Ngubani idayinaso eyisidenge kakhulu?

I-Stegosaurus yidinosaur eyaziwayo ethathwa njengenye yezilwanyana eziziziyatha eMhlabeni. Nangona kunjalo, esi "sisidenge sokuqala" sasinda eMhlabeni iminyaka engaphezu kwe-100 yezigidi de kwaba lixesha leCretaceous xa yaphela. I-Stegosaurus yayiyidinosaur enkulu edla utyani eyayiphila kwixesha leJurassic. Babehlala kakhulu emathafeni kwaye babehlala nezinye iidinosaur ezidla utyani kwimihlambi emikhulu.

I-Stegosaurus yayiyidinosaur enkulu, malunga neemitha ezisi-7 ubude, iimitha ezi-3.5 ubude, kwaye inobunzima obumalunga neetoni ezisi-7. Nangona umzimba wayo wonke wawulingana nendlovu yanamhlanje, yayinobuchopho obuncinci kuphela. Ingqondo ye-Stegosaurus yayingalingani kakhulu nomzimba wayo omkhulu, kuphela ubukhulu be-walnut. Uvavanyo lubonise ukuba ingqondo ye-Stegosaurus yayinkulu kancinci kuneyekati, malunga nobukhulu obuphindwe kabini kunobuchopho bekati, kwaye incinci kunebhola yegalufa, inobunzima obungaphezulu kwe-ounce enye, ngaphantsi kwee-ounces ezimbini ubunzima. Ke ngoko, isizathu sokuba i-Stegosaurus ithathwe njenge "sisidenge esiphambili" phakathi kwee-dinosaur kungenxa yobuchopho bayo obuncinci kakhulu.

IStegosaurus yayingeyodwa idinosaur ekrelekrele kancinci, kodwa yeyona idumileyo phakathi kwazo zonkeiidayinasoNangona kunjalo, siyazi ukuba ubukrelekrele kwihlabathi lebhayoloji abulingani nobukhulu bomzimba. Ingakumbi ngexesha lembali ende yeedayinaso, uninzi lweentlobo zezilwanyana lwaluneengqondo ezincinci ngendlela emangalisayo. Ke ngoko, asinakugweba ubukrelekrele besilwanyana ngokusekelwe kubukhulu bomzimba waso kuphela.

Nangona ezi zilwanyana zinkulu bezisele ziphelile ixesha elide, iStegosaurus isathathwa njengedinosaur exabisekileyo kakhulu kuphando. Ngokufunda iStegosaurus kunye nezinye iifosili zedinosaur, izazinzulu zinokuyiqonda ngcono imeko-bume yendalo yexesha ledinosaur kwaye zifumane ulwazi malunga nemozulu kunye ne-ecosystem ngelo xesha. Kwangaxeshanye, ezi zifundo zisinceda siqonde ngcono imvelaphi kunye nokuguquka kobomi kunye neemfihlakalo zezinto eziphilayo eMhlabeni.
