珊瑚 Caninia dorlodoti组合带,系吴望始等(1981)研究华南地区邵东组珊瑚化石时所建立的一个上部化石带,下部为Ceriphyllum elegantum组合带。关于邵东组(段),候鸿飞(1965)、吴望始等(1981)根据其中所产腕足、珊瑚等化石性质,均将其与西欧艾特隆层对比,时代归早石炭世。王成源(1983)研究了从邵东组下部分析出的牙形刺Polygnathus一些分子,认为邵东组时代应属于泥盆纪。宁宗善等(1984)根据广西武宣下石炭统黄茆组中珊瑚、牙形刺化石,把它和邵东组对比,从而将邵东组和艾特隆层归到下石炭统。这种分歧的存在,除了一些认识上的问题外,邵东组的时代问题,实质上是国
Coral Caninia dorlodoti belt, Department of Wang Wushi (1981) to study the South China Shaodong coral fossils established by an upper fossil zone, the lower part of the combination of Ceriphyllum elegantum belt. According to Shaodong Formation (section), Hou Hongfei (1965), Wu Wangshi et al. (1981) compared with the Etretur in Western Europe according to the fossil properties of the brachiatales and corals produced therein, and the period belongs to Early Carboniferous. Wang Chengyuan (1983) studied some molecules of the Polygonathus from the lower part of the Shaodong Formation and concluded that the Shaodong Formation should belong to the Devonian. Ning Zongshan et al. (1984) Based on the corals and conodonts from the Lower Carboniferous Huangpi Formation in Wuxuan, Guangxi, it was compared with that of the Shaodong Formation, and the Shaodong Formation and the Atlasian layer were assigned to the Lower Carboniferous. Except for some problems of understanding, the question of the times in this Shaodong group is essentially a
