Geni\u015f ve kurak Gobi \u00c7\u00f6l\u00fc’nde, paleontologlar bilim camias\u0131n\u0131n ilgisini \u00e7eken k\u00fc\u00e7\u00fck bir dinozorun fosille\u015fmi\u015f kal\u0131nt\u0131lar\u0131n\u0131 ortaya \u00e7\u0131kard\u0131lar. Ad\u0131 Albinykus baatar olan bu yarat\u0131k, ke\u015ffedilen en k\u00fc\u00e7\u00fck dinozorlardan biri olarak kabul ediliyor.<\/p>\n\n
Albinykus, alvarezsauridler olarak bilinen tuhaf bir dinozor grubuna aittir. Bu gizemli yarat\u0131klar k\u00fc\u00e7\u00fck boyutlar\u0131, benzersiz anatomileri ve muhtemelen kar\u0131nca yedikleri al\u0131\u015fkanl\u0131klar\u0131yla karakterize edilirler. Khugenetslavkant fosil alan\u0131nda bulunan Albinykus’un kal\u0131nt\u0131lar\u0131, esas olarak kumta\u015f\u0131 bir blo\u011fa g\u00f6m\u00fclm\u00fc\u015f birka\u00e7 bacak kemi\u011finden olu\u015fmaktad\u0131r.<\/p>\n\n
S\u0131n\u0131rl\u0131 korunma durumuna ra\u011fmen paleontologlar, Albinykus’un \u00f6l\u00fcm an\u0131ndaki duru\u015funu yeniden olu\u015fturabildiler. Bacaklar v\u00fccudun alt\u0131na k\u0131vr\u0131lm\u0131\u015ft\u0131r ve dinozorun bir ku\u015f gibi oturuyormu\u015f gibi bir izlenim vermektedir. Bu al\u0131\u015f\u0131lmad\u0131k pozisyon, Albinykus’un oturur pozisyondayken \u00f6ld\u00fcr\u00fclm\u00fc\u015f ve korunmu\u015f olabilece\u011fini d\u00fc\u015f\u00fcnd\u00fcrmektedir.<\/p>\n\n
Albinykus baatar’\u0131n 1,5 ila 2 pound a\u011f\u0131rl\u0131\u011f\u0131nda oldu\u011fu tahmin ediliyor, bu da onu yakla\u015f\u0131k 77 ila 88 pound a\u011f\u0131rl\u0131\u011f\u0131nda oldu\u011fu tahmin edilen \u00f6nceki akrabas\u0131 Patagonykus’tan \u00f6nemli \u00f6l\u00e7\u00fcde daha k\u00fc\u00e7\u00fck yapmaktad\u0131r. Zamana ba\u011fl\u0131 olarak boyutlarda g\u00f6r\u00fclen bu ani azalma, alvarezsauridlerin ait oldu\u011fu daha b\u00fcy\u00fck grup olan coelurosaurlar aras\u0131nda nadir g\u00f6r\u00fclen bir durumdur. Bu kadar \u00f6nemli bir boyut azalmas\u0131n\u0131n bilinen tek ba\u015fka \u00f6rne\u011fi, ilk ku\u015flar\u0131n evrimi s\u0131ras\u0131nda meydana gelmi\u015ftir.<\/p>\n\n
Albinykus’un ke\u015ffi, Alvarezsauroidea i\u00e7indeki evrimsel \u00f6r\u00fcnt\u00fclere \u0131\u015f\u0131k tutmu\u015ftur. Albinykus’un da eklenmesiyle, Gobi \u00c7\u00f6l\u00fc’ndeki her b\u00fcy\u00fck Kretase b\u00f6lgesi en az bir alvarezsaurid fosili vermi\u015ftir ve bu da bu dinozorlar\u0131n tarih \u00f6ncesi Asya’daki zengin ve \u00e7e\u015fitli ge\u00e7mi\u015fini g\u00f6stermektedir.<\/p>\n\n
Albinykus’un ya\u015fam tarz\u0131 ve beslenme al\u0131\u015fkanl\u0131klar\u0131 hala bir gizem olarak kalmaktad\u0131r. Genel olarak alvarezsauridler, pangolinler ve aardvarklar gibi kar\u0131nca yiyen memelilerin yap\u0131s\u0131na benzer \u015fekilde, \u00e7ok say\u0131da k\u00fc\u00e7\u00fck di\u015fe ve b\u00fcy\u00fck bir pen\u00e7eyle donat\u0131lm\u0131\u015f g\u00fc\u00e7l\u00fc kollara sahiptirler. Bu durum, alvarezsauridlerin kar\u0131nca yiyen dinozorlar oldu\u011fu y\u00f6n\u00fcndeki yayg\u0131n hipoteze yol a\u00e7m\u0131\u015ft\u0131r.<\/p>\n\n
Ancak bu hipotezi destekleyecek kesin kan\u0131tlar hen\u00fcz bulunamam\u0131\u015ft\u0131r. Hi\u00e7bir alvarezsaurid fosilinde sindirim sistemi i\u00e7eri\u011fi, alvarezsauridlerin beslendi\u011fini g\u00f6steren hasarl\u0131 fosille\u015fmi\u015f termit yuvalar\u0131 veya kar\u0131nca kal\u0131nt\u0131lar\u0131 i\u00e7eren d\u0131\u015fk\u0131lar (fosille\u015fmi\u015f d\u0131\u015fk\u0131) ke\u015ffedilmemi\u015ftir. Kar\u0131nca yiyen dinozor hipotezi hala en makul a\u00e7\u0131klama olsa da bilim insanlar\u0131 bunu do\u011frulayacak somut kan\u0131tlar aramaya devam etmektedirler.<\/p>\n\n
Albinykus baatar’\u0131n ke\u015ffi, dinozor \u00e7e\u015fitlili\u011fi ve evrimi hakk\u0131ndaki anlay\u0131\u015f\u0131m\u0131z i\u00e7in \u00f6nemli sonu\u00e7lar do\u011furmaktad\u0131r. Bug\u00fcne kadar bilinen en k\u00fc\u00e7\u00fck dinozorlardan biri olarak Albinykus, dinozorlar\u0131n i\u015fgal edebilecekleri ekolojik ni\u015fler ve dinozor t\u00fcrlerinin \u00e7e\u015fitlenmesine yol a\u00e7an evrimsel yollar hakk\u0131nda bilgiler sa\u011flamaktad\u0131r.<\/p>\n\n
