Abstract: The Middle Jurassic Yan’an Formation in the Northeastern Margin of Erdos Basin belongs to a succession fluvial and shore facies middlefine grained feldspar sandstone, siltstone (pelitic siltstone), black shale, claystone intercalated with coal seams, in which there occur many plant fossils of 39 species belonging to 20 genera. It is considered that the fossils belong to the North Floristic province represented by ConiopterisPhoenicopsis in the early Middle Jurassic. This indicates that the Northeastern Margin of Erdos Basin had a slightly humid and warm climate condition in the age of the Middle Jurassic.
Key words: Erdos Basin, Middle Jurassic, plants fossil, warm climate
