摘　　要：通过对栖霞地区蓬莱群进行详细的生物地层工作，除采集到大量微古植物化石外，未发现任何无脊椎动物化石。因此，前人在该区蓬莱群中采到的所谓“腕足类”和“双壳类”化石应予否定。本文重新肯定了栖霞地区蓬莱群的时代属震旦纪．Through the detailed biostratigraphic study of the Penglai Group in Qixia Region,plenty of micropaleobotanic fossils were collected, but no invertebrate fossils. Therefore, the so called “brachiopoda”and“bivalve”fossils previously sampled in the Penglai Group in this region are highly doubtful. In this peper,the authors reaffirmed that the age of the Penglai Group in Qixia region belongs to the Sinian Period.
