Mengciusornis
Mengciusornis wuxuu ahaa shimbir hore oo ku noolaa Shiinaha xilligii dinosaurs-ka. Wuxuu lahaa ilko fiiqan oo qaloocan oo ku yaalla afkiisa sare, laakiin qaybta kale ee afkiisa waxay ahayd mid aan ilko lahayn. Xayawaankan yar wuxuu awooday inuu duulo wuxuuna u badnaa inuu ugaarsado cayayaanka iyo xayawaanka yaryar.12
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Mengciusornis wuxuu lahaa ilko kaliya qaybta hore ee daankiisa sare, oo loo yaqaan premaxilla. Qaraabadiisa dhow ee Schizooura wax ilko ah haba yaraatee uma lahayn.12
Fosilkii kaliya ee la yaqaan ee Mengciusornis waa laf dhabar si fiican loo ilaaliyay oo xitaa muujinaya haraaga baalasha.1
Mengciusornis wuxuu noolaa qiyaastii 121 ilaa 113 milyan oo sano ka hor, xilligii Early Cretaceous.3
Magaciisu wuxuu sharfayaa faylasuufkii hore ee Shiinaha Mencius, 'dentatus' na wuxuu la macno yahay 'ilko leh' afka Laatiinka.1
Mengciusornis wuxuu lahaa laf-dhuun u qaabaysan V (furcula) iyo laf weyn oo leydi ah oo ku taal lafta gacantiisa sare.2
Saynisyahannadu waxay u malaynayaan in luminta ilkaha ee shimbiraha hore ay ku dhacday siyaabo kala duwan kooxo kala duwan. Mengciusornis wuxuu muujinayaa qaab gaar ah oo qaybta hore ee daanka sare ay ilkaha u haysteen halka inta kale ee afka ay lumiyeen.2

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu weli waxay ku doodayaan sida saxda ah ee Mengciusornis ula xiriirto shimbiraha kale ee hore iyo sida luminta ilkaha ay ugu horumartay qoyskiisa.2

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
