Keywords:mass extinction, Chaotian, environmental changes

The end-Paleozoic mass extinction was one of the largest biodiversity crises in the Phanerozoic and had two phases: the biodiversity decline across the middle-late Permian boundary (G-LB) and the abrupt extinction across the Permian-Triassic boundary (P-TB). We present the litho-, bio-, and chemo-stratigraphy across the G-LB and P-TB at Chaotian in northern Sichuan, South China.
