Paleontologic evidence recently collected by the writers indicates that certain Cambrian rock units in the Silver Island Mountains (Fig. 1) are of different age than previously reported. If previous age interpretations are used, anomalies result when maps of regional lithofacies are compiled for the Great Basin region, and when a reconstruction of geologic history is attempted. The purposes of this note are to review these previous age interpretations, to present evidence for alternative age designations, and to propose a revision of stratigraphic terminology.

Cambrian stratigraphy in the Silver Island Mountains has been discussed by Bentley (1958), Schaeffer...
