| 摘 要： | 本文通过对黔东南两条新测剖面的整理、已有剖面的进一步挖掘和已有剖面的资料的整理,厘定出几个寒武系第三统底界附近有代表意义的三叶虫属种在这些剖面中产出层位。经过对比研究,认为Oryctocephalus indicus在黔东南分布广泛,个体清晰,层位稳定并延伸较长,可以作为很好的标准化石。

| Abstract: | There has long been an open question concerning the selection of the Global Stratigraphic Section and Point(GSSP) as the boundary between the second series and third series of the Cambrian.Abundant researches have been conducted in China towards the first occurrence of the trilobite Oryctocephalus indicus for defining the base of the third series of the Cambrian.The examination and correlation of several sections in Guizhou show that the trilobite Oryctocephalus indicus is characterized by widespread occurrence,well-defined individuals,stable horizon,and lateral extension,and thus may be selected as an excellent index fossil. |
