封面故事：云南罗平县幻龙足迹。新发现的数百枚保存完好的罗平双桨迹为研究幻龙运动模式提供了直接证据。罗平生物群拥有海生爬行类、鱼类等十多个大类的化石,是目前分异度最高的三叠纪海生化石库之一。处于食物链顶层的海生爬行类的繁盛,说明当时生态系统已臻完善,代表了二叠纪末生物大灭绝后海洋生态系统的全面复苏。这项由中国地质调查局成都地质调查中心张启跃、胡世学主持的研究成果,当选2014年度中国地质调查局、中国地质科学院十大科技进展,排名第六。详见本期385-393页。(图片提供:张启跃)
Cover Story：Nothosaur footprint in Luo- ping County, Yunnan Province. The newly- discovered several hundred pieces of well- preserved Dikoposichnus luopingensis provide direct evidence for the study of the movement pattern of the nothosaur. The Luoping biota possesses more than ten categories of fossils, such as marine Reptilia, fish, Arthropoda and plant, and thus serves as one of the Triassic marine fossil- lagerstattens with the highest degree of diversity. The flourishing of the marine Reptilia at the top layer of the food chain shows that the ecological system had attained perfection at that time and represents the overall recovery of the marine eco-logical system after the mass extinction of the living things in Permian. The research achievement led by Professor ZHANG Qi-yue and HU Shi-xue, Chengdu Center of Geological Survey, China Geo-logical Survey, ranks the sixth among “Top Ten Geological Sci-tech Progresses of China Geological Survey(CGS) and Chinese Academy of Geological Sciences(CAGS) in 2014”. For details, see page 385-393 of this issue. (Photo by ZHANG Qi-yue)
