| 摘 要： | 贵州中晚三叠世的海生爬行动物以鳍龙类为主，另有鱼龙类。主要产出层位有二个，即中三叠统安尼阶的关岭组及晚上三叠统卡尼阶的竹杆坡组和瓦窑组。它们仅见于贵州中晚三叠世的碳酸盐台地范围内，在深水陆源碎屑浊积盆地尚未见及，化石以原地埋藏为主，异地埋藏很少见及。多数属种特征与欧州阿尔插斯的同期类群料为接近，而与北美同期类群料为疏远。

| Abstract: | Sauropterygids occurs as the dominated thalassophile reptiles in middle-upper triassic of Guizhou , another as Ichthyosaurids. The chief horrizon of occurrence is included into Guanling formation in Anisian age of middle triassic and Zhuganpo group and Wayao group in Carian stage of upper triassic. They have only been founded within the range of carbonate platform in middle-upper triassic, but never occur in the basin of terigenous detrial sendiment of deep seated water.The burial of fossiles give priority to the former place, and seldom be seen in the other place. Most of species feature approaches to the categories at the same period in European alpine vein, and differ from the categories at same period in north American |
