摘要: 本文讨论了中国(江西修水东岭、四川广元上寺和浙江长兴煤山)、印度(克什米尔Guryul Ravine)、前苏联(阿塞拜疆Achura)等地的海相P/T界线层中牙形刺Hindeodus parvus，及其首次出现的点位，阐述了其标准性对海相P/T界线划分的重要意义。建议以产于单相且沉积连续剖面，主齿和细齿均保存完好的Hindeodus parvus的首次出现的点位，作为P/T生物地层界线划分的标准。
Abstract: The article discusses the Conodont Hindeodus parvus in marine P/T boundary layer in China (Dongling Village of Xiushui County, Jiangxi Province; Shangsi Village of Guangyuan City, Sichuan Province; Meishan Town of Changxing County, Zhejiang Province), India (Kashmir Guryul Ravine), and Union of Soviet Socialist Republics (Azerbaijan Achura), and the point location where they appear for the first time. It also explains the important significance of setting criterion for demar-cating marine P/T boundary layer, suggesting that the partition criterion for P/T biostratigraphic boundary would be set on the point locations where they firstly appear in single-phase sediment- successive section, with well-preserved cardinal tooth and serration of Hindeodus parvus.
