Fosil, \u00c7in\u2019in Jehol Biota b\u00f6lgesinde, Erken Kretase devrine ili\u015fkin \u00fcnl\u00fc fosil yataklar\u0131ndan biri olan Yixian Formasyonu\u2019nda ke\u015ffedildi. Bilim insanlar\u0131, bu yeni cinse ‘Jeholia longchengi’ ismini verdi. \u201cJeholia\u201d ismi, 133 ila 120 milyon y\u0131l evvel kuzeydo\u011fu \u00c7in\u2019de var olan Jehol ekosistemine at\u0131fta bulunurken, \u201clongchengi\u201d ise fosilin bulundu\u011fu Longcheng b\u00f6lgesinden geliyor.<\/p>\n

J. longchengi, yakla\u015f\u0131k 10 santimetre (4 in\u00e7) uzunlu\u011funda olup, periyodun \u00f6b\u00fcr akreplerine k\u0131yasla hayli b\u00fcy\u00fck bir t\u0131p olarak bedellendiriliyor. \u201cMesozoik \u00e7a\u011fda ya\u015fam\u0131\u015f \u00f6teki akrepler \u00e7ok daha k\u00fc\u00e7\u00fckt\u00fc, bir\u00e7oklar\u0131n\u0131n uzunlu\u011fu bu yeni \u00e7e\u015fidin yar\u0131s\u0131ndan bile k\u0131sayd\u0131,\u201d diyor ara\u015ft\u0131rman\u0131n ortak muharriri Diying Huang.<\/p>\n

Fosilin en dikkat cazibeli \u00f6zelliklerinden biri pentagonal (be\u015fgen) beden yap\u0131s\u0131 ve yuvarlak teneff\u00fcs a\u00e7\u0131kl\u0131klar\u0131 (spirak\u00fcller) oldu.

Lakin, J. longchengi\u2019nin uzun bacaklar\u0131 ve ince pedipalplar\u0131 (k\u0131ska\u00e7lar\u0131), bilinen akrep tiplerinden farkl\u0131 bir yap\u0131ya sahip oldu\u011funu ortaya koyuyor.<\/p>\n

Bu dev akrep, muhtemelen \u00f6r\u00fcmcekler, kertenkeleler, kurba\u011falar ve k\u00fc\u00e7\u00fck memelilerle besleniyordu.

Mesozoik \u00e7a\u011fdaki akreplerin birden fazla kehribar i\u00e7inde korunmu\u015f olarak bulunurken, bu yeni fosilin kaya katmanlar\u0131nda korunmu\u015f olmas\u0131 epeyce ender bir ke\u015fif olarak bedellendiriliyor. \u201cAkrepler ekseriyetle kayalar\u0131n alt\u0131na yahut kollar\u0131n ortas\u0131na saklanarak ya\u015fad\u0131klar\u0131 i\u00e7in, fosille\u015fme s\u00fcre\u00e7leri epey g\u00fc\u00e7 ve ender ger\u00e7ekle\u015fir\u201d diyen Huang, bu ke\u015ffin de\u011ferine vurgu yap\u0131yor.<\/p>\n

Jehol Biota b\u00f6lgesi, daha evvel dinozorlar, ku\u015flar, memeliler ve b\u00f6cekler \u00fczere bir\u00e7ok canl\u0131 \u00e7e\u015fidine ili\u015fkin fosillere konut sahipli\u011fi yapm\u0131\u015ft\u0131.
