Ikhadi le-Dino No. 0021 kwangu-2 027

Acrotholus

Igama lisho ukuthi: “uphahla oluphakeme kakhulu”1

Udla: IzitshaloAmakhanda anomgogodla (ama-pachycephalosaur)Late Cretaceous

I-Acrotholus kwakuyidinaso elincane elidla izitshalo elalinesiphongo esiqinile, esinamathambo amaningi ekhanda lalo. Laphila eminyakeni engaba yizigidi ezingama-84 edlule endaweni esiyi-Canada namuhla. Lesi siphongo kungenzeka sasisebenziselwa imincintiswano yokungqubuzana ngamakhanda phakathi kwezimbangi!1 2

izinto ezinhle

Amaqiniso amnandi

I-Acrotholus iyidinosaur endala kunazo zonke eyaziwayo yohlobo lwe-pachycephalosaur eNyakatho Melika, futhi mhlawumbe nasemhlabeni wonke.2

Uphahla lwayo lwalugqinsi kakhulu, lufika ku-55 mm (cishe amayintshi angu-2) ngaphezu kobuchopho, okuyingxenye ecishe ibe yingxenye yesigamu sobude obuphelele bophahla.2

Uphahla lwalusuthuthuke ngokugcwele nakuba i-Acrotholus yayiphila ngaphambi kwamanye ama-pachycephalosaur, okukhombisa ukuthi lesi sici savela ngaphambi kokuba ososayensi bacabange.2

Igama elithi Acrotholus lisho 'uphahla oluphakeme kakhulu' ngesiGreki, libhekisela ophahleni lwayo logebhezi olugqinsi.1

Igama lohlobo elithi audeti lihlonipha u-Roy Audet, umnikazi wepulazi owavumela ososayensi ukuba bembe emhlabeni wakhe lapho kwatholakala khona ugebhezi lokuqala.1 2

I-Acrotholus yayinophahla olubushelelezi ngaphandle kwamafindo noma imigudu ebonakala kwamanye ama-pachycephalosaur, okusikisela ukuthi izinsalela ezaziwayo zivela ezilwaneni ezikhulile.2

Isithombe sika-Acrotholus 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-Acrotholus

?Wayengakanani i-Acrotholus?

IAcrotholus yayiyidinosaur encane, inesisindo samakhilogremu ayi-40 (amaphawundi ayi-88) noma ngaphansi. Ugebhezi lwayo lwalucishe lube ngama-mm ayi-55 (amayintshi ayi-2.2) ubukhulu.1 2

?I-Acrotholus yayidla ini?

I-Acrotholus yayiyidinosaur edla izitshalo, njengamanye ama-pachycephalosaur.1

?Kungani i-Acrotholus yayinophahla ekhanda?

Lolu phahla kungenzeka lwalusetshenziselwa ukushayisana ngamakhanda phakathi kwezimbangi, nakuba ososayensi besaphikisana ngokuthi zazilusebenzisa kanjani ngempela.1

?I-Acrotholus yaphila nini?

I-Acrotholus yaphila eminyakeni eyizigidi ezingu-84 kuya kwezingu-83.5 edlule, ngesikhathi se-Late Cretaceous.1

Buza u-Rex ngo-Acrotholus

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.

Umchithi wezinganekwane

Inganekwane: Abanye abantu bacabanga ukuthi i-Acrotholus yayisebenzisa uphahla lwayo ukushayisana ngamakhanda njengezimvu ezinezimpondo ezinkulu.

Iqiniso: Ososayensi abaqiniseki. Uphahla kungenzeka ukuthi lwalungolwasekubukiseni noma lokulwa, kodwa abukho ubufakazi obuqondile bokushayisana ngamakhanda ku-Acrotholus.1

Ukutholakala: Insalela yokuqala, uphahla logebhezi olucishe luphelele, yatholakala epulazini lika-Roy Audet e-Alberta, e-Canada, futhi yaqanjwa ngu-David Evans nozakwabo ngonyaka ka-2013.1 2
Kusaphikiswana ngakho: Ososayensi basaphikisana ngokuthi ngabe lolu phahla lwalusetshenziselwa ukulwa phakathi kwabesilisa noma ukuzibonisa kwabesifazane, njengoba kungekho sikhala esiphelele esitholakele.1

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
