Vescornis
Vescornis wuxuu ahaa dinosaur yar oo baalal leh oo awooday inuu duulo. Wuxuu noolaa intii lagu jiray xilligii hore ee Cretaceous, qiyaastii 122 milyan oo sano ka hor, meesha hadda loo yaqaan Shiinaha. Shimbirkan yar wuxuu lahaa cidiyo lugood oo dhaadheer iyo faro baalal gaagaaban, taas oo ka dhigtay mid ku fiican duulista laakiin aan aad ugu fiicnayn fuulista geedaha.12
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Vescornis wuxuu lahaa cidiyo baalal oo aad u yar iyo cidiyo cagood oo dhaadheer oo xooggan, kuwaas oo ka caawiyay inuu si fiican u duulo laakiin ka dhigay mid ka liita fuulidda marka loo eego shimbiraha kale ee hore.2
Fosilkii kaliya ee la yaqaan ee Vescornis waxaa markii hore loo maleeyay inuu ka yimid Yixian Formation, laakiin juqraafiyayaashii dambe waxay ogaadeen inuu dhab ahaantii ka yimid Huajiying Formation.1
Vescornis waxaa laga yaabaa inuu yahay isla xayawaankii shimbir kale oo hore oo la yiraahdo Jibeinia, laakiin saynisyahannadu ma hubo sababtoo ah fosilkii Jibeinia waa lumay.1
Magaca 'Hebeiornis' waxaa la siiyay isla fosilkaas sannadkii 1999, laakiin magacaas lama isticmaalo sababtoo ah si fiican looma sharraxin.1
Vescornis wuxuu noolaa qiyaastii 122 milyan oo sano ka hor, xilligii Early Cretaceous.1

Burinta khuraafaadka
Khuraafaad: Dadka qaar waxay u haystaan in Vescornis uu ahaa shimbir dhab ah sida shimbiraha casriga ah.
Runta: Vescornis wuxuu ahaa enantiornithine, oo ah koox shimbirro hore ah oo lahaa ilko iyo cidiyo, mana aha awoowe toos ah oo u dhashay shimbiraha maanta.1

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu weli way isku khilaafsan yihiin in Vescornis uu yahay isla nooc la mid ah Jibeinia, sababtoo ah fosilkii Jibeinia waa lumay labaduna aad bay isugu eg yihiin.1

Xaqiiqo kasta oo boggan ku taal waxay leedahay lambar tilmaamaya halka ay ka timid. Haddii aan wax khaldnay, raali ahow, waxaan nahay taageerayaasha dino, ma nihin joornaal saynis. Noo sheeg [email protected] waana hagaajin doonnaa.
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
