Quadrangle or area: Port Alexander D-1 quad., Alaska
Shipment No.: A-82-10
Referred by: Brew, David A.
Report prepared by: Dutro, J. Thomas, Jr.
Date: 03/10/1983

Three collections in this shipment were turned over to me for examination. Only one has diagnostic megafossils (USGS 28825-PC). This collection, from Muffler's Cl unit, contains a Pennyslvanian assemblage, corroborating the age based on the more diversified faunas of USGS 27714-PC (see report on A-80-17 dated 3/9/83). The collection from the silty limestone member of the Saginaw Bay Formation (USGS 28822-PC) may well be early Permian, but the single species present is not diagnostic. Conodont studies of other collections may produce definitive results for this sequence, however. Collections retained.
