| Abstract: | A layer of graptolites was discovered from the Upper Cambrian Kushan Formation at Lanjia of Liaoyang, Liaoning by the writer in the summer of 1986. They contain 2 genera and 5 species (including 2 new species and 1 new subspecies), namely, Dendrograptus liaoyangensis sp. nov., Dendrograptus liaoyangensis latus subsp. nov., Callograptus lanjiaensis sp. nov., Callograptus sp. A and Callograptus sp. B., which are found to be associated with the trilobite Drepanura premeenili. This graptolite-bearing layer might represent the lowest one ever known in China, providing these new data of great significance and available for making researches on the origin, evolution and expansion of the graptolites. |
