Barracudasaurus
Barracudasaurus wuxuu ahaa xamaarato badeed qadiimi ah oo ku dabaalan jirtay badaha xilligii Triassic-ga dhexe, qiyaastii 247 ilaa 237 milyan oo sano ka hor. Wuxuu u ekaa wax yar oo dolphin ah oo leh san dheer iyo ilko fiiqan, wuxuuna ahaa ugaarsade degdeg ah. In kasta oo magaciisu macnihiisu yahay 'xamaarato barracuda', ma ahayn dinosaur laakiin wuxuu ahaa ichthyosaur.21
Goorma ayuu noolaa?
Intee in le'eg ayuu u dheereeyay?
Xaqiiqooyin xiiso leh
Barracudasaurus waa mid ka mid ah mixosaurid ichthyosaurs-ka ugu da'da weyn ee la yaqaan, oo ah koox ka mid ah ichthyosaurs-ka hore.1
Madaxiisu wuxuu lahaa jeexitaan qoto dheer oo u dhexeeya lafaha jugal iyo quadratojugal, kuwaas oo kala go'naa dhinaca dibadda.1
Ilkaha dambe ee Barracudasaurus waxay ahaayeen kuwo ka ballaaran oo ka caajisan kuwa hore, taas oo ku habboon in lagu jajabiyo ugaadh adag.1
Saynisyahannadu waxay u maleynayaan in Barracudasaurus laga yaabo inuu ka soo kordhay qaybta bari ee Badweynta Tethys ee qadiimiga ah, ee ma aha galbeedka sida hore loo rumaysnaa.1
Kaliya laba fosil oo Barracudasaurus ah ayaa la helay, labaduba waxay ku jiraan Guanling Formation ee Shiinaha.2

- Barracudasaurus waxaa magacaabay 2005 Jiang iyo asxaabtiisa. Waxay barteen laba fosil oo ka yimid Guanling Formation ee Guizhou, Shiinaha: mid madax ku dhowaad dhammaystiran oo leh baal hore iyo lafaha garabka, iyo madax kale oo qayb ah. Waxay ogaadeen in fosil-yadan ay ka tirsan yihiin nooc cusub, oo ka duwan Mixosaurus.21

- Saynisyahannadu si dhab ah uma hubo inta uu weynaaday Barracudasaurus, sababtoo ah kaliya lafaha madaxa iyo baalka ayaa la helay ilaa hadda.21

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
