| Abstract: | A Middle Jurassic flora from the Shaerhu coal field of eastern Xinjiang, China is reported for the first time. The flora consists of 27 species of 17 genera in magafossils and 50 species of 35 genera of palynofossils, at least, and is predominated by ferns, bennettitales, cycadoales and ginkgoales, aged probably in the early Middle Jurassic. Based on the geological and paleontological analyses, the flora was probably living in the area where spread by lake-swamps and under warm and humid climates with seasonal changes during the early Middle Jurassic. |
