Bu muazzam et\u00e7il, son Jurassic World: Dominion filminde yer alan ikonik Giganotosaurus ile ayn\u0131 gruba, karcharodontosauridae familyas\u0131na ait.<\/p>\n\n
Meraxes gigas \u00f6rne\u011fi, bu antik y\u0131rt\u0131c\u0131lar\u0131n anatomisi ve evrimi hakk\u0131nda de\u011ferli bilgiler sa\u011flayarak, ola\u011fan\u00fcst\u00fc bir b\u00fct\u00fcnl\u00fc\u011fe sahip. \u0130yi korunmu\u015f kafatas\u0131 ve k\u0131sa \u00f6n ayaklar da dahil olmak \u00fczere neredeyse eksiksiz uzuvlar\u0131, karcharodontosauridlerin e\u015fsiz adaptasyonlar\u0131na \u0131\u015f\u0131k tutuyor.<\/p>\n\n
Meraxes gigas, \u00f6zellikle minik kollar\u0131nda olmak \u00fczere \u00fcnl\u00fc Tyrannosaurus rex ile \u00e7arp\u0131c\u0131 benzerlikler sergiliyor. Meraxes’in t\u00fcm kolu, uyluk kemi\u011finin uzunlu\u011funun yar\u0131s\u0131ndan daha k\u0131sa olup, T. rex’in yak\u0131n akrabas\u0131 olan Tarbosaurus’unkiyle kar\u015f\u0131la\u015ft\u0131r\u0131labilir bir orana sahip.<\/p>\n\n

Meraxes ve Tyrannosaurus rex gibi b\u00fcy\u00fck etobur dinozorlar\u0131n neden k\u0131sa kollar geli\u015ftirdi\u011fi sorusu, paleontologlar\u0131 uzun s\u00fcredir \u015fa\u015f\u0131rtmaktad\u0131r.

Daha b\u00fcy\u00fck kafataslar\u0131na sahip dinozorlar\u0131n daha k\u0131sa kollara sahip olma e\u011filimi vard\u0131.<\/p>\n\n

Acrocanthosaurus gibi daha \u00f6nceki karcharodontosauridlerin daha uzun \u00f6n uzuvlar\u0131 vard\u0131. Ancak, Meraxes de dahil olmak \u00fczere grubun sonraki \u00fcyeleri \u00e7ok daha k\u0131sa uzuvlar geli\u015ftirmi\u015ftir.

Meraxes ve b\u00fcy\u00fck tyrannosauruslar\u0131n k\u0131sa kollar\u0131 muhtemelen avlanma stillerine bir adaptasyon olsa da, bu uzant\u0131lar\u0131n tam i\u015flevi hala bir gizemdir.
