Athabascasaurus

Magacu wuxuu ka dhigan yahay: “Athabasca xamaarato”1

Cunay: HilibIchthyosaursCretaceous-kii horeSi farsamo ahaan ma aha dinosaur

Athabascasaurus wuxuu ahaa ichthyosaur dhex-dhexaad ah, oo ah xamaarato badeed ku dabaalan jirtay badaha qadiimiga ah ee Alberta, Kanada, qiyaastii 112 milyan oo sano ka hor. Wuxuu u ekaa wax yar oo dolphin ah oo leh san dheer iyo indho waaweyn, wuxuuna ahaa ugaarsade hilib-cun ah oo dheereeya.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

Athabascasaurus wuxuu lahaa 42 laf-dhabar oo ka horreeya miskaha, taas oo ah tiro aad u yar oo loogu talagalay ophthalmosaurid ichthyosaur.1

Magaciisu wuxuu ka yimid Wabiga Athabasca, kaas oo mara aagga saliidda ee laga helay fosil-ka.1

Fosil-ka kaliya ee la yaqaan ee Athabascasaurus waxaa la helay sanadkii 2000 oo ku yaal macdan qodista saliidda, waxaana hadda lagu hayaa Matxafka Royal Tyrrell ee Alberta.1

Ichthyosaur-kan wuxuu lahaa muuqaal gaar ah oo ku yaal madaxiisa: qayb saddex xagal ah oo ku taal lafta postfrontal taas oo ku fidsan lafta postorbital.1

Athabascasaurus wuxuu noolaa xilligii Early Cretaceous, qiyaastii 112 ilaa 109 milyan oo sano ka hor, markii Alberta ay daboolnayd bad diirran oo gacmeed ah.1 2

Sawirka Athabascasaurus oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Athabascasaurus 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.
