The Qaidam Basin is situated in northwestern Qinghai Province, where the Jurassic coal-bearing strata are distributed in the northeastern basin borders and on both sides of Mt.Aimunike, ranging from the Ledong River in the west to the Zawuzui of Wulan County in the east, covering a zonal area of abouth 350km in length. The Jurassic coal-bearing deposits in Dameigou area of Da Qaidam are well-developed, with complete outcropping, simple structure and clear sequence. This area is rich in plant fossils, a part of which are preserved as compression with some carbonaceous films (cuticles) which could be examined microscopically. It is an excellent and representative section in the study of the Lower and Middle Jurassic Series as well as their floras and floral interchanges in Northwest China.
The fossil plants are much more abundant in the studied area, about 206 species belonging to 66 genera being identified. Here are described and illustrated about 188 species with 42 new species in 63 genera. ……
