Xiphodracon
Xiphodracon wuxuu ahaa xamaarato badeed ku dabaalan jirtay badaha xilligii Jurassic. Wuxuu lahaa san aad u dheer oo dhuuban sida seefta iyo indho waaweyn. Waa mid ka mid ah ichthyosaurs-ka ugu dhameystiran ee abid laga helo xilligiisa.1

Xaqiiqooyin xiiso leh
Xiphodracon wuxuu lahaa madax dhererkiisu yahay 64.2 cm, oo leh san aad u dhuuban oo fiiqan.1
Indhihiisu waxay ahaayeen kuwo waaweyn oo ku dhowaad ay ka buuxaan giraan ka kooban qiyaastii 17 taarikada lafaha ah oo loo yaqaan scleral ring.1
Fossil-ka kaliya ee la yaqaan ee Xiphodracon wuxuu muujinayaa calaamadaha dhaawacyada: laf-dhabarta oo jabtay, ilkaha oo xun, iyo dhaawaca lafaha oo ka yimid dhibaatooyinka quusitaanka.1
Qofkan shakhsiga ah wuxuu u badan yahay inuu dhintay ka dib markii uu madaxa ka qaniinay ugaarsade ka weyn, laga yaabee Temnodontosaurus dhererkiisu yahay 9 mitir.1
Xiphodracon waa lafaha ichthyosaur ee ugu dhameystiran ee abid laga helo xilligii Pliensbachian, qiyaastii 185 milyan oo sano ka hor.1
Wuxuu si dhow ula xiriiraa Hauffiopteryx, waxayna wada sameeyaan koox la yiraahdo Hauffiopterygia.3

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu weli waxay ku doodayaan sida saxda ah ee Xiphodracon ula xiriirto ichthyosaurs-ka kale, iyo haddii ay matalayso koox cusub oo soo baxday xilligii Pliensbachian.3
