In the Kunming region, the Chengjiang fauna-bearing strata of Lower Cambrian Heilinpu Formation, especially the Yuanshan Member are well developed and widely spreaded, having great potential in searching for new localities of the Chengjiang fauna. From 1992 to 1998, sponsored by the Yunnan Provinceial science & Technology Conmission and the Ministry of Geology and Mineral Resources, we carried out searching and exploring of the Chengjiang fosssils round the Kunming region, and about 5000 speciemens were collected at Haikou, Kunming, including abundant soft-bodied arthropods and diversed worms, lophophorates, sponges, brachiopods, hyolithes, macroalgal fossils, uncertain taxa and ichnofossils.
This book gives a detailed introduction about the research history, stratigraphic horizon and geographic distribution of Chengjiang fauna in the kunming region. The classification and composition of the fauna are discussed with comparison to that in the Chengjiang region. The paleoecology and taphonomy of some early taxa are briefly reviewed. It is important to note that a new softbodied fauna, named as Gaunshan fauna is here reported for the first time from the Lower Cambrian Wulongqing Formation in the Kunming region, and a comparison of its composition to the Chengjiang and the malong faunas is made.
Altogether 111 species assigned to 101 genera of 18 fossil groups are described from the Kunming region, among them 48 species and 36 genera are new. They belong respectively to the Chengjiang and Guanshan faunas. The new significant discovery greatly enriches the contents of early faunas and is of great importance for understanding the geological and geographical distribution of the Early Cambrian biotas in eastern Yunnan and their paleoecological and taphonomic environments.
