Quetzalcoatlus, pterozaur olarak bilinen eski u\u00e7an s\u00fcr\u00fcngen grubunun bir \u00fcyesi, yakla\u015f\u0131k 50 y\u0131l \u00f6nce ke\u015ffedildi.

Ke\u015ffine ra\u011fmen bilim insanlar\u0131, Quetzalcoatlus’un u\u00e7mak i\u00e7in muazzam v\u00fccudunu yerden nas\u0131l kald\u0131rd\u0131\u011f\u0131n\u0131 anlamakta g\u00fc\u00e7l\u00fck \u00e7ekti. \u00d6nceki hipotezler, ko\u015fup kanatlar\u0131n\u0131 \u00e7\u0131rpt\u0131\u011f\u0131n\u0131 veya kanat u\u00e7lar\u0131yla kendini itti\u011fini \u00f6ne s\u00fcr\u00fcyordu.<\/p>\n\n
Journal of Vertebrate Paleontology’de yay\u0131nlanan yak\u0131n tarihli bir \u00e7al\u0131\u015fma, Quetzalcoatlus’un u\u00e7u\u015f mekanizmas\u0131na yeni \u0131\u015f\u0131k tutuyor. Ara\u015ft\u0131rmac\u0131lar, Teksas’taki Big Bend Ulusal Park\u0131’nda kaz\u0131lan kemik koleksiyonlar\u0131n\u0131, aralar\u0131nda 20 fit kanat a\u00e7\u0131kl\u0131\u011f\u0131na sahip, daha k\u00fc\u00e7\u00fck ve yeni tan\u0131mlanm\u0131\u015f bir Quetzalcoatlus t\u00fcr\u00fcn\u00fcn kemiklerini de incelediler.<\/p>\n\n
Bir uzay m\u00fchendisi ve bir biyomekani\u011fin yard\u0131m\u0131yla ekip, Quetzalcoatlus’un \u00e7\u00f6melerek ve ard\u0131ndan kendini sekiz fit yukar\u0131 do\u011fru f\u0131rlatarak havaya f\u0131rlad\u0131\u011f\u0131n\u0131 belirledi. Bu, kanatlar\u0131n\u0131 \u00e7\u0131rpmak ve kald\u0131rma kuvveti olu\u015fturmak i\u00e7in yerden yeterli bo\u015fluk sa\u011flad\u0131.<\/p>\n\n
Havaya y\u00fckseldikten sonra Quetzalcoatlus yetenekli bir u\u00e7ucudur. Devasa g\u00f6\u011f\u00fcs kafesi, g\u00fc\u00e7l\u00fc u\u00e7u\u015f kaslar\u0131 i\u00e7in geni\u015f ba\u011flanma noktalar\u0131 sa\u011flad\u0131.

Kan\u0131tlar, Quetzalcoatlus’un yaprak d\u00f6kmeyen ormanlarda ya\u015fad\u0131\u011f\u0131n\u0131 ve su k\u00fctlelerinde avland\u0131\u011f\u0131n\u0131 g\u00f6steriyor. Daha b\u00fcy\u00fck t\u00fcrler bir bal\u0131k\u00e7\u0131l t\u00fcr\u00fcne benziyordu, s\u0131\u011f sularda dola\u015f\u0131yor ve uzun gagalar\u0131n\u0131 yenge\u00e7leri, istiridyeleri ve solucanlar\u0131 kapmak i\u00e7in kullan\u0131yordu. Daha k\u00fc\u00e7\u00fck t\u00fcrler, y\u0131l\u0131n en az bir k\u0131sm\u0131 bir araya gelmi\u015f olabilir.<\/p>\n\n
Ara\u015ft\u0131rmac\u0131lar, Quetzalcoatlus’u yaln\u0131zca fosil olarak de\u011fil, ya\u015fayan, nefes alan hayvanlar olarak g\u00f6rmenin \u00f6nemini vurguluyorlar. Onu benzer v\u00fccut tiplerine sahip modern hayvanlarla kar\u015f\u0131la\u015ft\u0131rarak bilim insanlar\u0131, davran\u0131\u015flar\u0131 ve ekolojileri hakk\u0131nda bilgi edinebilirler.<\/p>\n\n
Bu \u00e7al\u0131\u015fma, bug\u00fcne kadarki en kapsaml\u0131 Quetzalcoatlus anlay\u0131\u015f\u0131n\u0131 sa\u011flasa da, ara\u015ft\u0131rmac\u0131lar Big Bend Ulusal Park\u0131’ndaki gelecekteki kaz\u0131lar yoluyla daha fazla s\u0131r ke\u015ffetmeyi umuyorlar. Ek fosil ke\u015fifleri, bu g\u00f6rkemli yarat\u0131klar hakk\u0131ndaki anlay\u0131\u015f\u0131m\u0131z\u0131 daha da geli\u015ftirebilir.<\/p>","protected":false},"excerpt":{"rendered":"
