Ngubani idayinaso eliyisiwula kakhulu?

I-Stegosaurus iyidayinaso eyaziwayo ebhekwa njengenye yezilwane eziyiziwula kakhulu eMhlabeni. Kodwa-ke, lesi "siwula esikhulu" sasinda eMhlabeni iminyaka engaphezu kwezigidi eziyi-100 kwaze kwaba sekuqaleni kwenkathi yeCretaceous lapho yaphela khona. I-Stegosaurus yayiyidayinaso enkulu edla uhlaza eyayiphila esikhathini seJurassic. Babehlala kakhulu emathafeni futhi babevame ukuhlala namanye amadayinaso adla uhlaza ngemihlambi emikhulu.

I-Stegosaurus yayiyi-dinosaur enkulu, cishe ingamamitha ayi-7 ubude, amamitha angu-3.5 ubude, futhi inesisindo esingamathani ayi-7. Naphezu kokuthi umzimba wayo wonke ungowendlovu yesimanje, yayinobuchopho obuncane kakhulu. Ubuchopho bukaStegosaurus babungafani kakhulu nomzimba wayo omkhulu, bungobukhulu be-walnut kuphela. Ukuhlola kubonise ukuthi ubuchopho bukaStegosaurus babubukhulu kancane kunobekati, cishe buphindwe kabili kunobuchopho bekati, futhi buncane ngisho nebhola legalofu, bunesisindo esingaphezu kwe-ounce elilodwa, ngaphansi kwama-ounces amabili ngesisindo. Ngakho-ke, isizathu sokuthi iStegosaurus ibhekwe “njengesiwula sokuqala” phakathi kwama-dinosaur kungenxa yobuchopho bayo obuncane kakhulu.

I-Stegosaurus kwakungeyona yodwa i-dinosaur enobuhlakani obuphansi, kodwa idume kakhulu phakathi kwazo zonkeama-dinosaur. Kodwa-ke, siyazi ukuthi ukuhlakanipha emhlabeni wezinto eziphilayo akuhambisani nobukhulu bomzimba. Ikakhulukazi phakathi nomlando omude wama-dinosaur, izinhlobo eziningi zazinobuchopho obuncane ngokumangalisayo. Ngakho-ke, asikwazi ukwahlulela ukuhlakanipha kwesilwane ngokusekelwe kuphela kubukhulu bomzimba waso.

Nakuba lezi zilwane ezinkulu sezishabalele isikhathi eside, i-Stegosaurus isabhekwa njenge-dinosaur eyigugu kakhulu yocwaningo. Ngokutadisha i-Stegosaurus nezinye izinsalela ze-dinosaur, ososayensi bangayiqonda kangcono indawo yemvelo yenkathi ye-dinosaur futhi baphethe ulwazi mayelana nesimo sezulu kanye nezindawo zemvelo ngaleso sikhathi. Ngesikhathi esifanayo, lezi zifundo zisisiza futhi siqonde kangcono imvelaphi kanye nokuvela kokuphila kanye nezimfihlakalo zezinto eziphilayo eMhlabeni.
