摘　　要：文章根据近年桂北地区 1∶5万区域地质调查和专题研究成果 ,对泥盆纪末至早石炭世生物群作了较系统的总结 ,划分了若干可与区域乃至世界对比的生物 (组合 )带 :有孔虫 12个 ,珊瑚 11个 ,腕足类 6个 ,牙形刺 5个 ,菊石、介形类各 2个 ;According to data of 1∶50 000 regional geological survey of Northern Guangxi, the biota from the end of Devonian Period to early Carboniferous epoch was summarized, a lot of biozones was classified: there are 12 foram Zones, 11 Anthozoa Zones, 6 Brachiopoda Zones, 5 Conodont Zone, 2 ammonites Zones and 2 Ostracoda Zones, the suggestions for classification of chronostratigraphic is also proposed.
