近日，由中国科学院南京地质古生物研究所研究员王光旭和研究员詹仁斌共同组织的专辑《华南扬子台地西缘的奥陶系》，在国际地学期刊《远古世界》（Palaeoworld）上正式出版。
华南板块具有丰富、完整、连续的奥陶纪地质记录，是理解奥陶纪生命演化的经典地区。不过，华南奥陶系的研究以往主要集中在扬子台地腹地，而对于台地西缘近岸浅水区的认识较少，区内奥陶系的划分对比不够精细，各门类化石大多还未得到系统的研究。
专辑共收录研究论文9篇，涉及华南扬子台地西缘奥陶系精细地层框架的建立，关键层段沉积背景分析，以及主要化石类群（腕足动物、珊瑚、牙形类、几丁虫、介形虫和三叶虫等）系统分类、生物地理与生态等方面的探讨。该专辑是对研究区奥陶系研究最新进展的系统梳理和集中展示，增进了对奥陶纪生物大辐射（GOBE）和奥陶纪末生物大灭绝（EOME）等重大生物事件在华南近岸浅水区表现的认识和理解。
专辑相关研究得到了现代地层学与古生物学国家重点实验室、国家自然科学基金委、江苏省自然科学基金委、中国科学院青年创新促进会等联合资助。
