Pengornis
Pengornis wuxuu ahaa shimbir ku noolaa xilligii hore ee Cretaceous, qiyaastii 120 milyan oo sano ka hor. Wuxuu ahaa mid ka mid ah shimbiraha ugu waaweyn xilligiisii, isagoo baalashiisu ay u ballaarnaayeen sida baabuur yar. Wuxuu lahaa ilko yaryar wuxuuna cuni jiray hilib.21

Xaqiiqooyin xiiso leh
Pengornis waa shimbirta ugu weyn ee enantiornithine ee laga yaqaan xilligii hore ee Cretaceous ee waqooyi-bari Shiinaha.1
Madaxiisu waa mid ka mid ah kuwa ugu wanaagsan ee la ilaaliyay dhammaan shimbiraha Mesozoic, isagoo muujinaya faahfaahin sida ilko yaryar iyo meelo ay ka muuqato duugow.2
Pengornis wuxuu lahaa laf garab oo wareegsan oo ka soo baxsanayd lafta kale, taas oo ah astaamo aan lagu arkin shimbiraha kale ee enantiornithines.2
Magaca wuxuu ka yimid 'Peng', shimbir weyn oo khuraafaad ah oo ku jirta dhaqanka Shiinaha, iyo 'ornis' oo macnaheedu yahay shimbir af-Giriig ah.1
Ilkihiisu waxay ahaayeen kuwo yaryar, oo u eg koonto, oo aan qaloocnayn, kuwaas oo la mid ah shimbirtii hore ee Archaeopteryx.2
Pengornis wuxuu lahaa dabo dheer oo leh pygostyle, laf isku darsantay oo ku taal caarada dabada taas oo ka caawin jirtay xakamaynta duulimaadka.2
Su'aalaha ugu badan ee ku saabsan Pengornis
?Intee in le'eg ayuu ahaa Pengornis?

?Pengornis ma lahaa ilko?
Haa, Pengornis wuxuu lahaa ilko yaryar oo u eg koonto kuwaas oo aan qaloocnayn, oo la mid ah shimbirtii hore ee Archaeopteryx. Wuxuu lahaa qiyaastii 13 ilig oo ku yaal daanka hoose wuxuuna u isticmaali jiray inuu ku cuno hilib.13
?Goorma ayuu noolaa Pengornis?
Pengornis wuxuu noolaa xilligii hore ee Cretaceous, qiyaastii 120 milyan oo sano ka hor.1
?Maxuu ka dhigan yahay magaca Pengornis?
Magaca Pengornis wuxuu ka yimid 'Peng', shimbir weyn oo khuraafaad ah oo ku jirta dhaqanka Shiinaha, iyo 'ornis', oo macnaheedu yahay shimbir af-Giriig ah.1

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu waxay ka doodaan in Enantiornithes iyo Ornithurae (kooxda ay ku jiraan shimbiraha casriga ah) ay yihiin kooxo kala duwan. Pengornis wuxuu leeyahay astaamo labada kooxoodba ah, taas oo ka dhigaysa kala soocidda mid adag.12
