The Alengchu section in western Yunnan currently represents one of the most continuous Lochkovian to Lower Emsian limestone sequences in South China that is suitable for conodont biostratigraphic work. In this study, we have roughly defined the bases of the Lochkovian, Pragian and Emsian, and made a preliminary division of the Silurian. The Lochkovian has been divided into lower, middle and upper parts. In the Pragian the irregularis Zone is based on Pseudogondwania ethingtoni and Latericriodus steinachensis eta morphotype. The succeeding kindlei-pireneae Zone is delimited herein indirectly based on E. trilinearis and Gondwania nevadensis alpha as reference markers. Eocostapolygnathus kitabicus is reported here for the first time in South China. Study of conodont distributions shows that the lower part of the Shanjiang Formation. is Lochkovian in age, its middle and upper parts are Pragian in age, the Alengchu Formation. is earliest Emsian in age. The age of the upper Longmaxi Formation. is probably Wenlock, whereas the Baizitian Formation. corresponds to an interval from the Wenlock through the rest of the Silurian.
