Xaqiiqooyin xiiso leh

Niobrarasaurus wuxuu ku noolaa bad gacmeed loo yaqaan Western Interior Seaway. Jirkiisu mararka qaarkood wuxuu u soo bixi jiray badda ka dib dhimashadiisa, shark-kuna waxay laga yaabaa inay lafahiisa cunaan.2

Laf-dhabartiisa waxaa helay juqraafiye Virgil Cole 1930-kii. Markii hore, saynisyahannadu waxay u maleeyeen inuu yahay ilmo sababtoo ah wuxuu ahaa mid yar.1

Fossils-kii ugu horreeyay ee dinosaur-kan waxaa loo qaatay inay yihiin qaybo qolof qoolley ah. Ka dib, khubaradu waxay ogaadeen inay ka tirsan yihiin dinosaur qolof leh.1

Niobrarasaurus wuxuu lahaa madax dheer oo cidhiidhi ah, oo aad ugu eg dinosaur-ka Pawpawsaurus marka loo eego Edmontonia oo madax ballaaran.3

Wuxuu ahaa nodosaurid, nooc ka mid ah ankylosaur oo lahaa qodxo garbihiisa iyo taargooyin lafo ah oo dhabarkiisa ah, laakiin aan lahayn dabo garaac ah.1

Magaca Niobrarasaurus macnaheedu waa 'qorratada Niobrara', ka dib qaab-dhismeedka dhagaxa ee lafahiisa laga helay.1

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

Su'aalaha ugu badan ee ku saabsan Niobrarasaurus

?Intee in le'eg ayuu ahaa Niobrarasaurus?

Saynisyahannadu waxay qiyaasayaan inuu dhererkiisu ahaa ilaa 5 m (16 ft) miisaankiisuna u dhexeeyay 227 iyo 453 kg (500 ilaa 999 lb). Hal khabiir ayaa bixiyay qiyaas ka weyn oo ah 6.5 m (21 ft) iyo 4 tan (4.4 tan oo gaaban).1

?Maxay cuni jirtay Niobrarasaurus?

Wuxuu ahaa dinosaur dhirta cuna. Wuxuu lahaa ilko iyo af dhuuban oo uu dhirta ku cuno.1 4

?Niobrarasaurus ma lahayd dabo leh guntin?

Maya, ma lahayn. Niobrarasaurus wuxuu ahaa nodosaurid, nooc ka mid ah dinosaur-ka gaashaaman oo lahaa qodxo garbihiisa iyo taargooyin lafo ah oo dhabarka kaga yaalla, laakiin dabo leh guntin ma lahayn.1

?Xagee laga helay Niobrarasaurus?

Fossilladiisa waxaa laga helay sariiraha nuuradda ee Niobrara ee galbeedka Kansas, USA, ee Degmada Gove. Lafaha waxaa laga helay dhagaxyo mar ahaan jiray qayb ka mid ah bad Cretaceous.1 4

Daahfurka: Virgil Cole wuxuu qoday lafaha ugu horreeyay 1930-kii Kansas. Maurice Mehl wuxuu u bixiyay Hierosaurus coleii 1936-kii, Kenneth Carpenter wuxuuna siiyay magaca cusub ee Niobrarasaurus 1995-kii.1
Wali waa la isku khilaafsan yahay: Saynisyahannadu ma hubo sida saxda ah ee uu u weynaa Niobrarasaurus. Khubarada kala duwan waxay bixiyaan qiyaaso aad u kala duwan, laga bilaabo qiyaastii 5 mitir ilaa 6.5 mitir.1
