Tichitaura nezvemhuka huru kwazvo yakambovapo pasi rose, munhu wese anoziva kuti ihove yebhuruu, asi zvakadini nemhuka huru kwazvo inobhururuka? Fungidzira chisikwa chinoshamisa uye chinotyisa chinofamba-famba mudhamu makore angangoita mamiriyoni makumi manomwe apfuura, Pterosauria ine urefu hwemamita mana inozivikanwa seQuetzalcatlus, iyo iri yeMhuri yeAzhdarchidae. Mapapiro ayo anogona kusvika mamita gumi nemaviri pakureba, uye ine muromo wakareba mamita matatu. Inorema hafu yetani. Ehe, Quetzalcatlus ndiyo mhuka huru kwazvo inobhururuka inozivikanwa pasi rose.
Zita rerudzi rweQuetzalcatlusinobva kuna Quetzalcoatl, Mwari weNyoka ine Minhenga mutsika dzeAztec.
Quetzalcatlus yaive hupenyu hwakasimba kwazvo panguva iyoyo. Chaizvoizvo, Tyrannosaurus Rex diki yakanga isina kana simba payakasangana neQuetzalcatlus. Iine metabolism inokurumidza uye inoda kudya nguva dzose. Nekuti muviri wayo wakarongeka, inoda mapuroteni akawanda kuti ive nesimba. Tyrannosaurus rex diki inorema pasi pemapaundi mazana matatu inogona kuonekwa sechikafu chayo. Pterosauria iyi yaivewo nemapapiro makuru, izvo zvakaita kuti ikodzere kubhururuka kure.
Chisaririra chekutanga cheQuetzalcatlus chakawanikwa muBig Bend National Park muTexas muna 1971 naDouglas A. Lawson. Chifananidzo ichi chaisanganisira bapiro diki (raive negumbo repamberi rine munwe wechina wakatambanudzwa), iro mapapiro anofungidzirwa kuti anopfuura mamita gumi. Pterosauria ndiyo mhuka dzekutanga kugadzira kugona kwakasimba kwekubhururuka dzichitevera zvipembenene. Quetzalcatlus yaive nesternum hombe, ndipo pakabatanidzwa tsandanyama dzekubhururuka, dzakakura kupfuura tsandanyama dzeshiri nemapopoma. Saka hapana mubvunzo kuti i“aviationer” vakanaka kwazvo.
Muganho wepamusoro wemapapiro eQuetzalcatlus uchiri kukurukurwa, uye zvakakonzerawo gakava pamusoro pemuganho wepamusoro wechimiro chekubhururuka kwemhuka.
Kune mafungiro akasiyana-siyana pamusoro pemararamiro eQuetzalcatlus. Nekuda kwemapfupa ayo marefu emumuromo uye shaya refu dzisina mazino, inogona kunge yakavhima hove nenzira yakaita seyeheron, yakaora seyebald stork, kana kuti shiri yemazuva ano ine muromo wechikero.
Quetzalcatlus inofungidzirwa kuti inobhururuka nesimba rayo, asi kana yangosvika mudenga inogona kupedza nguva yakawanda ichibhururuka.
Quetzalcatlus akararama munguva yekupedzisira yeCretaceous, makore angangoita mamiriyoni makumi manomwe apfuura kusvika makore mamiriyoni makumi matanhatu nemashanu nemashanu apfuura. Akatsakatika pamwe chete nemadinosaur muchiitiko chekutsakatika kweCretaceous-Tertiary.
