一、前言 安徽贵池高坦寒武系出露于下扬子地区的南缘。生物区属于扬子生物区。以往,在安徽境内沿长江南岸,尚未见有这一生物区的动物群的有关报导。这一地区的泾县北贡、青阳青坑、石台丁香,都属于过渡型动物群。因此,高坦寒武系的发现,对确定本区扬子生物区的存在和位置都是有意义的。 I. Introduction The high Cambrian of Guichi, Anhui Province is exposed in the southern margin of the lower Yangtze region. The biological zone belongs to the Yangtze biological zone. In the past, no reports of fauna in this biological area have been reported in Anhui Province along the south bank of the Yangtze River. Jingxing County in this area Beigong, Qingyang green pit, Shitai clove, are transitional fauna. Therefore, the discovery of the high Cambrian is meaningful for determining the existence and location of the Yangtze biological zone in this area.
