Megacephalosaurus

Igama lisho ukuthi: “isibankwa esinekhanda elikhulu”1

Udla: InyamaAma-PlesiosaurLate CretaceousAkuyona i-dinosaur ngempela

IMegacephalosaurus kwakuyisibankwa sasemanzini esikhulu esinentamo emfushane, esasibhukuda olwandle lwasendulo olwaluhlukanisa iNyakatho Melika kabili. Sasinamakhanda amakhulu kakhulu, okuyiwona amakhulu kunawazo wonke amanye amabankwa asolwandle atholakala kuleli zwe, futhi sisebenzisa umhlathi waso omude ukubamba izilwane ezincane.1

Iqiniso elimnandi: lesi silwane sasolwandle sasibhukuda ngenkathi ama-dinosaur ehamba emhlabathini. Wonke umuntu ubabiza ngama-dino, kodwa ayeyigatsha elihlukile lezilwane ezihuquzelayo.

Ukubhukuda, isilinganiso

Yayidleni iMegacephalosaurus?

Kungenzeka ukuthi yayidla izilwane ezincane, ngoba yayinomhlathi omude namazinyo ayelingana ngobukhulu. Amazinyo ayo ayenemigqa eyasiza ekubambeni nasekugwazeni izilwane ezishelelayo.

izinto ezinhle

Amaqiniso amnandi

I-Megacephalosaurus yayingenye yama-pliosaur okugcina, eyaphila eminyakeni engaba yizigidi ezingama-94 kuya kwezingama-93 edlule ngesikhathi sesigaba se-Turonian se-Late Cretaceous.1

Ugebhezi lwaso lwalungamamitha angu-1.75 ubude, okwenza lube ugebhezi olukhulu kunazo zonke ezaziwa eNyakatho Melika.1

Amazinyo ayenemigqa emide, emincane ebizwa ngokuthi ama-apicobasal ridges eyasiza ekubambeni nasekugwazeni izilwane ezishelelayo.1

Laliphila olwandle kanye noshaka abanjengoCretoxyrhina noSqualicorax, kanye nezinye izilwane ezihuquzelayo zasolwandle ezifana nama-mosasaurus nezimfudu zasolwandle.1

Amathambo okuqala atholakala ngo-1950 futhi ekuqaleni kwakucatshangwa ukuthi angawelinye ibankwa lasolwandle elibizwa ngokuthi iBrachauchenius lucasi.1

Kwaze kwaba ngu-2013 lapho ososayensi babona khona ukuthi amathambo ayesuka esilwaneni esisha, esihlukile, base beliqamba ngokuthi iMegacephalosaurus.1

Isithombe sika-Megacephalosaurus 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-Megacephalosaurus

?Yayinkulu kangakanani iMegacephalosaurus?

Kwakuyesinye sezilwane ezihuquzelayo zasolwandle ezinkulu kakhulu ngesikhathi saso, kulinganiselwa ukuthi sasingamamitha angu-6 kuya ku-9 ubude. Ugebhezi lwaso lodwa lwalungafinyelela kumamitha angu-1.75 ubude.1

?Yayidleni iMegacephalosaurus?

Kungenzeka ukuthi yayidla izilwane ezincane, ngoba yayinomhlathi omude namazinyo ayelingana ngobukhulu. Amazinyo ayo ayenemigqa eyasiza ekubambeni nasekugwazeni izilwane ezishelelayo.1 2

?Yaphila nini iMegacephalosaurus?

Yaphila eminyakeni engaba yizigidi ezingama-94 kuya kwezingama-93 edlule, ngesikhathi sesigaba se-Turonian se-Late Cretaceous. Yayiphakathi kwama-pliosaur okugcina.1

?Ingabe iMegacephalosaurus iyidinosaur?

Cha, akuyona idinosaur. Kuyibankwa lasolwandle, uhlobo lwesilwane esihuquzelayo sasolwandle esaphila olwandle ngesikhathi esifanayo nama-dinosaur.1

Buza u-Rex ngo-Megacephalosaurus

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.
