Reference
Title: Stratigraphic distribution of Permian corals in Alaska ,  1975
Information tabulated by major regions of Alaska is the result of a restudy of all available Permian rugose and tabulate corals from Alaska, completed in 1972. Most specimens were collected by members of the U.S. Geological Survey, beginning with corals collected by F.C. Schrader in 1902, but this list also includes collections of Permian corals made by the writer between 1963 and 1968. Almost half of the specimens studied required revised identifications at the generic level, primarily due to recent changes in taxonomy and classification. No attempt was made to identify specimens at the species level except for a comparatively few specimens which obviously were conspecific with described species and for species described by Rowett (1969). Stratigraphic and locality information provided by the original collectors also has been updated where possible by reference to more recent geologic studies and mapping in Alaska. Some stratigraphic and locality information nevertheless remains unclear. PC number refer to collections catalogued in the U.S. Geological Survey Permian-Carboniferous catalog: UA specimen numbers refer to specimens stored at the University of Alaska at College, Alaska.
