New discovery of Devonian conodonts in the Dalongtang area,Gengma ,southwestern Yunnan,and their stratigraphic significance

摘要: 在耿马东部大龙塘等地的硅质岩系中新发现大量牙形石，可建立两个牙形石带：Palmatolepis gigas带、Palmatolepis triangularis带。此套含牙形石硅质岩系的时代属于晚泥盆世弗拉斯阶—法门阶，对比为曼信组。

Abstract: Plenty of conodonts were discovered in siliceous rock series in Dalongtang area in the east of Gengma ,Yunnan,and two conodont zones are recognized:the Palmatolepis gigas Zone and Palmatolepis triangularis Zone.This conodont-bearing siliceous rock series is Upper Devonian Frasnian-Famennian in age and can be correlated with the Manxin Formation.
