Quetzalcoatlus northropi, chilombo chachikulu kwambiri chowuluka chomwe sichinakhalepo, chinayendayenda mumlengalenga panthawi ya Late Cretaceous period, pafupifupi zaka 100 mpaka 66 miliyoni zapitazo. Pokhala m’banja la ma pterosaur, osati ma<em>dinosaur, cholengedwa chochititsa chidwi chimenechi chinali ndi mapiko otalikirana kuyambira mamita 37 mpaka 40, kupangitsa kukhala kochititsa mantha m’miyamba yakale.

Kufufuza kosalekeza ndi kufufuza kwa sayansi kukupitiriza kuulula zidziwitso zatsopano za moyo ndi makhalidwe a pterosaur yochititsa chidwiyi, kutithandiza kuzindikira zodabwitsa za dziko lakale ndi kusiyanasiyana kodabwitsa kwa zamoyo zomwe zinalipo pa dziko lapansili.
