Palintropus
Palintropus wuxuu ahaa shimbir yar oo ku noolaa dhammaadkii xilligii dinosaurs-ka. Wuu duuli karayay waxaana laga yaabaa inuu cuni jiray dhir. Fossilladiisu waa kuwo aad u dhif ah, markaa saynisyahannadu weli waxay ogaanayaan nooca shimbir ee uu ahaa.12
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Palintropus wuxuu noolaa xilligii Late Cretaceous, qiyaastii 76.5 ilaa 66 milyan oo sano ka hor.1
Kaliya dhowr lafood oo Palintropus ah ayaa la helay, oo ay ku jiraan coracoid (lafta garabka) iyo scapula (lafta garabka dambe).1
Saynisyahannadu isma waafaqsana nooca shimbir ee uu ahaa Palintropus. Qaar waxay u maleynayaan inuu ahaa qaraabo hore oo digaagga iyo turkey-ga ah (galliforms), halka kuwa kalena ay u maleynayaan inuu la xiriiray shimbiraha xeebaha sida gulls iyo auks.1
Fossilkii ugu horreeyay ee Palintropus waxaa markii hore u bixiyay magaca Cimolopteryx retusa saynisyahan Othniel Charles Marsh sannadkii 1892.1
Palintropus waxaa magaciisa hadda loo yaqaan u bixiyay Pierce Brodkorb sannadkii 1970.1
Hal daraasad oo la sameeyay sannadkii 2009 ayaa soo jeedisay in Palintropus uu ahaa shimbir hore oo la xiriirta Apsaravis, waxayna ku dartay koox cusub oo la yiraahdo Palintropiformes.1

- Fossilkii ugu horreeyay ee Palintropus, oo ahaa lafta garabka, waxaa laga helay Lance Formation ee Wyoming waxaana u bixiyay magaca Cimolopteryx retusa saynisyahan Othniel Charles Marsh sannadkii 1892. Pierce Brodkorb ayaa u bixiyay magaca Palintropus sannadkii 1970.1
- Wali waa la isku khilaafsan yahay
- Saynisyahannadu weli waxay ku doodayaan in Palintropus uu ahaa shimbir hore oo galliform ah (sida digaagga) ama shimbir ka sii horeysa oo la xiriirta shimbiraha xeebaha ama Apsaravis.1
