Cetarthrosaurus

Magacu wuxuu ka dhigan yahay: “xamaarato dabo-wadaag ah”1

Cunay: HilibIchthyosaursCretaceous-kii horeSi farsamo ahaan ma aha dinosaur

Cetarthrosaurus wuxuu ahaa xamaarato badeed si degdeg ah u dabaasha oo ku noolaa badaha u dhow waxa hadda loo yaqaan England. Wuxuu u ekaa xoogaa sida dolphin-ka laakiin wuxuu ahaa ichthyosaur, ee dinosaur ma ahayn.1 3

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

Cetarthrosaurus wuxuu noolaa qiyaastii 100 milyan oo sano ka hor, dhammaadkii xilligii hore ee Cretaceous.3

Hal fossil oo keliya oo Cetarthrosaurus ah ayaa la helay, hal laf oo bowdo ah.2

Fossillka waxaa helay J. F. Walker meel u dhow buundada tareenka ee Ditton, waqooyi-bari ee Cambridge.2

Lafta bowdada waxay ahayd mid duugowday oo la rogrogay, sida laf xeebta ku rogmatay, ka hor intaan la aasin.2

Harry G. Seeley wuxuu magacaabay Cetarthrosaurus sanadkii 1873, isagoo ku salaynaya laftaas hal lug ah.1 3

Magaca Cetarthrosaurus wuxuu ka dhigan yahay 'xamaarato dabo-wadaag ah', isagoo tixraacaya lafaha dabadiisa.1

Sawirka Cetarthrosaurus oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Cetarthrosaurus 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 ma hubo sida saxda ah ee uu u weynaa Cetarthrosaurus, sababtoo ah hal laf oo lug ah ayaa la helay.2

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
