They were confirmed by dinosaur experts from the Zhejiang Museum of Natural History to be those of Mesozoic herbivorous dinosaurs （Fig. 1）. Not long before, Yiwu Museum staff had discovered dinosaur eggs close by this place.展开更多
Two Mesozoic intramontane basins are developed in the Dunhuang-Yumenguan-Jiuquan area of Gansu Province,China,i.e.,the Gongpoquan Basin（E97°30′-98°10′,N41°30′-41°45′）and the Yujingzi Basin（E...Two Mesozoic intramontane basins are developed in the Dunhuang-Yumenguan-Jiuquan area of Gansu Province,China,i.e.,the Gongpoquan Basin（E97°30′-98°10′,N41°30′-41°45′）and the Yujingzi Basin（E98°15′-99°00′,N40°15＇-40°40＇）（Fig.1）.A large number of dinosaurs and other fossils have been discovered in these two basins,which are called dinosaur＇tribes＇by paleontologists.展开更多
