Vegasaurus

Magacu wuxuu ka dhigan yahay: “Qorratada Vega”1

Cunay: HilibPlesiosaursCretaceous-kii dambeSi farsamo ahaan ma aha dinosaur

Vegasaurus wuxuu ahaa xayawaan badeed qoorta dheer oo ku dabaalan jiray badaha qabow ee u dhow Antarctica qiyaastii 72 milyan oo sano ka hor. Ma ahayn dinosaur, laakiin wuxuu ahaa plesiosaur, wuxuuna isticmaali jiray afar baal si uu biyaha ugu dhex dabaasho. Xayawaankan qadiimiga ah waa mid ka mid ah plesiosaurs-ka Late Cretaceous ee laga helay Koonfurta Hemisphere ee laf dhabartiisa si fiican loo yaqaan.2 1

Xaqiiqo xiiso leh: xayawaankan badda ku nool wuxuu dabaalanayay halka dinos-ku ay dhulka ku socdeen. Qof walba wuxuu ugu yeeraa dinos, laakiin waxay ahaayeen qayb kale oo ka mid ah xayawaanka gurguurta.

Xaqiiqooyin xiiso leh

Vegasaurus wuxuu lahaa 54 laf dhabar oo qoorta ah, taas oo ka badan inta badan plesiosaurs-ka kale.1

Fosilka kaliya ee la yaqaan ee Vegasaurus waxaa helay 1989 koox saynisyahanno ah oo ku sugan Jasiiradda Vega, Antarctica.1

Plesiosaur-kan wuxuu lahaa gastroliths, ama dhagaxyada caloosha, kuwaas oo laga yaabo inay ka caawiyeen inuu dheefshiido cuntada ama uu xakameeyo sabayntiisa.1

Vegasaurus waxaa loogu magac daray Jasiiradda Vega, halkaas oo laga helay, iyo ereyga Giriigga ah ee qorratada, 'sauros'.1

Laftiisa humerus (lafta gacanta sare) waxay lahayd jilib hore u jeeda iyo qayb gadaal u soo baxday oo leh dusha sare ee wadajirka ah, taas oo ah muuqaal ay la wadaagaan oo kaliya dhowr plesiosaurs kale.1

Vegasaurus wuxuu si dhow ula xiriiraa plesiosaurs-ka kale ee ka yimid gobolka Weddell Sea, sida Aristonectes iyo Kaiwhekea.2 1

Sawirka Vegasaurus oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Vegasaurus u ekaan karay, oo uu kombuyuutarku ka sameeyay waxa ay saynisyahannadu yaqaaniin. Waa qiyaas: xayawaanka dhabta ah waxaa laga yaabaa inuu u ekaa si ka duwan, qofna ma garanayo midabadiisa dhabta ah.

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
