Majungasaurus

Igama lisho ukuthi: “Isibankwa saseMahajanga”1

Udla: InyamaAma-dino adla inyamaLate Cretaceous

IMajungasaurus kwakuyisibankwa esidla inyama esasihlala esiqhingini saseMadagascar ngasekupheleni kwesikhathi samaDinosaur. Kwakuyisilwane esizingelayo esiphambili endaweni yakubo, futhi ososayensi baze bathola nobufakazi bokuthi kwesinye isikhathi kwakudla ezinye izilwane zohlobo lweMajungasaurus!1 2

Ingabe iMajungasaurus yayidla ezinye izilwane?

Yebo, yayizingela kakhulu izilwane ezinezintamo ezinde ezifana ne-Rapetosaurus. Yayidla nezinye izilwane zohlobo lweMajungasaurus, okuyenza ibe ngesinye sezilwane ezimbalwa ezaziwa ngokudla uhlobo lwazo.

Amaqiniso amnandi

I-Majungasaurus yaphila eminyakeni ecishe ibe yizigidi ezingama-70 kuya kwezingama-66 edlule, ngasekupheleni kwesikhathi se-Cretaceous. Yayingenye yezidinaso zokugcina ezingezona izinyoni ngaphambi kokunyamalala okukhulu.1

Lesi silwane sasinekhanda eliwugqinsi nelinamagquma elinophondo olulodwa oluyindilinga phezulu ekhanda. Uphondo lwalwenziwe ngamathambo futhi kungenzeka lwalusetshenziselwa ukushayisana ngamakhanda noma ukuzibonisa.1 2

IMajungasaurus yayingamamitha ayi-6 kuya kwayi-7 ubude, okulingana nebhesi elikhulu lesikole. Yayiyisilwane esidla inyama esinosayizi omaphakathi, ingekho ngobukhulu njenge-T. rex kodwa yayiseyisilwane esizingelayo esinolaka.2

Izinsalela zibonisa ukuthi iMajungasaurus kwesinye isikhathi yayidla ezinye izilwane zohlobo lwayo. Izimpawu zamazinyo emathanjeni ayo zifana ncamashi namazinyo ayo, okuyenza ibe ngesinye sezilwane ezimbalwa ezaziwa ngokudla uhlobo lwazo.2

Yayihlala nezinye izilwane eziningi, kuhlanganise nesilwane esinentamo ende i-Rapetosaurus, isilwane esincane esidla inyama i-Masiakasaurus, nezilwane ezinkulu ezifana nengwenya.1

Izinsalela zokuqala zeMajungasaurus zatholakala ngo-1895 ngabahloli bamazwe baseFrance. Ekuqaleni, ososayensi babecabanga ukuthi iwuhlobo lwe-Megalosaurus, kanti kamuva yaze yabizwa nangokuthi iMajungatholus.1 2

IMajungasaurus ingenye yezilwane ezidla inyama ezaziwa kakhulu emazwenikazi aseNingizimu. Kutholakale amakhanda namathambo amaningi aphelele, ngakho ososayensi bazi okuningi ngayo.2

Isithombe sika-Majungasaurus 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-Majungasaurus

?Yayinkulu kangakanani iMajungasaurus?

I-Majungasaurus yayingamamitha ayi-6 kuya kwayi-7 ubude (20 kuya kuma-23 feet) futhi inesisindo esingaba amakhilogremu angama-750 kuya kwangama-1,100 (1,650 kuya kuma-2,430 pounds). Ezinye izilwane ezinkulu kakhulu kungenzeka zafika ngaphezu kwamamitha ayi-8 (26 feet).1

?Ingabe iMajungasaurus yayidla ezinye izilwane?

?Iphila nini iMajungasaurus?

?Ingabe iMajungasaurus yayinophondo?

Yebo, yayinophondo olulodwa oluyindilinga phezulu ekhanda, olwenziwe ngamathambo. Ososayensi bacabanga ukuthi kungenzeka lwalusetshenziselwa ukushayisana ngamakhanda noma ukuzibonisa.1

?Ingabe iMajungasaurus yayinkulu kune-T. rex?

Cha, iMajungasaurus yayincane kakhulu. I-T. rex yayingamamitha ayi-12 ubude futhi inesisindo esingaphezu kwamathani ayi-8, kanti iMajungasaurus yayingamamitha ayi-6 kuya kwayi-7 kuphela ubude futhi inesisindo esingaba ithani elilodwa.1

?Itholakale kuphi iMajungasaurus?

Zonke izinsalela zeMajungasaurus zitholakale enyakatho-ntshonalanga yeMadagascar, endaweni yaseMaevarano Formation. Izinsalela zokuqala zatholakala eceleni komfula iBetsiboka ngo-1896.1

?Ingabe iMajungasaurus yayinoboya?

Akekho owazi ngokuqinisekile. Azikho izimpawu zoboya ezitholakale nezinsalela zeMajungasaurus, futhi yayiyilungu leqembu lezilwane (abelisaurids) ezingaziwa ukuthi zazino boya.1

?Ingabe iMajungasaurus iyisilwane esiyidinosaur?

Yebo, iMajungasaurus iyidinosaur. Iwuhlobo lwe-theropod, okusho ukuthi yayiyisilwane esidla inyama, esihamba ngezinyawo ezimbili.1

Umchithi wezinganekwane

Inganekwane: Abanye abantu bacabanga ukuthi iMajungasaurus yayiwuhlobo lwe-tyrannosaur efana ne-T. rex.

Iqiniso: IMajungasaurus empeleni yayiyisilwane sohlobo lwe-abelisaurid, iqembu elihlukile lezilwane ezidla inyama ezazihlala kakhulu emazwenikazi aseNingizimu. Yayinekhanda elifushane nelijulile kanye nezingalo ezincane kakhulu, kodwa yayingahlobene kakhulu ne-T. rex.1 2

Ochwepheshe bama-dino

Igama lesayensi: Majungasaurus
Iqanjwe ngu: Lavocat 19555
Iqembu: Ama-dino adla inyama
Umndeni / i-clade: Abelisauridae5
Ukuhlukaniswa: Theropoda > Ceratosauria > Abelisauridae5
Inkathi yamadwala: 72 kuya ku-66 wezigidi zeminyaka (Maastrichtian)5
Izakhiwo zamatshe: Maevarano5
Amazwe: Madagascar5
Izinsalela ezitholiwe: 25 ku-Paleobiology Database5
Eyaziwa nangokuthi: Majungatholus (amagama amadala manje abalwa njengesilwane esisodwa)5
Ukutholakala: Izinsalela zokuqala zeMajungasaurus zatholakala ngo-1895 eMadagascar ngabahloli bamazwe baseFrance. Yabizwa ngokuthi iMajungasaurus ngusosayensi wezinsalela waseFrance uRené Lavocat ngo-1955, eqanjwe ngesifunda saseMahajanga lapho yatholakala khona.1 5
Kusaphikiswana ngakho: Ososayensi abaqiniseki ukuthi uphondo olulodwa ekhanda leMajungasaurus lwalusetshenziselwani. Kungenzeka ukuthi lwalusetshenziselwa ukulwa nezimbangi, ukuheha abalingani, noma kokubili.1
