Orienantius
Orienantius wuxuu ahaa shimbir yar oo noolaa qiyaastii 130 milyan oo sano ka hor meesha hadda loo yaqaan Shiinaha. Waxay lahayd baalal waxayna awood u lahayd inay duusho, laakiin waxay ka duwanayd shimbiraha casriga ah. Waxay ka tirsanayd koox qadiimi ah oo loo yaqaan enantiornithines, kuwaas oo lahaa qaab duulimaad oo ka duwan.21
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Orienantius waxaa lagu yaqaanaa laba lafo-beel oo ku dhow inay dhammaystiran yihiin kuwaas oo weli leh baalal iyo xitaa unugyo jilicsan sida maqaarka baalka oo la ilaaliyay.12
Waxay lahayd cabbirka shimbirta Eurasian Skylark ee casriga ah, taas oo ah shimbir yar oo heesta.1
Orienantius waxay awood u lahayd inay si xirfad leh u duusho waxayna isticmaali jirtay qaab duulimaad oo baalasha garaaca ah, sida qaar ka mid ah shimbiraha maanta.2
Muunadda ugu weyn (holotype) si buuxda uma korin markii ay dhimatay, qaar ka mid ah lafaheeda weli iskumay biirin.1
Magaceedu wuxuu ka yimid ereyo Laatiin iyo Giriig ah oo macnahoodu yahay 'bari' iyo 'ka soo horjeeda', taas oo tixraacaysa helitaankeeda Bariga Aasiya iyo kooxdeeda Enantiornithes.1
Orienantius waxay noolayd xilligii hore ee Cretaceous, taas oo ka dhigaysa mid ka mid ah shimbiraha ugu da'da weyn ee enantiornithine ee la yaqaan.2

- Orienantius waxaa magacaabay Di Liu iyo asxaabtiisa sanadkii 2019, iyagoo ku saleynaya laba fossil oo laga helay Huajiying Formation ee Hebei, Shiinaha. Magaca nooca ritteri wuxuu sharaf u yahay saynisyahanka Jarmalka ah ee Johann Wilhelm Ritter.12
- Wali waa la isku khilaafsan yahay
- Saynisyahannadu weli way ka doodayaan sida saxda ah ee Orienantius iyo shimbiraha kale ee hore ee enantiornithines ay u horumariyeen awooddooda duulimaad, maadaama ay muujinayaan astaamo u gaar ah shimbiraha hore iyo kuwa casriga ahba.2

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
