Dunhuangia
Dunhuangia waxa uu ahaa shimbir ku noolaa xilligii Early Cretaceous, qiyaastii 121 ilaa 113 milyan oo sano ka hor. Waxa uu ahaa shimbir enantiornithine ah oo cabbirkiisu dhexdhexaad yahay, koox aad ugu badnayd xilligii dinosaurs-ka. Dunhuangia waxa uu lahaa lafo gaar ah oo ku yaal laabtiisa kuwaas oo ka dhigay mid ka duwan shimbiraha kale.21
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Dunhuangia waa shimbirka kaliya ee labaad ee enantiornithine ah oo waligii laga magacaabay Dooxada Changma ee Shiinaha.1
Laftiisa waxaa ku jira qaybo ka mid ah gacmaha hore, garabka, iyo lafta laabta, laakiin madaxa ayaa ka maqan.3
Dhamaadka lafta laabtiisa waxay lahayd jeexdin qoto dheer oo leh laba saadaal oo dhinac ah, taas oo ah muuqaal ka caawiya saynisyahannada inay ka soocaan shimbiraha kale ee enantiornithine.1
Dunhuangia waxa uu la noolaa xayawaano kale oo badan, oo ay ku jiraan kalluun, salamanders, qoolley, iyo shimbiraha kale sida Gansus.1
Dooxada Changma ee laga helay Dunhuangia waa mid ka mid ah meelaha yar ee shimbiraha ornithuromorph ee horumarsan ay ka badnaayeen enantiornithines sida Dunhuangia.1
Saynisyahannadu waxay u maleynayaan in Dunhuangia uu ahaa shimbir dhulka ku nool oo si firfircoon u duuli karay.2

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu weli way ku doodayaan in shimbiraha Changma ay matalaan marxalad kala guur ah oo ay shimbiraha ornithuromorph ka sarreeyaan enantiornithines sida Dunhuangia.1
