复兴村下古生界盆地的寒武系,主要分布在集安县的复兴村—治安村一带。前人对该地寒武系研究较差,仅在一比二十万区域地质调查过程中建立了较完整的层序,但因缺少化石依据,地层单元只划分到统。一九八四年六月我们在踏勘一比五万复兴村幅上元古界及下古生界剖面时,在三道沟、下吊子沟、上吊子沟等地,前人划分为上元古界钓鱼台组、南芬组石英砂岩所夹结晶灰岩透镜体中,发现有三叶虫化石(图1),经我所古生物室朱乃文鉴定为Redlichia The Cambrian of the Lower Paleozoic basin in Fuxing Village is mainly distributed in the Fuxing Village - Zhuan’an Village in Ji’an County. The predecessors did not study the Cambrian in this area very well. Only a complete sequence was established during one to two hundred thousand regional geological surveys.

In June 1984, when we surveyed the Paleoproterozoic and Lower Paleozoic sections of Wuxiaoxiang Village in the area of ​​Sandao Ditch, Proterozoic Diaoyutai group, Nanfen group quartz sandstone sandwiched crystalline lens, and found trilobite fossils (Figure 1), identified by our paleontology room Zhu Naiwen Redlichia
