Gengasaurus
Gengasaurus wuxuu ahaa xayawaan badeed si degdeg ah u dabaasha oo ku noolaa badaha diirran ee Jurassic. Wuxuu u ekaa wax yar sida dolphin-ka laakiin dhab ahaantii wuxuu ahaa ichthyosaur, ee ma ahayn dinosaur. Wuxuu lahaa san dheer oo ay ka buuxaan ilko fiiqan si uu u qabto kalluunka iyo squid-ka.32
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Gengasaurus waxaa loo bixiyay magac 2017, laakiin lafaha waxaa dhab ahaantii la helay 1976. Waxaa loo yaqaanay 'Genga ichthyosaur' sanado badan ka hor inta uusan helin magaciisa rasmiga ah.1
Laba ilig oo shark ah oo ka tirsan amarka Hexanchiformes ayaa laga helay lafaha Gengasaurus. Saynisyahannadu waxay u maleynayaan in shark-yadu laga yaabo inay cuni jireen ichthyosaur-ka dhintay.2
Gengasaurus wuxuu ka tirsan yahay koox loo yaqaan Ophthalmosauridae, taas oo macnaheedu yahay 'qorratada indhaha'. Ichthyosaurs-kan waxay lahaayeen indho aad u waaweyn si ay ugu arkaan biyaha mugdiga ah.32
Lafaha waxaa laga helay Calcari ad aptici e Saccocoma Formation ee Talyaaniga, taas oo mar ahaan jirtay qayb ka mid ah Badweynta Tethys ee diirran.32
Gengasaurus wuxuu ku noolaa qiyaastii 152 milyan oo sano ka hor, intii lagu jiray xilligii Late Jurassic.1

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu si dhab ah uma hubo meesha uu Gengasaurus ka galo geedka qoyska ichthyosaur. Wuxuu la wadaagaa astaamo labada qaybood ee woqooyi iyo koonfur ee ophthalmosaurids, taas oo soo jeedinaysa inuu noqon karo xiriir ka dhexeeya kooxo kala duwan.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
