摘要
提要描述的珊瑚化石采自塔里木盆地西部伽师县西克尔地区,含珊瑚的地层是兰多维列统的柯坪塔格组。柯坪塔格组是目前塔里木盆地唯一有珊瑚的志留纪地层,西克尔又是塔里木盆地仅知有柯坪塔格组珊瑚动物群的地区,对我国志留纪古生物地理区系研究有重要意义。文内描述的柯坪塔格组珊瑚动物群包含床板珊瑚2属3种,日射珊瑚1属2种和皱纹珊瑚1属1种,属种名单是Paleofavosites schmidti Sokolov,P.schmidti borealis Sokolov,Schedohalysites raregonopora sp.nov.,Mcleodea jiashiensis sp.nov.,M.xikeerensis sp.nov.和Kodonophyllum cf.undulatun He and Huang。
The coral fauna dealt with in this paper was collected from Xikeer in Jiashi County, Xinjiang, in the Western Tarim Basin. The coral-bearing strata are assigned to the middle-lower part of the Kolpingtag Formation, of Lower Llandovery age. Xikeer is the only locality with Early Llandoverian corals in the Tarim Basin and hence is of considera- ble palaeobiogeological interest within the Silurian of China as a whole. The coral fauna includes fol- lowing species. Paleofavosites schmidti Sokolov, P. schmidti borealis Sokolov, Schedohalysites raregonopora sp. nov., Mcleodea jiashiensis sp. nov. , M. xikeerensis sp. nov. , and Kodonophy- llum cf. undulatum He and Huang.
