摘要: 辽宁省建昌县玲珑塔大西山地区出露的中侏罗统髫髻山组二段含有丰富的动、植物化石,是国家级重点保护古生物化石的产地.通过测制髫髻山组剖面及采集化石,新发现了新疆龟(Xinjiangchelys sp.)和赫氏近鸟龙(Anchiornis huxleyi)等化石产出的新层位,丰富了燕辽生物群的内容,进一步验证了侏罗纪燕辽生物群动物的演化方向.Abstract: The second member of Tiaojishan Formation, Middle Jurassic Series, outcropped in Daxishan area, Western Liaoning Province, yields abundant fossils. During the geological section survey, the fossils of Xinjiangchelys sp., Anchiornis huxleyi and others were founded in new horizons. This discovery enriches the Yanliao Biota and further confirms the biological evolutionary direction of the fauna in Yanliao Biota.
