封面故事：广西那派龙右肠骨及野外化石点现场。广西扶绥那派盆地是我国南方地区最具代表性的早白垩世恐龙化石产地, 最新发现的鸟脚类肠骨、坐骨特征揭示了它们来自恐龙一新属种。广西那派龙是那派盆地被命名的首个鸟臀类恐龙, 也是我国南方地区被命名的第一个基干禽龙类属种, 扩展了我国属种级别的禽龙类化石地理分布范围, 为探讨早白垩世时期中国南方与北方地区之间、中国南方地区与东南亚一带恐龙动物群之间的关系提供了新依据。这项由中国地质科学院地质研究所姬书安研究员主持的研究成果, 详见本期1-10页。（图片提供：姬书安）
Cover Story：Right ilium of Napaisaurus guangxiensis and the fossil quarry in the field. Napai Basin in Fusui County, Guangxi is the most representative fossil site of Early Cretaceous dinosaurs in southern China. The newly discovered ornithopod ilium and ischium belong to a new taxon. Napaisaurus guangxiensis is the first named ornithischian dinosaur in Napai Basin, as well as the first named genus and species of basal iguanodontians in southern China. This finding extends the geographical distribution of diagnostic iguanodontians in the country. Moreover, it provides new evidences for understanding the relationship of dinosaur faunas between southern China and northern China, and those between southern China and southeastern Asia during the Early Cretaceous. The research was led by Professor JI Shu-an, Institute of Geology, CAGS. For details, see pp. 1-10 of this issue. (Photo by JI Shu-an)
