The taxonomy and stratigraphic distributions of conodonts from the Permian-Triassic boundary beds of the Liangfengya Section at Zhongliang Hill,Chongqing,are described. Based on their stratigraphic distribution,the changeover from the Clarkina-dominated to the Hindeodus-dominated populations of conodonts occurs in the horizon between samples 30~1 and 30~2. At this horizon, numerous associated brachiopod, fusulinid and coral species also disappeared except for a few small and thin-shelled brachiopods which survived into the basal Triassic. This extinction pattern is generally comparable with that at the Meishan Section in terms of timing and diversity change. The Permian-Triassic boundary at the Liangfengya Section is at the base of Bed 34 as indicated by the first occurrence of the conodont Hindeodus parvus.
