Wuxuu ahaa nooc ka mid ah ichthyosaur, xamaarato u eg dolphin oo neefsata hawo laakiin ku nool biyaha.

Goorma ayuu noolaa?

Xaqiiqooyin xiiso leh
Merriamosaurus waxaa magacaabay sannadkii 2002 saynisyahannada Maisch iyo Matzke.1
Wuxuu noolaa xilligii Spathian ee Early Triassic, qiyaastii 248 ilaa 247 milyan oo sano ka hor.1
Merriamosaurus wuxuu ahaa ichthyosaur aasaasi ah oo leh baalal dhaadheer, taas oo macnaheedu yahay inuu lahaa baalal dhaadheer wuxuuna ahaa qaraabo hore oo ka tirsan ichthyosaurs-ka horumarsan.2
Wuxuu ahaa kii ugu horumarsanaa ee ichthyosaurs-ka Lower Triassic ee la yaqaanay waqtigii sifayntiisa.2
Merriamosaurus wuxuu dhalay dhallaan nool, sida ichthyosaurs-ka kale oo badan.1

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
