华南中–晚奥陶世头足类动物群及其古生物地理学研究

中–晚奥陶世是全球构造背景和生物演化的重要转折时期，也是头足类演化历史上多样性爆发、动物群频繁演替以及生物地理分异的关键时期。本研究拟以华南地区中–晚奥陶世头足类为主要研究对象，开展系统古生物学和古生物地理学研究，通过分支系统学、定量古生物地理学等分析手段，诠释该时期头足类动物群的基本面貌和演替机制，结合周边地区同期地层中的头足类化石记录，揭示该地区头足类的古生物地理演化过程，促进对奥陶纪大辐射事件的深入研究。

The Middle–Late Ordovician interval recorded a critical transition of global tectonics and biotic evolution, and was a crucial time interval of explosive diversification, frequent faunal replacement and palaeobiogeographic differentiation of cephalopods. In this study, systematic palaeontologic and palaeogeographic approaches are adopted to investigate the Middle–Late Ordovician evolution of cephalopod faunas in South China. By using the methods of cladistic systematics and quantitative palaeobiogeographic analysis, we aim to elucidate the characteristics and replacement patterns of cephalopod faunas, in order to provide a new perspective on the GOBE.
