Language: Chinese
This book brings together a group of experts in Ordovician (485-444 milliong years ago) stratigraphy and palaeontology research in China, covering palaeontology, biostratigraphy, petrostratigraphy, chronostratigraphy, chemical stratigraphy, event stratigraphy, quantitative stratigraphy, ecological stratigraphy, sedimentary science, sedimentary geochemistry and other disciplines. A total of 175 fossil plates are collected in this book, including 33 graptolites, 17 conodonts, 37 brachiopods, 19 trilobites, 25 cephalopods, 15 chitinoids, and 9 suspected sources, 8 radiolarians, 9 corals, and 3 foraminifera. Except for corals and stratoforaminae, which were mainly limited to the Late Ordovician, other phyla basically covered the entire Ordovician and formed a multi-phylum biostratigraphic sequence throughout the Ordovician from different perspectives of biological belts, biological communities, and biological assemblages.
Summary in Chinese:
本书集结了我国奥陶纪地层和古生物研究的一批专家,涉及古生物学、生物地层学、岩石地层学、年代地层学、化学地层学、事件地层学、定量地层学、生态地层学、沉积学、沉积地球化学等学科。
本书共汇集了化石图版175个,其中笔石33个、牙形类17个、腕足动物37个、三叶虫19个、头足类25个、几丁虫15个、疑源类9个、放射虫8个、珊瑚9个、层孔虫3个。除了珊瑚和层孔虫主要限于晚奥陶世外,其他门类基本上涵盖了整个奥陶纪,从生物带、生物群落、生物组合的不同角度形成了贯穿奥陶纪的多门类生物地层序列。
