Abstract: The first work on vertebrates from the Silurian Maoshan Formation of Changxing, northwestern Zhejiang was done by Pan (1986a) who described the galeaspid fish Sinogaleaspis zhejiangensis, as well as finspines of Sinacanthus. From the same locality and horizon, Wang (1991) described another two galeaspid species, Meishanaspis lehmani and Changxingaspis gui. Since 1998, the authors have organized three subsequent excursions to Changxing, and collected abundant Silurian fish remains, which are suggestive of the Sinogaleaspis-Xiushuiaspis Fauna, the fish fauna originally described from Xiushui, Jianxi Province (Pan and Wang, 1980). The present account describes the eugaleaspid remains, with a revision of previously described material, and discusses the phylogeny of the Eugaleaspiformes.
