Nakonanectes

Magacu wuxuu ka dhigan yahay: “Dabaasha Nakona”1

Cunay: HilibPlesiosaursCretaceous-kii dambeSi farsamo ahaan ma aha dinosaur

Nakonanectes wuxuu ahaa plesiosaur, oo ah xayawaan xamaarato ah oo badda ku nool, ee ma ahayn dinosaur. Wuxuu lahaa qoorta oo ka gaaban inta badan qaraabadiisa, taas oo ka dhigaysa nooc gaar ah oo elasmosaurid ah.1 2

Xaqiiqo xiiso leh: xayawaankan badda ku nool wuxuu dabaalanayay halka dinos-ku ay dhulka ku socdeen. Qof walba wuxuu ugu yeeraa dinos, laakiin waxay ahaayeen qayb kale oo ka mid ah xayawaanka gurguurta.

Xaqiiqooyin xiiso leh

Nakonanectes wuxuu lahaa oo kaliya 39 ilaa 42 lafood oo qoorta ah, halka qaar badan oo kale oo elasmosaurids ah ay lahaayeen in ka badan 70.1 2

Wuxuu ahaa mid ka mid ah elasmosaurids-ka waaweyn ee ugu yar ee abid la helo, isagoo dhererkiisu yahay 5.1 ilaa 5.6 m oo kaliya.1 2

Lafaha waxaa helay sanadkii 2010 ugaarsade la odhan jiray David Bradt oo ku sugan dooxada Montana.1

Nakonanectes wuxuu noolaa qiyaastii 72 ilaa 66 milyan oo sano ka hor, dhammaadkii xilligii Dinosaurs-ka.3

Madaxiisa waxaa la helay isagoo ku dhow dhammaystiran, taas oo naadir u ah lafaha elasmosaurid.1 2

Elasmosaurids-ka qoorta gaaban sida Nakonanectes waxay ka soo farcameen awoowayaal qoorta dheer oo ku noolaa qaybo kala duwan oo adduunka ah.1 2

Sawirka Nakonanectes oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Nakonanectes u ekaan karay, oo uu kombuyuutarku ka sameeyay waxa ay saynisyahannadu yaqaaniin. Waa qiyaas: xayawaanka dhabta ah waxaa laga yaabaa inuu u ekaa si ka duwan, qofna ma garanayo midabadiisa dhabta ah.

Wali waa la isku khilaafsan yahay: Saynisyahannadu weli way isku khilaafsan yihiin haddii Nakonanectes uu ka tirsan yahay kooxda Styxosaurinae ama Elasmosaurinae.3

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
