Cratoavis waa mid ka mid ah shimbiraha ugu da'da weyn ee lafaha laga helay Koonfurta Ameerika, waxayna noolaayeen qiyaastii 117 milyan oo sano ka hor.2
Lafaheeda waxaa ku jira baalal ku dhegan baalasheeda iyo hareeraha jirkeeda, taas oo muujinaysa qaabka ay u ekayd.1
Lafaha kalluunka oo ka yimid ugu yaraan laba kalluun oo yaryar oo la yiraahdo Dastilbe crandalli ayaa laga helay gudaha caloosha shimbirta.2
Tani waa caddeyntii ugu horreysay ee toos ah oo ku saabsan waxa ay cuni jirtay shimbir kasta oo Mesozoic ah oo ka timid Koonfurta Hemisphere.2
Cratoavis waxay lahayd af dhuuban oo gaaban, laakiin weli way qabsan jirtay oo cuni jirtay kalluunka.2

?Intee in le'eg ayuu ahaa Cratoavis?
Waxay ahayd shimbir aad u yar, oo qiyaastii le'eg shimbirta loo yaqaan sparrow. Lafaha la helay waxay muujinayaan inay lahayd af gaaban iyo baalal dabo oo dhaadheer.13
?Maxuu cuni jiray Cratoavis?
Wuxuu cuni jiray kalluun. Lafaha kalluunka oo ka yimid ugu yaraan laba kalluun oo yaryar oo la yiraahdo Dastilbe crandalli ayaa laga helay gudaha caloosha.21

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
