Abstract

Formations of Lower and Middle Devonian age in eastern and central Nevada, and in central and western Utah were studied and sampled at many localities. Significant conodont faunas were obtained from all formations sampled except the Sevy and Lone Mountain Dolomites. Age relationships interpreted from the faunal discoveries suggest that definite time lines can be projected from central Utah to central Nevada for part of the Paleozoic rocks and that these time lines cut across most of the formations.
