Series of large conodont samples with 20 species and 3 similar species in 3 genera were collected from the Permian-Triassic （P-T） boundary sequence in a shallow carbonate facies at Yangou （沿沟）, Leping （乐平） County, Jiangxi （江西） Province, South China. On the basis of the distributions of the identified species, seven conodont zones have been recognized in ascending order as follows, Neogondolella changxingensis zone, Neogondolella yini zone, Hindeodus changxingensis zone, Neogon- dolella taylorae zone, Hindeodus parvus zone, Isarcicella staeschei zone, and IsarciceUa isarcica zone. The successive occurrences of Hindeodus changxingensis, NeogondoleUa taylorae and Hindeodus parvus serve as proxies for defining the P-T biostratigraphy boundary at the base of Sub-bed 21-4 of Bed 21 in the Yangou Section. Correlations with the Meishan Section are also discussed in terms of conodont bio-stratigraphy. Three successive conodont faunal assemblages are grouped through the P-T transitional interval to examine the evolution of conodonts across the great transitional event.
