EARLY JURASSIC LINSHAN FLORA FROM NORTHEAST JIANGXI PROVINCE, CHINA

The compositions, features and times of the flora in the Linshan Formation, Shangrao County, Jiangxi Province have been studied. The plant fossils obtained are identified to be 55 species belonging to 28 genus: 24 known species, 13 similar species, and 18 undetermined species. Of the Linshan flora, Cycadophytes occupied 35.4%; Ferns, 27.3%; Ginkgophytes, 10.9%; Equsietales, 10.9%; and Conifers, Fructus and Stmina, 16.4%. This flora should be classified as Ptilophyllum Coniopteris assemblage in the upper part of the Dictyophyllum Clathrophteris Series in the time equivalent to the Plinensbachian-Toarcian stage, which represents hot and semihumid climate. In a sense, the flora is closely related with the Early Jurassic flora in the middle-lower Changjiang River, for example, the Hsianchi flora of western Hubei, the Wuchang flora of Southeast Hubei, the Xiangshan flora of Anhui and Jiangsu, the Zhenzhuchong flora of northeast Sichuan and so on.
