초록

Five species of graptolites were discovered from the Jigunsan Shale of Taebaeg area, Korea. They are herein described as Archiclimacograptus riddellensis (Harris, 1924), Pseudamplexograptus distichus(Eichwald, 1840), Hustedograptus teretiusculus(Hisinger) sensu Jaanusson, 1960, Hustedograptus vikarbyensis (Jaanusson, 1960), and Hustedograptus sp. The graptolite assemblage from the Jigunsan Shale corresponds to those of the Pseudamplexograptus distichus zone in the Baltic and German areas and the geologic age of graptolites bearing beds of the Jigunsan Shale might be late Middle Llanvirn.
