Brevirostruavis
Brevirostruavis waxay ahayd shimbir yar oo ilko leh oo ku noolayd kaymo qadiimi ah qiyaastii 120 milyan oo sano ka hor. Waxay lahayd san aad u gaaban laakiin carrab aad u dheer, kaas oo ay u badan tahay inay u isticmaali jirtay inay ku qabato cayayaanka ama ay ka nuugto malabka ubaxa.2

Xaqiiqooyin xiiso leh
Brevirostruavis waxay lahayd laf carrab (hyoid) oo ku dhowayd dhererka madaxeeda oo dhan, taas oo ah muuqaal aan lagu arkin shimbiraha kale ee hore.2
Sankeeda gaaban waxaa ku safnaa ilko yaryar oo u qaabaysan biin, kuwaas oo ka caawiyay inay qabsato ugaarta.2
Shimbirtan waxay noolayd xilligii Early Cretaceous, qiyaastii 120 milyan oo sano ka hor, meesha hadda loo yaqaan waqooyi-bari Shiinaha.2
Brevirostruavis waxay ka tirsanayd koox shimbiraha dabar go'ay oo la yiraahdo Enantiornithes, kuwaas oo ahaa shimbiraha ugu kala duwan xilligii Mesozoic.2
Saynisyahannadu waxay u malaynayaan in carrabkeeda dheer uu ka caawiyay inay gaarto cunto aysan shimbiraha kale gaari karin, sida cayayaanka ku dhuumanaya jilifka geedaha ama malabka ubaxa ee qoto dheer.2
Si ka duwan shimbiraha casriga ah, Brevirostruavis waxay u badan tahay inaysan dhaqaajin karin afkeeda sare, markaa waxay ahayd inay carrabkeeda ku tiirsanaato si ay cunto u qabsato.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
