Acristavus

Igama lisho ukuthi: “umkhulu ongenaphondo”1

Udla: IzitshaloAma-hadrosaurLate Cretaceous

I-Acristavus yayiyidayinaso enomlomo wedada eyayiphila eminyakeni eyizigidi ezingaba ngu-80 edlule. Yayingenalo iqhubu ekhanda layo, okuyinto engavamile emndenini wayo. Lesi sidla zitshalo sasihamba ngezinyawo ezimbili futhi sasiyakwazi nokuhamba ngazo zonke ezine.1 2

izinto ezinhle

Amaqiniso amnandi

I-Acristavus isho 'umkhulu ongenaphondo' ngoba ingelinye lama-dinosaur amadala aziwayo anomlomo onjengowadada angenalo uphondo ekhanda.1

Amathambo ayo atholakala e-Two Medicine Formation e-Montana nase-Wahweap Formation e-Utah.5

I-Acristavus yayiphila ngesikhathi sesiteji se-Campanian se-Late Cretaceous, eminyakeni eyizigidi ezingaba ngu-83 kuya ku-72 edlule.1

Yayiyingxenye yeqembu elibizwa ngokuthi ama-Brachylophosaurini, elihlanganisa amanye ama-dinosaur anomlomo onjengowadada afana ne-Brachylophosaurus.1

Isibonelo esiyinhloko, esibizwa ngokuthi i-MOR 1155, siwuhlaka lwamathambo oluyingxenye olwasiza ososayensi ukuba bahlonze lolu hlobo.5

I-Acristavus yayiyisilwane esidla izitshalo esihlala phansi futhi esazalela amaqanda, njengabo bonke abanye o-dinosaur abanomlomo onjengowadada.2

Isithombe sika-Acristavus esenziwe nge-AI sokuthi kungenzeka ukuthi wayebukeka kanjani, senziwe yikhompyutha ngokusekelwe kulokho okwaziwa ososayensi. Lokhu kuwukuqagela: isilwane sangempela kungenzeka ukuthi sasibukeka ngokuhlukile, futhi akekho owazi imibala yaso yangempela.

Imibuzo ebuzwa kakhulu mayelana no-Acristavus

?Yayinkulu kangakanani i-Acristavus?

Ososayensi abakashicileli ukulinganisa okugcwele kosayizi wayo, kodwa njenge-hadrosaur yayicishe ibe ngamamitha ayi-8 kuya kwayi-9 ubude, icishe ilingane nebhesi lesikole.3 5

?Ingabe i-Acristavus yayinophondo?

Cha. I-Acristavus ikhethekile ngoba yayingenalo uphondo noma imihlobiso ekhanda layo, ngokungafani neningi lamanye ama-dinosaur anomlomo onjengowadada.3 4

?I-Acristavus yayidla ini?

I-Acristavus yayiyisilwane esidla izitshalo. Yayidla izinkunzane, amaqabunga nezinye izitshalo ezazikhula endaweni yayo enomswakama.5 3

?I-Acristavus yaphila nini?

I-Acristavus yayiphila eminyakeni eyizigidi ezingaba ngu-79 kuya ku-81 edlule, ngesikhathi sesiteji se-Campanian se-Late Cretaceous.3 5

Buza u-Rex ngo-Acristavus

Rex uphendula imibuzo mayelana naleli khasi kuphela. Imibuzo engu-10 ngenyanga.

Rex uyi-AI futhi angenza amaphutha. Usebenza kumaseva ase-EU futhi imibuzo ayilokothi ilondolozwe. Ungalokothi uthayiphe igama lakho noma ezinye izinto zakho.
