| Abstract: | This paper mainly deals with several kinds of peculiar metazoan fossil remains, which were collected from the basal Cambrian phosphoric rock series of both Yangtze and Tarim platforms, China. They were artificially taken as helmet like fossils by their appearance, since they are usually low cone like with apex curved downward, and are somewhat similar to ancient helmets. Three genera and 4 species are described, including 1 new genus and 1 new species; and their distributions, preservation and affinities are briefly discussed. Based on their features, the authors deduce that they should represent outer hardparts of various metazoans. |
