New macrofossils and their fossiliferous horizons, such as Chuarid from Qiaotou F., worms and U-shaped cylindrical mega-acritarches from Changlingzi F., worms (Pararenicola-Protoa-renicola-Huaiyuanella)-Tawuid from Nanguanling F., Medusa-like fossils from Xingmincun F., and Chuarid-Tawuid from Guotun F. etc, were found recently in southern Liaoning. In addition to the previously found Chuarid-Tawuid from Diaoyutai F. and Nanfen F., it makes the macrofossil successions perfect. But the late Precambrian in this area can be inferred to be A separate Liaonan System (Cao et al., 1982), which is lower than late Precambrian tillites and between the Sinian and Qingbaikou systems in stratigraphic column.According to the macrofossil assemblage from Nanguanling F. similar to that from Jiuli-qiao F., both these formations may be isochronal. Thereof, the reliable correlation of the late Precambrian formation in southern Liaoning with that in Huainan area is strengthened. The newly established Zhaojiakanzi stratigraphic section, near Shashan Village of Xietun Country and re-defined well-known Wuhangshan Section proved that the earlier stratigraphic classification by the previous geologists for many years is correct, stratigraphic classification of both these late Precambrian deposits can be unified, as their evolutionary geological history is basically similar.
