nyoni yayikwazi ukundiza, kodwa hhayi amabanga amade kakhulu!32

Amaqiniso amnandi
I-Gretcheniao yayinethambo lesandla elide kakhulu elibizwa ngokuthi i-carpometacarpus, elide kunalawo wonke ezihlobo zayo, nakuba ithambo layo lengalo eliphezulu lalingelesithathu ngobukhulu.1
Ithambo layo lesifuba lalinemikhono ekhethekile eyayikhomba emuva nangaseceleni, okwasiza ukusekela imisipha yayo yokundiza.1
Izinzipho ze-Gretcheniao zazinde, zigobile, zilungele ukubamba amagatsha noma inyamazane.1
Ososayensi bacabanga ukuthi i-Gretcheniao yayindiza ngokushaya amaphiko ayo ngokuqhubekayo, kodwa yayingakwazi ukundiza amabanga amade, okufana nezinkukhu noma izigwaca zanamuhla.21
Insalela ye-Gretcheniao yayigcineke kahle kakhulu kangangokuba ezinye zezimpaphe zayo zashiya izimpawu ezimnyama edwaleni, ikakhulukazi entanyeni nasemaphikweni ayo.1
IGretcheniao yayinomlomo oqinile nomhlathi ongezansi oqinile, okuyinto eyayisiza ukuba ilume ukudla okuqinile.1
Umchithi wezinganekwane
Inganekwane: Abanye abantu bacabanga ukuthi i-Gretcheniao yayiyidinosaur efana ne-T. rex, kodwa empeleni yayiyinyoni.
Iqiniso: I-Gretcheniao yayiwuhlobo lwenyoni ebizwa ngokuthi i-enantiornithine, okuyiqembu lezinyoni zasendulo ezaziphila kanye namadinosaur. Izinyoni zihlobene namadinosaur, kodwa azifani nezilwane ezinkulu ezidla inyama.31

- I-Gretcheniao yaqanjwa ngonyaka ka-2019 ngososayensi ababefunda ithambo elicishe liphelele elatholakala e-China. Le nsalela yaqanjwa ngemva kuka-Nkk. Gretchen Augustyn, owayesekela i-Dinosaur Institute, kanti 'sinensis' kusho 'yase-China'.1
- Kusaphikiswana ngakho
- Ososayensi basaphikisana ngokuthi i-Gretcheniao nezihlobo zayo eziseduze zihlobene kanjani. Abanye bacabanga ukuthi zonke zingeyeqembu elilodwa, kodwa abanye bacabanga ukuthi zavela ngokuhlukana.21

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.
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
