izinto ezinhle

Amaqiniso amnandi

I-Meraxes yayinezingalo ezazicishe zibe yingxenye yobude bethanga layo, njenge-T. rex nezinye izilwane ezinkulu ezidla inyama.1

Ukhakhayi lwayo lwalungamamitha angu-1.27 ubude, lulingana noxakhayi lwe-Acrocanthosaurus.2

Meraxes yisidumbu se-carcharodontosaurid esiphelele kakhulu esake satholakala eNingizimu Nenkabazwe.1

Uzwane lwesibili lwe-Meraxes lwalunozipho olukhulu kakhulu, olwalucishe lube lude ngokuphindwe kabili kunozipho lwesine lwaso.2

Lesi sibankwakazi saphila eminyakeni engaba ngu-100 kuya ku-90 ezigidini edlule ngesikhathi se-Cretaceous.3

Kungenzeka ukuthi i-Meraxes yayiphila iminyaka ephakathi kwengu-39 nengu-53, okuyenza ibe ngenye yama-dinosaur adla inyama aphila isikhathi eside kunawonke aziwayo.2

Amathambo ayo akhombisa ukuthi i-Meraxes yakhula yaba nkulu kakhulu ngokuthatha isikhathi eside ikhula, hhayi ngokukhula ngokushesha.2

Isithombe sika-Meraxes 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.

ubuzile

Imibuzo ebuzwa kakhulu mayelana no-Meraxes

?Yayinkulu kangakanani i-Meraxes?

Cishe amamitha ayi-9 kuya kwayi-10 ubude, futhi yayinesisindo esicishe sibe amathani ayi-4.26.2

?Ingabe i-Meraxes yayinoboya?

Imithombo ayisho lutho ngoboya be-Meraxes. Akwaziwa ngokuqinisekile, kodwa ama-theropod amakhulu amaningi afana ne-Meraxes avame ukuboniswa engenabo uboya.1 2

?Ingabe i-Meraxes yayinkulu kune-T. rex?

Cha, i-Meraxes yayincane kune-T. rex. I-T. rex yayingaba ngaphezu kwamamitha ayi-12 ubude, kanti i-Meraxes yayicishe ibe ngamamitha ayi-9 kuya kwayi-10.2

?I-Meraxes yayidla ini?

I-Meraxes yayidla inyama futhi kungenzeka ukuthi yayizingela ama-dinosaur amakhulu adla izitshalo, afana nama-sauropod anjenge-Argentinosaurus ne-Limaysaurus ayehlala endaweni eyodwa.2

?Kungani i-Meraxes yayinezingalo ezincane?

Ososayensi bacabanga ukuthi izingalo zayo zancipha njengoba ikhanda layo likhula, ngoba ugebhezi lwaluthatha umsebenzi wokubamba inyamazane. Lokhu kwenzeka emaqenjini amaningi ama-dinosaur amakhulu adla inyama, kuhlanganise ne-Meraxes ne-T. rex.1 4

?I-Meraxes yayiphila nini?

I-Meraxes yaphila eminyakeni engaba ngu-100 kuya ku-90 ezigidini edlule, ngesikhathi se-Cretaceous.2

?Ingabe i-Meraxes yayikwazi ukubhukuda?

Alukho ulwazi lokuthi i-Meraxes yayikwazi ukubhukuda yini. Njengama-theropod amakhulu amaningi, kungenzeka ukuthi yayihlala emhlabathini.2

?I-Meraxes yayikwazi ukugijima ngesivinini esingakanani?

Imithombo ayinikezi isivinini se-Meraxes. Njengomzingeli omkhulu, kungenzeka ukuthi yayingasheshi kakhulu, kodwa asikho isivinini esiqondile esaziwayo.2

Buza u-Rex ngo-Meraxes

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.

Izinsalela ezitholiwe: 1 ku-Paleobiology Database5
Ukutholakala: Amathambo okuwukuphela kwawo aziwayo e-Meraxes atholakala ngo-2012 e-Argentina. Ososayensi bayiqamba ngo-2022 ngodrako osezincwadini ze-Song of Ice and Fire.2 1
Kusaphikiswana ngakho: Ososayensi abaqiniseki ukuthi i-Meraxes yayingakanani ngobude, ngoba izindlela ezahlukene zokulinganisa zinikeza ubude obuhlukahlukene.2

Rex ulambile! I-Dino Wiki iphrojekthi kababa wendodana yakhe ethanda ama-dino, imahhala ngaphandle kwezikhangiso nezilandeleli. Abantu abadala bangaphakela u-Rex ukudla okulula ukuze basize ukuyigcina iku-inthanethi.Phakela u-Rex
