Abstract The paper reports a new section of the Lower Silurian Fentou Formation which has been measured in Tiejishan Hill.This well-exposed section situates in the southeast of Wuhan，Hubei Province，just five kilometers from the downtown of Wuhan.Abundant fossils have been collected from this site，they were identified as 13 genera with 17 species in total，including trilobites，brachiopods，bivalves，gastropods，rostroconcha and piscis.Some of the species such as Coronocephalus wuningensis，C.gaoluoensis，Kailia intersulcata，Latiproetus sp.，Striispirifer shiqianensis，Striispirifer disparatus，Howellella sp.，Nucleospira calypta are common in the Fentou Formation of Jiangsu and Anhui Provinces，the Shamao Formation of west of Hubei Province and the Xiushan Formation in southwest China; Technophorus peregriuns has been reported from the upper part of the Xiushan Formation in Guizhou Province before，and also from both of the Wangjiawan Formation and Ningqiang Formation of Shaanxi Province.Orthonota perlata occurs frequently in the Fentou Formation in the Lower Yangtze River region.Based on biostratigraphic correlation，fossil assemblage from the Fentou Formation in Wuhan area belongs to the Early Silurian(Telychian，Llandovery). The lower part of the Fentou Formation might be deposited in a foreshore setting with a high energy，and the middle-upper part of this formation might be formed in an inshore and offshore setting with a lower energy.At last, the authors propose to cancel the stratigraphic unit of the Guodingshan Fomation in Wuhan area.
