| 摘 要： | 我国寒武纪早期含磷岩系中产出丰富的小壳动物化石,其层位居于含老三叶虫动物群的层位之下。这个动物界早期演化的第二阶段--从软身躯演化而来初具硬骨髂的阶段,目前研究甚差,绝灭种类甚多,许多化石是分类位置未定的。1975年后,笔者和其他人先后在四川省峨眉县麦地坪,贵州省织金大院及湖北省宜昌县天柱山的寒武系底部含磷岩系中,用化学法处理出大量图钉形态的小壳化石。

| Abstract: | The strange nail-like fossil Zhijinites discussed was found from the early Lower Cambrian P-bearing sequences in three localities, South China. Similar fossils have been reported recently also in contemporaneous strata of the Siberia platform. |
