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.
