Parapengornis
Parapengornis wuxuu ahaa shimbir ku noolaa xilligii dinosaurs-ka, qiyaastii 120 milyan oo sano ka hor. Wuxuu lahaa dabo xoog leh iyo cidiyo gaar ah oo ka caawiyay inuu geedaha fuulo sida shimbirta qoryaha garaacda. Shimbirkan yar wuxuu ahaa mid hilibka cuna oo qabsan jiray cayayaanka iyo ugaadhsiga kale ee yaryar.2

Xaqiiqooyin xiiso leh
Parapengornis wuxuu lahaa laf dabo aad u ballaaran oo gaaban (pygostyle) taas oo ka ballaaranayd inta ay dherer ahaan ahayd, taas oo aan caadi ahayn shimbiraha hore.2
Lafaha dabadiisu waxay u ekaayeen kuwa shimbiraha qoryaha garaaca ee casriga ah, markaa saynisyahannadu waxay u malaynayaan in Parapengornis uu fuuli karayay jirridaha geedaha oo uu ku dhegi karayay jilifta.2
Shimbirkan wuxuu lahaa ilko dhaadheer oo dhuuban kuwaas oo ku cidhiidhsanaa salka oo xoogaa qaloocsan gadaal, taas oo ku habboon qabsashada ugaadhsiga simbiriirixan.2
Parapengornis wuxuu ahaa mid ka mid ah shimbiraha ugu waaweyn ee Cretaceous-ka hore ee enantiornithine, oo qiyaastii la'eg shimbirta qawiga ee casriga ah.2
Lafaha Parapengornis waxaa la helay iyadoo ay la socdaan sawirrada baalashiisa baalka iyo dabada, taas oo muujinaysa inuu lahaa baalal duulimaad oo si buuxda u horumaray.2
Wuxuu la noolaa shimbiraha kale ee hore iyo dinosaurs-ka Jehol Biota ee Shiinaha, qiyaastii 120 milyan oo sano ka hor.2

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
