| 摘 要： | 近年来,由于大量采用化学处理法弥补了野外采集和机械处理的不足,在我国的寒武纪早期的含磷岩系中发现了丰富而多样的小壳动物化石,计有软舌螺类、似软舌螺类、腹足动物、海绵动物、似牙形石以及大批分类位置不明的化石。这些发现为地层的细分与对比、矿床成因与古地理分析以及探讨动物界的早期演化规律提供了丰富的材料。本文报道了发现于陕南宁强县宽川铺寒武纪早期地层的群体动物化石,并记述一种似牙形石化石。

| Abstract: | Three fossil forms of uncertain affinity are deseribed here. Two of them. Carinachites tetrastichus Chen and Dabashanites minis Chen, probably represent the early ancestors of tube-building colonial animals that were significant to post-Cambrian geological processes, so they serve as very useful materials for studying the revolutionary process of this kind of animals. The last one is Protohertzina anabarica Miss, associated with the former two and Anabarites trisulcatus Miss., etc. appears to have great stratigraphic importance. |
