Stratigraphic range: Middle and Upper Cambrian; Devonian
Kinds of fossils: Trilobites, brachiopods, miscellaneous other
Quadrangle or area: Eagle Quad.
Shipment No.: A-61-16
Referred by: Brabb, Earl E.
Report prepared by: Palmer, A. R.
Date: 11/06/1961

This report concerns 10 collections of trilobites and other fossils, mostly from Cambrian rocks. The 9 Cambrian collections will be dealt with in groups related to the collection localities in the vicinity of Chief Mtn. and Crow triangulation station. The one Devonian collection is only briefly mentioned as it contains an ostracod fauna that should be more definitive than the trilobites and has been turned over to Jean Berdan for further comment.
