Keilhauia
Keilhauia wuxuu ahaa xayawaan badda ku nool oo u eg dolphin, kaas oo noolaa xilligii Early Cretaceous, qiyaastii 145 milyan oo sano ka hor. Wuxuu lahaa indho waaweyn iyo san dheer, wuxuuna ku dabaalan jiray badaha gacmeed ee u dhow meesha hadda loo yaqaan Norway. Wuxuu ahaa mid dhererkiisu la ekaa baabuur yar!1

Xaqiiqooyin xiiso leh
Keilhauia waxaa laga yaqaan hal laf oo kaliya, oo la helay sannadkii 2010 jasiiradda Spitsbergen.1
Magaciisa noocan ah, nui, wuxuu ka yimid magaca ururka deegaanka ee dhalinyarada Norway oo loo yaqaan Natur og Ungdom.1
Wuxuu lahaa qayb sare oo ballaaran oo ka mid ah lafta misigta iyo ischiopubis gaaban marka loo eego lafta bowdada, taas oo ka caawisa saynisyahannada inay ka soocaan ichthyosaurs-ka kale.1
Keilhauia waa ichthyosaur-ka ugu dhammaystiran ee laga yaqaan xilligii Berriasian, bilowgii xilligii Cretaceous.1
Misigtiisu waa tii ugu dhammaystirnayd ee abid laga helo xilligii Cretaceous.2
Waxay ku noolayd bad gacmeed leh sagxad ay ku yar tahay ogsijiintu, halkaas oo meelaha biyaha qabow ka soo burqadaan ay taageeri jireen xayawaanno badan oo aan lahayn laf dhabar sida ammonites iyo brachiopods.1

- Lafaha ugu horreeya ee Keilhauia waxaa helay sannadkii 2010 kooxda Spitsbergen Mesozoic Research Group ee Svalbard, Norway. Saynisyahannadu waxay u bixiyeen magaca sannadkii 2017 iyagoo u bixiyay magaca cilmi-baaraha dhulka ee Norway Baltazar Mathias Keilhau.1
- Wali waa la isku khilaafsan yahay
- Saynisyahannadu si dhab ah uma hubo sida Keilhauia ula xiriiro ichthyosaurs-ka kale sababtoo ah madaxiisa si fiican looma ilaalin, markaa booskiisa qoyska waa mid aan la hubin.1

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
