摘      要：This discovery of complete body fossils of Halkieria and Microdictyon, two problematical taxa originally erected on the basis of isolated sclerites from Cambrian konservt lagersttte, sheds new light on our understanding of the Early Cambrian small shelly fauna. Based on comparisions of the morphology and preservation of nail shaped sclerites of zhijinitids, Hallucigenia and Onychodictyon, we propose that Zhijinites and Parazhijinites may have been closely related to tardipolypods, a diverse group of Early Cambrian metazoans.
