摘要
首次报道了新疆东部沙尔湖煤田中侏罗世17属27种植物大化石和35属50种孢粉化石。该植物群以蕨类、苏铁类及本内苏铁类、银杏类为主要组成成分,时代可能为中侏罗早期。其地质古生物特征表明,该植物群生长的古环境可能为温暖潮湿并具季节性变化的暖温带的湖沼地区。
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.
