Abstract
"The Powder river local fauna, collected mainly under the direction of H.E. Wood, II, is of earliest Wasatchian age, correlative with the Four Mile and early Gray Bull assemblages. The enclosing Eocene rocks are probably not referable to the Wasatch formation. Forty-one species of mammals are represented in the collection; comparative faunal lists of the Powder River and Four Mile local faunas are presented. A very primitive rodent is present at Powder River, as is a species of true Leptacodon and a probably new small pantolestine. Subspecific divisions are abandoned in the genera Paramys and Hyracotherium, but retained for Phenacolemur. The taxa Adapisoricidae, Phenacodontidae, Apheliscinae, Paeneprolimnocyon, Tetonius, Haplomylus, Hyopsodus miticulus, and Esthonyx spatularius are discussed in some detail"--P. 309.
