摘要
通过在上扬子区现有发现的水生爬行动物化石资料，认为中三叠世是贵州龙繁盛时期，兴义顶效贵州龙动物群保存如此之好，丰度之高，实属罕见。其所处的古地理位置及拉丁期海退是形成这个动物群的重要条件，系统研究了该动物群的古生态环境，同时提出在路南、兴仁屯脚等地的古地理环境是贵州龙动物群较佳的古生态环境，也是今后寻找新的贵州龙的有利场所。
Through studing systematically the available data on aquatic reptile fossils from upper Yangtze province, it is found that Middle Triassic was a prosperous period of Kueichousaurus, an naquatic reptile, and Kueichousaurus faunal fossils in Dingxiao of Xingyi area are remarkably abundant and reserved very well. The paleoecologic environmental study shows that regional paleogeographic location and Ladinian regression are the important conditions for prospering the fauna. Lunan area of Yunnan and Tunjiao of Xingren area in Guizhou were in favourable paleogeographic locations for the development of the fauna, and so these areas are a good site to search for new Kueichousaurus fossils in the future.
