摘　　要：苔藓植物几乎在所有的陆地生态环境中均有分布,是种数上仅次于被子植物的第二大高等植物类群。笔者首次系统报道了发现于内蒙古宁城盆地中侏罗世地层中的似藓属Muscites化石,并建立了2个新种:小叶似藓(新种)Muscites microphyllu s sp.nov.Na et Li和密叶似藓(新种)Muscites pycnophyllus sp.nov.Na et Li。新种的发现丰富了宁城盆地中侏罗世苔藓植物化石记录,同时对研究该类群的分布与演化,分析宁城盆地中侏罗世时期地理、气候和环境提供了重要的化石证据。Bryophytes,as the second largest group of higher plants in terms of species after angiosperms,spread over the world in almost all terrestrial habitats.The authors present the first record of fossil Muscites from the Middle Jurassic strata in the Ningcheng Basin,Inner Mongolia,China.Two new species,Muscites microphyllus sp.nov.Na et Li and Muscites pycnophyllus sp.nov.Na et Li were established.The discovery of new species not only enriches the Middle Jurassic fossil record of the Ningcheng Basin,but also provides fossil evidence for studying the distribution and evolution of this group and analyzing the geography,climate and environment of the Ningcheng Basin during the Middle Jurassic.
