Antarcticavis
Antarcticavis wuxuu ahaa shimbir hore oo ku noolaa Antarctica xilligii dinosaurs-ka. Wuxuu la ekaa duck casri ah wuxuuna u badan yahay inuu cunto ka raadsan jiray xeebaha. Shimbirkan waa mid ka mid ah kuwa ugu da'da weyn ee laga yaqaan qaaradda barafka ah.21
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Antarcticavis wuxuu noolaa qiyaastii 72 ilaa 66 milyan oo sano ka hor, xilligii Maastrichtian ee Late Cretaceous.3
Magaceedu wuxuu ka dhigan yahay 'shimbirta Antarctica' sababtoo ah lafaheeda waxaa laga helay Antarctica.1
Saynisyahannadu ma hubo meesha saxda ah ee Antarcticavis kaga jirto qoyska shimbiraha. Qaar waxay u maleynayaan inay u dhowdahay shimbiraha casriga ah, halka kuwa kalena ay la dhigaan shimbiraha biyaha sida loons iyo ducks.1
Lafaha kaliya ee la yaqaan ee Antarcticavis waa qayb ka mid ah lafaha jirka, oo ay ku jiraan qaybo ka mid ah baalasha, lugaha, iyo laf-dhabarta.1
Antarcticavis waa shimbirtii ugu da'da weyneyd ee abid laga sharraxo Antarctica.2
Daraasad la sameeyay sannadkii 2025 ayaa lagu ogaaday in Antarcticavis ay lahayd lafo la mid ah shimbiraha casriga ah ee quusa, sida mergansers iyo gulls, taas oo soo jeedinaysa inay ahayd dabaasha wanaagsan.1

?Antarcticavis ma dabaalan karay?
Haa, waxay u badan tahay inuu ahaa dabaasha wanaagsan. Daraasad la sameeyay sannadkii 2025 ayaa lagu ogaaday in lafaheedu ay la mid yihiin kuwa shimbiraha casriga ah ee quusa sida mergansers iyo gulls.1
?Maxuu cuni jiray Antarcticavis?
Saynisyahannadu ma hubo waxa uu cuni jiray, laakiin waxay u badan tahay inuu cunto ka raadsan jiray xeebaha Antarctica.1
?Antarcticavis ma wuxuu ahaa dinosaur?
Haa, Antarcticavis waa dinosaur. Dhammaan shimbiraha waa xubno ka mid ah kooxda dinosaur-ka, gaar ahaan theropod dinosaurs.1

Rex wuu gaajaysan yahay! Dino Wiki waa mashruuc aabbe u sameeyay wiilkiisa dino-jecel, bilaash ah oo aan lahayn xayeysiis iyo qalab raad-raac. Dadka waaweyn waxay Rex siin karaan cunto fudud si ay uga caawiyaan inuu khadka ku sii jiro.Quudi Rex
