Iintsiba ezigciniweyo ezigcinwe emva kweminyaka eyi-118 yezigidi zafunyanwa e-Australia, zikhokelela kwiingcali zokucinga ukuba iidinosaurs ezinamaphiko ezidlayo zazihlala eMhlabeni Phantsi.
Indawo yeSizwe ixelwe NgoMvulo, ukuba iintsiba kungenzeka ukuba zezedinosaurs ezincinci ukubanceda ukuba babambelele kwimozulu ebanda kakhulu kwisangqa se-polar esemazantsi kwixesha lokuqala laseCretaceous. Iziphumo ziya kupapashwa kuphando oluzayo kwiphephancwadi Gondwana Research.
Iipaleontologists zafumanisa iintsiba kwindawo ebizwa ngokuba yiKoonwarra, malunga neekhilomitha ezingama-90 kumazantsi mpuma eMelbourne. Iintsiba kungenzeka ukuba zalahleka ngexesha lokunyibilika okanye ukulungiswa, ngokwengxelo, emva koko zahamba zaya kumphezulu wechibi lakudala, zatshona ezantsi kwaye zagcinwa eludakeni.
Amathambo eDinosaur kunye namathambo abuthathaka eentaka zakuqala afunyenwe kwiindawo eziphakamileyo zamandulo ngaphambili. Okwangoku, ukuza kuthi ga ngoku, akusekho nto ibhaliweyo ethe yafunyanwa ukubonisa ukuba iidinosaurs zisebenzisa iintsiba ukuze ziphile kwiindawo ezihlala abantu kakhulu, uGqirha Benjamin Kear waseUppsala University eSweden, umbhali ophambili kolu phando, yatsho kwingxelo emalunga nesifundo . Ezi ntsiba ze-fossil zase-Australia zibaluleke kakhulu ke ngoko kuba zazivela kwiidinosaurs kunye neentaka ezincinci ezazihlala kwindawo ebandayo kakhulu eneenyanga zobumnyama be-polar minyaka le.

Ngokwengxelo, iAustralia yayikade isiya emazantsi kwaye yayiqhagamshelene neAntarctica, inyanzela iidinosaurs ezihlala apho ukuba zijongane neenyanga zobumnyama kunye namaqondo obushushu aqandayo ngexesha lobusika.
Isiza ngokwaso safunyanwa xa indlela inqumle intaba kwii-1960s, ngokuka Indawo yeSizwe , kwaye izazinzulu bezisenza ukumba apho ngaphezulu kweminyaka engama-60 edlulileyo.
Xa ucinga ngeentaka eAntarctica, oonombombiya ngabokuqala ukufika engqondweni. Kwaye ngelixa ezi dinosaurs zazingakhange zibukeke ngathi ziiphengwini zanamhlanje, zabonakala ngathi zabelana ngokufana: uphononongo lufumanise ukuba uninzi lweentsiba alunakuba nako ukuqhubeka nokubhabha, lusenza ukuba kungenzeka ukuba ziidinosaurs ezidla umhlaba, ngokwe Indawo yeSizwe . Kwaye kwafunyanwa umkhondo weefossilised iipakethi zombala obizwa ngokuba yimelanosomes kwiintsiba, okuthetha ukuba zazinokuba mnyama, zimpunga, zimdaka, okanye zinemigca emnyama.

Oososayensi baya kuqhubeka nokukhangela inkqubela phambili kwiziphumo zabo, benethemba lokufunda okungakumbi malunga nezidalwa zangaphambili ezazihlala emhlabeni ngaphambi kwethu.
Ukufumana amathambo edinosaur enentsiba apha e-Australia kungamangalisa, utshilo uStephen Poropat, ugqirha wezinto zakudala kwiYunivesithi yaseSwinburne eMelbourne. Indawo yeSizwe . Kwaye ngokokwazi kwethu, iKoonwarra yindawo apho kunokwenzeka ukuba ivele khona.
