摘要
采自福建福鼎南溪“构造天窗”的样品分析后获牙形刺。西部所采样品含StreptognathodusfuchenensisZhao,s.elongatusGunnell,Gondolellasp.其时代为晚石炭世晚期。原来这段地层划为下石炭统，应作修改。北部所采样品含IdiognathodusdelieatusGunnell,Neognathodusbassleri(HarrisetHollingsworth),Gondolellasp.其时代为中石炭世早期．进一步证实中石炭统地层的存在。
The conodonts illustrated in this paper were collected ftom the tectonic window in Fuding area of Fujian province. The conodont fauna sampled from the western part, including Streplognathodus fuchenensis Zhao, S. elongatus Gunnell, Gond olelIa sp., indicates a late Carboniferous age. So the previous assignment of Lower Carboniferous should be revised. The conodont fauna sampled from the Northern part, including Idiognathodus delicatus Gunnell,Neognathodus bassleri (Harris et Hollingsworth), Gond olella sp., indicates a Middle Carboniferous age. The existance of Middle Carboniferous is affirmed.
