This paper deals with the conodonts from the Shaiwa Group (the 3rd Member) in Sidazhai area, Ziyun County, Guizhou Province, South China, comprising 8 genera, 3 species, 1 conformis species and 6 indeterminate species. Based on the components of the conodont assemblage and the phylogenetic analysis of the Sweetognathus group, the conodont assemblage is of an age of Middle Permian (Maokouan), and the conodontbearing strata are certainly assigned to upper Middle Permian. It implicates that the Shaiwa Group not only includes Late Permian sediments, but also late Middle Permian deposits.
