| 摘 要： | 记述了贵州兴义法郎组竹杆坡段鸥龙的一新种──兴义鸥龙(Ｌａｒｉｏｓａｕｒｕｓ ｘｉｎｇｙｉｅｎｓｉｓ ｓｐ．ｎｏｖ．)。兴义鸥龙以其上颞孔是眼眶长度的两倍,顶骨平台细长而不收缩,肱骨缺失外髁沟和旋后肌突,及肱骨短于股骨而有别于鸥龙的其他种。兴义鸥龙与意大利拉丁晚期的Ｌａｒｉｏｓａｕｒｎｓｖａｌｃｅｒｅｓｉｉ最为相似。依据脊椎动物的对比,法郎组竹杆坡段的时代应为中三叠世晚期。

| Abstract: | The first Triassic sauropterygian to be described from China was Keichousaurus hui (Young, 1958) found in Xingyi, Guizhou. Shingyisaurus unexpectus, another sauropterygian found in Xingyi, was referred to the Simosauridae by Young (1965). It was identified as Nothosaurus or a closely related genus, and the name Shingyisaurus unexpectus was considered a nomen dubium (Rieppel, 1998). Here we report a well-preserved specimen from Xingyi, Guizhou Province. It represents the first undoubted specimen and a new species of Lariosaurus ever found outside western Tethyan faunal province. |
