Magacu wuxuu ka dhigan yahay: “Wannan xamaarato, oo loogu magac daray aagga Shiinaha ee laga helay”1

Cunay: DhirtuMadax-gumburCretaceous-kii dambe

Wannanosaurus waxa uu ahaa dinosaur yar oo madax-gumbur leh oo noolaa qiyaastii 70 milyan oo sano ka hor meesha hadda loo yaqaan Shiinaha. Waxa uu lahaa madax fidsan halkii uu ka ahaan lahaa gumbur weyn, waxaana uu ahaa mid ka mid ah pachycephalosaurs-ka ugu yar ee abid la helo.1 2

Maxuu cuni jiray Wannanosaurus?

Waxaa laga yaabaa inuu ahaa mid dhirta cuna ama wax walba cuna, isagoo cunaya dhirta gaaban iyo laga yaabee cayayaanka. Ilkihiisa yaryar ee serrated-ka ah waxay u fiicnaayeen calaalinta dhirta.

Xaqiiqooyin xiiso leh

Wannanosaurus waxa uu lahaa saqaf madax oo gebi ahaanba fidsan oo leh daloollo waaweyn oo loo yaqaan supratemporal fenestrae, si ka duwan qaraabadiisa dambe ee madax-gumburka leh.2

Laftiisa bowdada waxay ahayd oo kaliya qiyaastii 8 sentimitir (3.1 inji) oo dherer ah, taas oo ka dhigaysa mid ka mid ah pachycephalosaurs-ka ugu yar.1

Lafaha madaxa ayaa isku xirmay, taas oo muujinaysa in dinosaur-kan yar uu ahaa qof weyn markii uu dhintay.1

Waxa uu lahaa daanka hoose oo dheer oo leh ilko yaryar oo leh ilkaha aragga (serrated), kuwaas oo u fiican calaalinta dhirta.2

Wannanosaurus waxa uu noolaa xilligii Late Cretaceous, qiyaastii 72 ilaa 69 milyan oo sano ka hor.1

Gacmihiisa hore waxay ahaayeen kuwo gaaban, iyadoo humerus-ku uu ahaa kaliya kala bar dhererka bowdada ama ka yar.2

Su'aalaha ugu badan ee ku saabsan Wannanosaurus

?Intee ayuu la ekaa Wannanosaurus?

Waxa uu ahaa mid aad u yar, qiyaastii 60 sentimitir (2.0 cagood) oo dherer ah. Laftiisa bowdada waxay ahayd oo kaliya qiyaastii 8 sentimitir (3.1 inji).1

?Wannanosaurus ma lahaa gumbur madaxiisa ah?

Maya, waxa uu lahaa saqaf madax fidsan oo leh daloollo waaweyn, si ka duwan pachycephalosaurs-ka dambe ee madax-gumburka leh. Taasi waa sababta saynisyahannadu u tixgeliyaan inuu yahay xubin hore oo ka mid ah kooxda.1

?Maxuu cuni jiray Wannanosaurus?

Waxaa laga yaabaa inuu ahaa mid dhirta cuna ama wax walba cuna, isagoo cunaya dhirta gaaban iyo laga yaabee cayayaanka. Ilkihiisa yaryar ee serrated-ka ah waxay u fiicnaayeen calaalinta dhirta.1

?Goormuu noolaa Wannanosaurus?

Waxa uu noolaa qiyaastii 70 milyan oo sano ka hor, xilligii Late Cretaceous (da'da Maastrichtian).1

?Xaggee laga helay Wannanosaurus?

Lafihiisa waxaa laga helay Anhui, Shiinaha, gudaha Xiaoyan Formation. Magacu wuxuu ka dhigan yahay 'Wannan xamaarato' ka dib gobolkaas.1

?Wannanosaurus ma dinosaur baa?

Haa, waa dinosaur. Waxa uu ka tirsan yahay kooxda Pachycephalosauria, kuwaas oo ah dinosaurs madax-gumbur leh, inkasta oo madaxiisu uu ahaa mid fidsan.1

Wali waa la isku khilaafsan yahay: Saynisyahannadu si dhab ah uma hubaan in Wannanosaurus uu ahaa pachycephalosaur aad u horeeyay ama inuu si dhow ula xiriiray noocyada kale ee madaxa fidsan sida Homalocephale.1 2
