Abstract: Some new material of Polybranchiaspiformes and Acanthodii was collected from Fentou Formation of Anhui and Jiangsu provinces. Based on the study of agnathans — gnathostomes including Hanyangaspis and Sinacanthus and so on, the Fentou Formation is considered as Llandovery in age. This view has been proved also by the newly discovered invertebrate fossils. Maoshan Formation was correlated with the upper part of Xiushan Formation in the past. Recently, the Xiushan Formation and Xiaoxiyu Formaüon was put in to the Lower Silurian by invertebrate workers. Because the Maoshan and Fentou formaüons are usually condnuous and conformably contacted, the Fentou Formaüon may correspond to Llandovery and Maoshan Formation to Wenlock.
