The Kuyak Rift is located to the southeast of Minfeng (民丰) County, Xinjiang, and belongs to the western part of the Altun tectonic system. The well-developed section of the Rift about 300 km long and 10—20kin wide, starts from Lhazhulong in Xizang (Tibet) and ends in the southern margin of the Tarim Basin. In the northern part of the Rift stands over the accumulated terraces an abandoned castle called the 'Kuyak' pass served as the key to Xizang in ancient times. However, 展开更多

In Dashanpu, Zigong, Sichuan Province there is a large cluster of Middle Jurassic dinosaur fossils which is confined to an area of less than 3000m^2 in the sand body. From there several hundred pieces of fossils, identified as of different sorts of dinosaurs and other paleovertebrate animals such as Pliosaurus and Pterosaurus, have been excavated out, including about 20 complete or relatively complete skeletons. This fact has naturally attracted the attention of a great many geologists and paleontologists both at 展开更多
