在贵州剑河巴朗地区松山和交邦剖面的新采样，为三叶虫精确分带的定义提供了新的资料。根据收集到的数据（从下向上）划分了三个新的区域：1)都云山稻穗带（orytocarella duyunensis acme Zone）；2)沙头关节炎（arthroiccephalus chauveaui）；3)巴郎组和“青苏亭”组的北极原头鲸。此外，三叶虫组合分析显示华南与北格陵兰具有较好的相关性。这些三叶虫属于寒武纪二系第4期的FAD。
New sampling in the Songshan and Jiaobang sections near the Balang area, Jianhe, Guizhou, South China, provides new data for definition of an accurate trilobite zonation. Three new zones are defined according to the collected data ( from bottom to top ): 1) Oryctocarella duyunensis acme Zone; 2) Arthricocephalus chauveaui; and 3) Protoryctocephalus arcticus through the Balang and “Tsinghsuting” Formations. In addition, the analysis of the trilobite assemblage in these zones shows a good correlation between South China and North Greenland. The Arthricocephalus chauveaui of these trilobite is FAD of stage 4 of Cambrian series 2.
