Tuvuze inyamaswa nini zigeze kubaho kwisi, abantu bose bazi ko ari baleine yubururu, ariko se inyamaswa nini iguruka? Tekereza ikiremwa gitangaje kandi giteye ubwoba kizerera mu gishanga hashize imyaka miriyoni 70, Pterosauria ifite uburebure bwa metero 4 zizwi ku izina rya Quetzalcatlus, ikomoka mu muryango wa Azhdarchidae. Amababa yacyo ashobora kugera kuri metero 12 z'uburebure, ndetse akagira umunwa wa metero eshatu z'uburebure. Ifite igice cya toni. Nibyo, Quetzalcatlus ninyamaswa nini iguruka izwi kwisi.
Izina ryubwoko bwaQuetzalcatlusikomoka muri Quetzalcoatl, Imana Yinzoka Yibaba mumico ya Aztec.
Quetzalcatlus rwose yariho ikomeye cyane muricyo gihe. Ahanini, umusore Tyrannosaurus Rex ntabwo yigeze arwanya na gato iyo yahuraga na Quetzalcatlus. Bafite metabolisme yihuse kandi bakeneye kurya buri gihe. Kubera ko umubiri wacyo woroshye, ukenera proteine nyinshi zingufu. Rex ntoya ya Tyrannosaurus ipima ibiro 300 irashobora gufatwa nkifunguro ryayo. Iyi Pterosauria nayo yari ifite amababa manini, bigatuma ikwiranye nintera ndende.
Ibisigazwa bya mbere bya Quetzalcatlus byavumbuwe muri parike ya Big Bend muri Texas mu 1971 na Douglas A. Lawson. Iki kigereranyo cyarimo ibaba ryigice (rigizwe nintangarugero nintoki ya kane yaguye), aho amababa afatwa ko arenga metero 10. Pterosauria niyo nyamaswa zambere zahinduye ubushobozi bukomeye bwo kuguruka nyuma yudukoko. Quetzalcatlus yari ifite sternum nini, niho imitsi yo kuguruka yari ifatanye, nini cyane kuruta imitsi yinyoni nudusimba. Ntagushidikanya rero ko ari beza cyane "aviator".
Umubare ntarengwa w’amababa ya Quetzalcatlus uracyaganirwaho, kandi wanateje impaka ku mbibi ntarengwa y’imiterere y’indege.
Hariho ibitekerezo byinshi bitandukanye muburyo bwubuzima bwa Quetzalcatlus. Kubera ururenda rurerure rw'inkondo y'umura hamwe n'urwasaya rurerure rutagira amenyo, rushobora kuba rwarahigaga amafi mu buryo busa na heron, karrion nk'igiti cyogoshe, cyangwa icyuma kigezweho cyitwa kasi.
Quetzalcatlus ifatwa nk'iyikuramo imbaraga zayo, ariko iyo mu kirere irashobora kumara umwanya munini iranyerera.
Quetzalcatlus yabayeho mugihe cyanyuma cya Cretaceous, hashize imyaka miriyoni 70 kugeza miriyoni 65.5 ishize. Barazimye hamwe na dinosaur mugikorwa cya Cretaceous-Tertiary.
