Dinosaure y'umupfapfa kurusha izindi ni nde?

Stegosaurus ni dinosaure izwi cyane ifatwa nk'imwe mu nyamaswa zitagira ubwenge cyane ku Isi. Ariko, iyi "dinosaure ya mbere" yabayeho ku Isi imyaka irenga miliyoni 100 kugeza mu ntangiriro za Cretaceous ubwo yazimiraga. Stegosaurus yari dinosaure nini cyane irya ibyatsi yabayeho mu gihe cya Jurassic. Yatuye cyane cyane mu bibaya kandi akenshi yabaga hamwe n'izindi dinosaure zirya ibyatsi mu matsinda manini.

Stegosaurus yari dinosaur nini cyane, ifite uburebure bwa metero 7, uburebure bwa metero 3.5, kandi ipima toni zigera kuri 7. Nubwo umubiri wayo wose wari ungana n'inzovu yo muri iki gihe, yari ifite ubwonko buto cyane. Ubwonko bwa Stegosaurus bwari bungana cyane n'umubiri wayo munini, bungana gusa n'igiti cy'inkoko. Ikizamini cyagaragaje ko ubwonko bwa Stegosaurus bwari bunini gato kuruta ubw'injangwe, bungana inshuro ebyiri n'ubwonko bw'injangwe, ndetse bunangana n'umupira wa golf, bupima garama imwe gusa, buri munsi ya garama ebyiri. Kubwibyo, impamvu Stegosaurus ifatwa nk' "umupfapfa wa mbere" muri dinosaur ni ukubera ubwonko bwayo buto cyane.

Stegosaurus ntabwo ari yo dinosaur yonyine yari ifite ubwenge buke, ariko ni yo izwi cyane kurusha izindi zosedinosaure.Ariko, tuzi ko ubwenge mu isi y’ibinyabuzima budahuye n’ingano y’umubiri. Cyane cyane mu mateka maremare ya dinosaur, amoko menshi y’inyamaswa yari afite ubwonko buto butangaje. Kubwibyo, ntidushobora gucira urubanza ubwenge bw’inyamaswa dushingiye gusa ku bunini bw’umubiri wayo.

Nubwo izi nyamaswa nini zimaze igihe kirekire zizimye, Stegosaurus iracyafatwa nk'iy'agaciro kanini mu bushakashatsi. Binyuze mu bushakashatsi bwa Stegosaurus n'izindi nyamaswa za dinosaur, abahanga mu bya siyansi bashobora gusobanukirwa neza ibidukikije byo mu gihe cya dinosaur no gusesengura amakuru yerekeye ikirere n'urusobe rw'ibinyabuzima icyo gihe. Muri icyo gihe, ubu bushakashatsi bunadufasha gusobanukirwa neza inkomoko n'impinduka z'ubuzima ndetse n'amayobera y'ibinyabuzima ku Isi.
