Stratigraphic range: Permian
Kinds of fossils: Brachiopods
Quadrangle or area: Charley River and Eagle quads., Alaska
Shipment No.: A-83-37
Referred by: Blodgett, Robert B. , Barnes, T. J.
Report prepared by: Dutro, J. Thomas, Jr.
Date: 12/05/1983

This report covers 9 collections from the Permian rocks of east-central Alaska. They all appear to represent the Takhandit Formation and most contain elements of the brachiopod assemblage described by Grant (in Brabb and Grant, 1971). One collection (field no. 83-YK-208-DJD), not listed in the submittal letter, contains only indeterminate echinodermal debris. This collection, together with 83-YK-726-WJG and 83-YK-207-DJD, probably represent the sandstone unit of the Tahkandit.
We would appreciate maps showing precise localities for these collections.
