Short summary

This study re-evaluates the characterization of the Permian–Triassic boundary based on high-precision U-Pb geochronology from two marine sections (Dongpan and Penglaitan) with continuous and conformable stage boundaries in the Nanpanjiang Basin (southern China). These new dates provide the basis for a first proof-of-concept study utilizing a Bayesian statistic age–depth chronology comparing these two sections with the Global Stratotype Section and Point at Meishan (western China).
