| 摘 要： | 吉林南部晚寒武世凤山期地层出露良好，三叶虫化石丰富，是进行化石群落古生态研究的理想地区。通过埋藏学分析、化石形态功能分析、围岩沉积学研究，在本区建立了六个底栖三叶虫化石群落，自下而上为Ｐｔｙｃｈａｓｐｉｓ－Ｔｓｉｎａｎｉａ群落，Ｑｕａｄｒａｔｉｃｅｐｈａｌｕｓ群落，Ｃｈａｎｇｉａ群落，Ｃａｌｖｉｎｅｌａ群落，Ｍｉｃｔｏｓａｕｋｉａ群落，Ｒｉｃｈａｒｄｓｏｎｅｌａ群落，结合化石群落及其赋存岩性特征，分析本区凤山期沉积环境由前滨－近滨相带渐变为浅海陆棚相带，海水逐渐加深。

| Abstract: | On the basis of functional and taphonomic analysis, six trilobite communities are recognized in the Fengshan Formation of southern Jilin. These are as follows in ascending order: (1) Ptychaspis Tsinania Community, (2) Quadraticephalus Community, (3) Changia Community, (4) Calvinella Community, (5) Mictosaukia Community, and (6) Richardsonella Community. During the Fengshanian time, the marine sediments of southern Jilin were developed from foreshore through nearshore and shallow marine shelf environment. |
