February 21, 1979 Ms Carol Wagner Allison, University of Alaska Museum, University of Alaska, Fairbanks, Alaska 99701 Dear Ms. Allison, I have processed the limestone samples you recently sent me from locality A-1237, and they have a relatively diverse silicified gastropod fauna. A preliminary list of the snails present include: (see faunal list) The gastropods in themselves are not diagnostic of a specific age, but they would be consistent with a Middle Devonian assignment. I have sorted and hardened the specimens and will leave them with Bob Blodgett in case he comes up with any more specimens. Sincerely, David M. Rohr Assistant Professor |

Department of Geology, Oregon State University, Corvallis, Oregon 97331 May 18, 1979 Dr. Carol W. Allison University of Alaska Museum University of Alaska Fairbanks, Alaska 99701 Dear Dr. Allison: Here are the faunal lists of the brachiopod and associated biotic elements present in UA Mus. locs. A-1216, A-1217, A-1227, & A-1237. Conodont identifications by Gilbert Klapper have not yet been received. Sincerely yours, Robert B. Blodgett J.G. Johnson |

Comment: | Age: probably late Couvinian (late early Middle Devonian). The overall aspect of the fauna indicates a Middle Devonian age. However, the presence of Variatypa cf. arctica, indicates a late Couvinian age, as it is a widespread faunal element in western North American strata of that age, being reported from the Northwest Territories, Manitoba, Michigan and the Hudson Bay region. |
