Abstract

The Permian–Triassic boundary Global Stratotype Section and Point (GSSP) is located at the Meishan section, Zhejiang Province, South China. The Yinkeng Formation and base of the Helongshan Formation, of Early Triassic Griesbachian age, have been sampled for ostracod analysis for the first time. Twenty-three species were recognized. A new species is described and figured: Bairdia cahuzaci sp. nov. The stratigraphical distributions of all 23 species are given and diversity variations are discussed.
