Sulcavis
Sulcavis wuxuu ahaa shimbir yar oo ilko leh oo noolaa xilligii dinosaurs-ka. Wuxuu lahaa jeexdin gaar ah oo ku yaal ilkahiisa, taas oo aysan lahayn shimbir kale. Tani waxay ka caawisay inuu cuno cuntooyin adag sida cayayaanka qallafsan ama miraha.12
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Sulcavis waa shimbirtii ugu horreysay ee abid la helo oo leh dhaldhalaal ilko oo qurxoon. Ilkahiisu waxay lahaayeen jeexdin gudaha ah oo ka dhigtay kuwo aad u adag.12
Wuxuu noolaa qiyaastii 121 ilaa 125 milyan oo sano ka hor xilligii Early Cretaceous.1
Sulcavis wuxuu ka tirsanaa koox shimbiraha qadiimiga ah oo la yiraahdo enantiornitheans, kuwaas oo weli lahaa ilko iyo cidiyo si ka duwan shimbiraha casriga ah.1
Fosillada waxaa laga helay Yixian Formation, oo ah lakab dhagax caan ah oo ku yaal Shiinaha kaas oo ilaaliyay dinosaurs badan oo baalal leh iyo shimbiraha hore.1
Magaciisu wuxuu ka yimid ereyo Laatiin ah oo macnahoodu yahay 'shimbirta jeexdin leh', sababtoo ah jeexdinka ku yaal ilkahiisa.1

- Sulcavis waxaa magacaabay sanadkii 2013 koox saynisyahanno ah oo ay ku jirto Jingmai O'Connor. Fosillada waxaa laga helay meel u dhow Lamadong ee Liaoning, Shiinaha, waxaana diyaariyay Maureen Walsh oo ka tirsan Matxafka Taariikhda Dabiiciga ah ee Degmada Los Angeles.1
- Wali waa la isku khilaafsan yahay
- Saynisyahannadu si dhab ah uma hubo waxa uu cuni jiray Sulcavis, laakiin ilkaha adag ee jeexdin leh ayaa soo jeedinaya inuu awooday inuu cuno cunto ka adag tan shimbiraha kale ee hore.12

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
