Daha \u00f6nce ba\u015fka hi\u00e7bir dinozorda g\u00f6r\u00fclmemi\u015f olan kuyruk, birbirine kayna\u015fm\u0131\u015f yedi \u00e7ift d\u00fcz, b\u0131\u00e7ak \u015feklinde kemikli pul i\u00e7eriyor.<\/p>\n\n
\u0130skelet, Stegouros elengassen adl\u0131 yeni bir z\u0131rhl\u0131 dinozor t\u00fcr\u00fcne ait. Yakla\u015f\u0131k 72 ila 75 milyon y\u0131l \u00f6nce D\u00fcnya’da ya\u015fam\u0131\u015f ve ankylozavr familya a\u011fac\u0131nda erken bir evrimsel ayr\u0131m\u0131n izlerini ta\u015f\u0131yor olabilir.<\/p>\n\n
Stegouros elengassen, d\u00f6rt ayak \u00fczerinde y\u00fcr\u00fcyen ve iki fitten k\u0131sa boyu ve yedi fit uzunlu\u011fuyla ot\u00e7ul bir hayvand\u0131. Di\u011fer ankylozavr t\u00fcrlerine k\u0131yasla daha az v\u00fccut z\u0131rh\u0131na ve daha ince uzuvlara sahipti.<\/p>\n\n
Dinozorun en belirgin \u00f6zelli\u011fi, Aztek sava\u015f sopas\u0131 macuahuitl ile kar\u015f\u0131la\u015ft\u0131r\u0131lan kuyru\u011fudur. Kayna\u015fm\u0131\u015f, sivri kuyruk, onu korkun\u00e7 bir silaha d\u00f6n\u00fc\u015ft\u00fcren t\u0131ra\u015f b\u0131\u00e7a\u011f\u0131 kadar keskin keratin tabakalar\u0131yla kapl\u0131 olabilir.<\/p>\n\n
Stegouros elengassen’in ke\u015ffi, ankylozavrlar\u0131n erken evrimine \u0131\u015f\u0131k tutuyor. Kuzey yar\u0131mk\u00fcrede bulunan erken ankylozavrlar\u0131n kuyruklar\u0131nda sopalar yoktu; daha sonraki \u00f6rneklerde ise k\u00f6r bir \u00e7eki\u00e7 \u015fekli olu\u015fturan, sertle\u015fmi\u015f omurlardan olu\u015fan kuyruklar geli\u015fti.<\/p>\n\n
Stegouros elengassen’in benzersiz kuyru\u011fu, s\u00fcper k\u0131ta Pangea par\u00e7aland\u0131\u011f\u0131nda ankylozavr familyas\u0131ndaki ana soydan ayr\u0131lan, z\u0131rhl\u0131 dinozorlar\u0131n erken bir evrimsel kolunu temsil edebilece\u011fini d\u00fc\u015f\u00fcnd\u00fcr\u00fcyor. Bu ayr\u0131m, kuzey ve g\u00fcney yar\u0131m k\u00fcrelerde farkl\u0131 ankylozavr soylar\u0131n\u0131n geli\u015fmesine yol a\u00e7m\u0131\u015f olabilir.<\/p>\n\n
Stegouros elengassen’in ke\u015ffi, \u00f6zellikle g\u00fcney yar\u0131m k\u00fcrede ankylozavrlar \u00fczerine devam eden ara\u015ft\u0131rmalar\u0131n \u00f6nemini vurguluyor. Ara\u015ft\u0131rmac\u0131lar, bir zamanlar Gondvana olarak bilinen ve Jura d\u00f6neminde var olan g\u00fcney s\u00fcper k\u0131tas\u0131nda hen\u00fcz ke\u015ffedilmemi\u015f bir ankylozavr soyunun olabilece\u011fini \u00f6ne s\u00fcr\u00fcyorlar.<\/p>\n\n
Stegouros elengassen ve g\u00fcney yar\u0131m k\u00fcreden di\u011fer ankylozavrlar\u0131n daha fazla incelenmesi, paleontologlar\u0131n bu z\u0131rhl\u0131 dinozorlar aras\u0131ndaki evrimsel ili\u015fkileri ve farkl\u0131 ortamlara uyum sa\u011flamalar\u0131n\u0131 anlamalar\u0131na yard\u0131mc\u0131 olacakt\u0131r.<\/p>\n\n
