Piscivorenantiornis
Piscivorenantiornis wuxuu ahaa shimbir yar oo ku noolaa Shiinaha qiyaastii 120 milyan oo sano ka hor. Wuxuu jeclaa cunista kalluunka wuxuuna xitaa matagi jiray kubbad lafaha kalluunka ah, sida shimbiraha qaar ay sameeyaan maanta!12
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Waa shimbirtii ugu horreysay ee enantiornithine ah ee la ogaado inay kalluunka cunto.1
Qalfoofkii ugu horreeyay waxaa laga helay isagoo leh tuulmo lafo kalluun ah oo ku jirta aagga caloosha, laga yaabee inay tahay kubbad uu rabay inuu matago.1
Miskihiisa (lafaha sinta) ayaa gebi ahaanba isku dhegay, taas oo naadir u ah shimbiraha hore ee Cretaceous. Kaliya laba ama saddex shimbirood oo kale oo enantiornithines ah ayaa wadaaga astaantan.2
Sternum-ka (lafta naaska) wuxuu lahaa qodax gaar ah oo xagga hore ah oo shimbiraha kale ee enantiornithines aysan lahayn.1
Mid ka mid ah lafaha qoorta ayaa lahaa qaab qariib ah: wuxuu u qaloocnaa kor iyo hoos hal dhinac, iyo dhinac ilaa dhinac kale. Ma jiro shimbir kale oo leh taas.3
Qalfoof labaad oo shimbirtan ah ayaa la helay 2020, taas oo siinaysa saynisyahannada tilmaamo dheeraad ah oo ku saabsan sida ay u noolaayeen.1
Wuxuu noolaa intii lagu jiray xilligii Aptian, qiyaastii 121 ilaa 113 milyan oo sano ka hor.4

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu weli ma hubo sababta lafta qoorta ay u leedahay qaabkan qariibka ah, oo aan la mid ahayn shimbir kale.3

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
