Communications Biology’de yay\u0131nlanan son bir ara\u015ft\u0131rma, \u00c7in’in Linxia Havzas\u0131’nda g\u00fcn y\u00fcz\u00fcne \u00e7\u0131kar\u0131lan k\u0131smi kal\u0131nt\u0131lara dayanarak, bu devasa memelinin Paraceratherium linxiaense adl\u0131 yeni bir t\u00fcr\u00fcn\u00fcn ke\u015ffini ortaya koymaktad\u0131r.<\/p>\n\n
Bu tarih \u00f6ncesi dev, \u00e7a\u011fda\u015flar\u0131n\u0131n \u00fczerinde y\u00fckselerek 16 fit gibi \u015fa\u015f\u0131rt\u0131c\u0131 bir y\u00fcksekli\u011fe ula\u015f\u0131yordu. 3,8 fit uzunlu\u011fundaki devasa kafatas\u0131, modern bir tapire benzer \u015fekilde uzun ve kal\u0131n bir boynu ve k\u0131sa bir hortumu destekliyordu. Derin bir burun bo\u015flu\u011fu, keskin bir koku alma duyusunu d\u00fc\u015f\u00fcnd\u00fcrmektedir.<\/p>\n\n
Dev gergedan, g\u00fcn\u00fcm\u00fcz\u00fcn en b\u00fcy\u00fck fillerini bile g\u00f6lgede b\u0131rak\u0131yordu. Sa\u011flam g\u00f6vdesi 26 fit uzunlu\u011fa kadar uzan\u0131yor ve 11 ila 20 metrik ton a\u011f\u0131rl\u0131\u011f\u0131ndayd\u0131 – bu da \u00fc\u00e7 ila be\u015f Afrika filine e\u015fitti. Z\u00fcrafa benzeri, sa\u011flam bacaklar\u0131, muazzam boyutuna ra\u011fmen \u00e7evik hareket etmesini sa\u011fl\u0131yordu.<\/p>\n\n
Dev gergedan fosilleri, \u00c7in’den Pakistan’a kadar t\u00fcm Asya’da ortaya \u00e7\u0131kar\u0131ld\u0131. Paraceratherium linxiaense’nin \u00c7in’de ke\u015ffi, co\u011frafi da\u011f\u0131l\u0131m\u0131m\u0131z hakk\u0131ndaki anlay\u0131\u015f\u0131m\u0131z\u0131 geni\u015fletiyor ve g\u00f6\u00e7 modellerine \u0131\u015f\u0131k tutuyor.<\/p>\n\n
Dev gergedanlar, de\u011fi\u015fen \u00e7evresel ko\u015fullara kar\u015f\u0131 dikkat \u00e7ekici bir uyum sergilemi\u015flerdi. Oligosen’in erken d\u00f6nemlerinde, Orta Asya’daki kurak ko\u015fullar onlar\u0131 daha ye\u015fil otlaklar aramak i\u00e7in g\u00fcneye g\u00f6\u00e7 etmeye y\u00f6neltti. \u0130klim Oligosen’in ge\u00e7 d\u00f6nemlerinde bir kez daha de\u011fi\u015fti\u011finde, tekrar kuzeye do\u011fru yola \u00e7\u0131kt\u0131lar.<\/p>\n\n
Paraceratherium linxiaense’nin omur fosilleriyle kan\u0131tlanan esnek boynu, a\u011fa\u00e7lar\u0131n en y\u00fcksek yapraklar\u0131na ula\u015fmas\u0131n\u0131 sa\u011flayarak beslenme se\u00e7eneklerini geni\u015fletiyordu. Z\u00fcrafalar\u0131nkine benzer ince bacaklar\u0131, h\u0131zl\u0131 hareket etmesini sa\u011fl\u0131yordu.<\/p>\n\n
Yeni t\u00fcr\u00fcn analizi, Pakistan’da bulunan dev bir gergedan olan Paraceratherium bugtiense ile yak\u0131n bir akrabal\u0131k ortaya koymaktad\u0131r. Bu, Orta Asya boyunca olas\u0131 bir g\u00f6\u00e7\u00fc i\u015faret ederek dev gergedan t\u00fcrlerinin \u00e7e\u015fitlenmesine katk\u0131da bulunmu\u015ftur.<\/p>\n\n
Tibet’te dev gergedan fosillerinin varl\u0131\u011f\u0131, b\u00f6lgenin her zaman bug\u00fcn bildi\u011fimiz y\u00fcksek irtifa platosu olmad\u0131\u011f\u0131n\u0131 d\u00fc\u015f\u00fcnd\u00fcrmektedir. Milyonlarca y\u0131l \u00f6nce, bu devasa memelilerin ge\u00e7mesine izin veren ovalar\u0131n olmas\u0131 muhtemeldi.<\/p>\n\n
Devam eden \u00e7al\u0131\u015fmalar, fosil kal\u0131nt\u0131lar\u0131n\u0131n 3B taramalar\u0131n\u0131 kullanarak Paraceratherium linxiaense’nin kas sistemini yeniden yap\u0131land\u0131rmay\u0131 ama\u00e7lamaktad\u0131r. Bu, v\u00fccut k\u00fctlesinin daha do\u011fru bir tahminini sa\u011flayacak ve adaptasyonlar\u0131 ve davran\u0131\u015flar\u0131 hakk\u0131nda daha fazla bilgi verecektir.<\/p>\n\n
Paraceratherium linxiaense fosilleri \u015fu anda \u00c7in’deki Hezheng Paleozooloji M\u00fczesi’nde sergilenmektedir.
