There are 25 genera and 47 species of conodont , 4 genera and 6 species of coral and some foraminifera . ch . 4 biostratigraphical regions based on the study on the conodont , coral and foraminifera fossils in research area , it was discovered that the biota features are resemble to the south china . so a conclusion can be drawn that the research area and south china belong to the same biogeographical region 生物地层分区本文通过对牙形刺、蜒类、珊瑚等化石的对比研究,发现研究区的生物群特征与华南区生物群相近,这表明在该区早、晚石炭世与华南区及东古特提斯区同属一个生物地理区系。
