The Precambrian trace fossils described in this paper were found in the Yunmengshan and Beidajian Formation of the Ruyang Group of Lushan and Ruyang, western Henan province. They include the following ichnotaxa: Ruyangichnus loyuensis ichnogen. et ichnosp. nov. , Tor-rowangea rosei Webby, Changchengia ichnosp. and Squamodictyon(?) ichnosp. and an uncertain ichnospecies. According to the data of isotopic ages, microfloras and stromatolites, the age of the Ruyang Group should be Middle Proterozoic, ranging from 1100 to 1400 Ma, so it may be correlated with the Middle Proterozoic Jixian System of the Jixian section. This paper also briefly discusses the significance of evolution of this trace fossil assemblage.
