Biostratigraphy of the early Cambrian small skeletal fossils from the Niuniuzhai section of southern Sichuan in China
The Niuniuzhai section in Leibo County, southern Sichuan, China, is part of the western carbonate platform of the Yangtze Block. The section is crucial for correlating early Cambrian successions in the eastern Yunnan and southern Sichuan areas. A comprehensive biostratigraphic analysis of small skeletal fossils (SSFs) from this section identifies three SSF assemblages: (1) the oldest from an interval of uncertain age affinity in the middle and upper Dahai Member of the Zhujiaqing Formation; (2) the Watsonella crosbyi Assemblage Zone (Zone Ⅲ) in the upper Dahai Member of the Zhujiaqing Formation; and (3) the Sinosachites flabelliformis–Tannuolina zhangwentangi Assemblage Zone (Zone IV) in the middle Shiyantou Formation. These SSF assemblage zones in the Niuniuzhai section correlate well with sections from eastern Yunnan and southern Sichuan, indicating a coherent Terreneuvian succession on the the Yangtze Platform and in other continents.
期刊介绍：
Palaeoworld is a peer-reviewed quarterly journal dedicated to the study of past life and its environment. We encourage submission of original manuscripts on all aspects of palaeontology and stratigraphy, comparisons of regional and global data in time and space, and results generated by interdisciplinary investigations in related fields. Some issues will be devoted entirely to a special theme whereas others will be composed of contributed articles. Palaeoworld is dedicated to serving a broad spectrum of geoscientists and palaeobiologists as well as serving as a resource for students in fields as diverse as palaeobiology, evolutionary biology, taxonomy and phylogeny, geobiology, historical geology, and palaeoenvironment.
Palaeoworld publishes original articles in the following areas:
•Phylogeny and taxonomic studies of all fossil groups
•Biostratigraphy, chemostratigraphy, chronostratigraphy
•Palaeoecology, palaeoenvironment and global changes throughout Earth history
•Tempo and mode of biological evolution
•Biological events in Earth history (e.g., extinctions, radiations)
•Ecosystem evolution
•Geobiology and molecular palaeobiology
•Palaeontological and stratigraphic methods
•Interdisciplinary studies focusing on fossils and strata
