内蒙古中部早白垩世地层发育，植物化石保存较好，许多植物化石还没有系统的描述和报道。本文研究了古阳县西部西连瑙堡村下白垩统古阳组灰黑色泥岩和灰绿色、黄绿色粉砂质泥岩中采集的植物化石。根据保存条件和岩性特征，推测研究区存在准地埋藏和异地埋藏类型，化石植物应处于早白垩世温暖湿润的亚热带气候下。
Early Cretaceous strata in the middle Inner Mongolia are well-developed,and contain well preserved plant fossils,many of which have not been systematically described and reported.This paper studies the fossil plants collected from the ash black mudstone and greyish-green,yellow-green silty mudstone of Lower Cretaceous Guyang Formation at Xiliannaobao Village,west Guyang County.According to the preservative conditions and lithological characters,it is purposed that there are parautochthonous burial and heterochthonous burial types in the study area,and the fossil plant should be under a warm humid subtropical climate during the Early Cretaceous.
