| 摘 要： | 通过对湘中南区部分剖面晚二叠世大隆组下部层位的系统采样和分析，获取了珍贵的牙形刺资料，其时限为晚二叠世。以大隆组下部所产Ａｌｔｕｄｏｃｅｒａｓ、Ｐａｒａｃｅｌｔｉｔｅｓ等菊石为依据将龙潭组时代全部划入中二叠世晚期（茅口期）的观点是不适宜的。

| Abstract: | Based on the systematic collection and analysis of the lower part of Late Permian Dalong Formation in some sections of Central-Southern Hunan, much valuable information on conodonts have been obtained. It is unsuitable to class the whole Longtan Formation as late Middle Permian only based on the Altudoceras, Paraceltites, etc. contained in the lower part of the Dalong Formation. |
