青海祁曼塔格出一带的Kepingophyllum珊瑚动物群

RECORDS OF THE KEPINGOPHYLLUM CORAL FAUNA FROM MT. QIMANTAGE OF QINGHAI

青海祁曼塔格山一带打柴沟组的珊瑚化石是近岸底栖、浅海相的块状复体四射珊瑚，属于晚石炭世至早二叠世过渡性质的Ｋｅｐｉｎｇｏｐｈｙｌｌｕｍ珊瑚动物群，共７属１９种，其中１新属和１４新种。这些珊瑚的个体外壁由泡沫板和隔壁分化演变而成，它们与华南及西南地区相应时代中的珊瑚关系密切。

The KepingOPhyllum coral fauna under study was collected from the Upper Carboniferous --Lower Permian Dachaigou Formation in the Qimantage mountains district,Qinghai. This formation, about 131--195m in thickness, yields the fusulinidsSPhaeroschwagerina, Pseudoschwagerina, Zellia, Pseudofusulina, EOParafusulina, Schwagerina, Quasi'fusulina, Boultont'a, Schubertella, Paraschwagerina, Rugosofusulina, Staffella,etc. Based on these symbiotic fusulinids,the KepingOPhyllum coral fauna is attributed tolate Late Carboniferous in age. This coral fauna is composed of 7 genera and ZI species intotal (including I new genus and 16 new species ), namely, Antheria polygonalis Wu etZhao. A' naotica sp. nov.,A. rara sp. nov., Nephelophyllum antheiroidea sp. nov.,Kepingthphyllum cursatum sp. nov.,K. proll'ferum sp. nov.,AnfractOPhyllum facetum Wu et Zhou,A. facetum minor Wu et Zhou,A. dupliforme Wu et Zhou,wu et Zhou,A. lytintontum sp.590 $l to 9 m $349nov., A. perfaclum sp. nov., A. grossum sp. nov., EokepingOPhyllum simplex X. Yu, E.dt'fforme sp. nov., E. delicalum sp. nov., ProkepingOPhyllum typicum gen. et sp. nov., P.minor gen. et sp. nov., P multiforme gen. et sp. nov. and Yokoyamaella multiseptala sp.nov. Among them,Nephelophyllum has been found from the Maping Formation in westernGuizhou (Wu Wang--shi et al., 1974 ),and Jiangyou, Sichuan (Fan Ying--man, 1978 ),and the' Upper Carboniferous in Zadoi,Qinghai (Li Zhang--rong et al., 1979), but it also has beenfound in the lower part of the Lower Permian in Zhanyi,Yunnan (Wu Wang--shi et al.,1982), while N. antheriaoidea is similar to N. yunnanense Wu et Kong, 1982 from thefusulinid Robustos chwagerina Zone of Guangnan, Yunnan. Antheria is distributed in theMaping Formation of western Guizhou (Wu Wang-shi et al., 1974 ), Longlin, Guanxi(Zheng Chun--n, 1986 ),Ceheng,Guizhon (Wu Wang--shi et al., 1982 ),and Daxin,Guangxi(Jia Hut--zhen and Xu Shou--yong, 1978),and the Jinhe Formation of inner Mongolia (GuoSheng-zhe, 1983),but it also has been found in the lower part of the Lower Permian (WuWang--shi et al., 1988). KepingOPhyllum is known to occur in the Kangkelin Formation ofKalpin and Baicheng, Xinjiang (Wu Wang-shi et al., 1982 i Cat Tu-ci, 1986 ), the MapingFormation of western Guizhou (Wu Wang-shi et al., 1979 ), and Nanning, Yishan ofGuangxi (Zheng Chun--n, 1986),and the Chuanshan Formation of southern Jiangsu (YuXue--guang, 1980) 1 in recent years,this genus also has been found from the lower part ofthe Lower Permian in Zhanyi, Yunnan, Pan-clan and Weining,Guizhou (Wu Wang--shi etal., 1988), and from the fusulinid Pseudoschwagerina zone (Lower Permian) in Sumatraaccording to Fontaine' S (1986) report. Anfractophyllum is known to occur in the Kangkelin Formation of Kalpin,Xinjiang (Wu Wang-shi et al., 1982),the fusulinid Robustochwagerina zone of Guangnan,Yunnan (Wu Wang-shi et al., 1982) and the Maping Formationof Long im,Guizhou (Wu Wang--shi et al., 1988),but also has been found from the lowerpart of the lower Permian in Zhanyi,Yunnan (Wu Wang-shi et al., 1988),and is in coexistence with Polythecalis of early Early Permian in Laibin, Guangxi. EodepingOPhyllum isknown to occur in the Chuanshan Formation of Jiangsu (Yu Xue--guang, 1980) and theKangkelin Formation of Baicheng, Xinjiang (Cat Tu--ci, 1986) 1 recently, it also has beenfound from the Chuanshan Formation of Jiangxi. YOkoyamaella was first known to occur inthe Lower Permian of Japan, and also has been found from the fusulinid Pseudoschwagerina zone of Alps (Heritsch, 1936), the Lower Permian Bingfeng Formation of Batang,Sichuan (Wu Wang--shi el al., 1979),the Maping Formation of Longlin,Guangxi (ZhengChun-n, 1986) and Weining, Guizhou (Wu Wang--shi et al., 1988). The present horizonscontaining Antheria and NephelOPhyllum are lower than, while the horizon containingYokoyamaella is higher than those containing other corals in this region.
