文中详细描述昆明地区下寒武统沧浪铺组乌龙箐段古虫动物新种Vetulicola longbaoshanensis sp.nov.,并与相关属种作比较和讨论。古虫动物主要产于下寒武统筇竹寺组玉案山段的澄江动物群中,沧浪铺组乌龙箐段的地质年代较澄江动物群晚,该发现对研究古虫动物的演化具有重要意义。古虫动物的分类位置至今难以确定,争论的焦点多集中在古虫动物前体鳃囊的构造解释上。新材料鳃囊保存得完整清晰,为研究古虫动物的分类位置提供了新证据。
The article describes in detail the new species of Vetulicola longbaoshanensis sp. Nov. From the Wulongpu Formation of the Lower Cambrian in the Kunlun area, and compares and discusses with related species. The ancient animals were mainly found in the Chengjiang fauna in the Yushan section of the Qiongzhusi Formation in the Lower Cambrian. The geologic age of the Wulongwan Formation in the Canglangpu Formation was later than that of the Chengjiang fauna, It is of great significance. The classification of the ancient animals has so far been difficult to determine the location of the debate, most of the focus on the ancient animal body gill capsule anatomy explanation. The new material gill sac preservation complete and clear, for the study of the classification of the ancient beetle animals provide new evidence.
