本文报导了滇西晚寒武世晚期的三叶虫动物群,在此描述了9科、16属、19种,其中包括4个新属、10个新种。Saukiidae和Kaolishaniidae两科占主要地位。滇西这一动物群属于华北型动物群,与我国东北、华北、滇越交界、泰国、澳大利亚昆士兰西部等地动物群关系密切。目前我们可将该动物群分为二个组合:下组合是Kaolishania-Kaolishaniella组合,相当于长山阶的Kaolishania带和北美的Franconian阶Conaspis带;上组合是“Calvinella”-Lonchopygella-Quadraticephalus组合,相当于凤山阶上部、澳大利亚的Payntonian阶和北美的Trempealeauan阶。
This article reports on the trilobite fauna in the Late Late Cambrian of Western Yunnan, describing 9 families, 16 genera and 19 species, including 4 new genera and 10 new species. Two subjects, Saukiidae and Kaolishaniidae, dominate. The fauna belongs to the North China type fauna in western Yunnan and has close relations with the fauna in northeastern China, northern China, Yunnan and Vietnam, western Thailand and Thailand. Currently we can classify the fauna into two combinations: the lower combination is the Kaolishania-Kaolishaniella combination, which corresponds to the Kaolishania belt in the long mountain order and the Franconian Conaspis zone in North America; the upper combination is the combination “Calvinella” -Lonchopygella-Quadraticephalus, Upper Yufengshan, Payntonian in Australia and Trempealeauan in North America.
