摘　　要：对湖北武汉阳逻采集的 500余件化石木标本进行了 20余年的研究。在大量第一手研究材料的基础上, 已鉴定出化石木 12科 13属 20种, 其中被子植物 9科 9属 15种, 填补了我国新生代被子植物化石木群研究的空白。通过实地调查、室内制片、对比等研究方法, 推断出武汉阳逻被子植物化石木群与古砾石层的地质时代属新生代新近纪。The angiospermous fossil wood group in Yangluo is the first discovered in China, which was in the paleogravel bed of Xinzhou fault basin, at the south foot of Dabie Mountain. Since 1984, the authors have collected more than 500 pieces of fossil wood, categorized to 12 families, 13 genuses and 20 species. The achievement not only fills out the blank in the research of fossil wood in the Neogene in China, but also contributes plenty of data to the world's plants research. Based on the research of the fossil wood specimens, the authors propose that the geological age of the angiospermous fossil wood group and the paleogravel bed in Yangluo is Neogene of Cenozoic.
