WILSON INTRODUCTION Angels Peak stands on the eastern rim of a large area of badlands carved by a tributary of the San Juan River from Paleocene strata of the Nacimiento formation, and presumably also from Wasatchian strata of the San José (Simpson, 1948). This area of badlands lies some twelve miles south of Bloomfield, New Mexico in the Kutz Canyon drainage. Angels Peak (Angel Peak of Granger, 1917) and Kutz Canyon (Coots Cañon of Granger, and of Matthew, 1937) are names that have been applied to the location (figure 1). [Illustration: FIGURE 1. Map of a part of the San Juan Basin, New Mexico, showing location of University of Kansas fossil locality west of Angels Peak.] E. D. Cope's collector, David Baldwin, possibly worked in this area in the Eighties. The first published record, however, of mammalian fossils from the Angels Peak badlands was made by Walter Granger in 1917 as a result of his field work in the preceding summer. Granger obtained specimens, usually poorly preserved, but occasionally rather abundant locally, from various levels up to within 150 feet of the western rim of the badlands basin. This collection was obviously of Torrejonian or middle Paleocene age. In the 1917 report, Granger gave as a faunal list the following species: _Tetraclaenodon_ _Mioclaenus turgidus_ _Periptychus rhabdodon_ _Anisonchus sectorius_ _Protogonodon sp. nov._ _Tricentes_ _Deltatherium_ _Psittacotherium_ To this list should be added _Triisodon antiquus_, a specimen of which is stated by Matthew to come from Kutz Canyon in his monograph (1937:80) on the Paleocene faunas of the San Juan Basin. In the summer of 1948, a field party from the University of Kansas was fortunate in finding a local concentration of rather well preserved material at the western edge of the badlands at Angels Peak. Because it probably will be some time before a full account of this faunule can be prepared, it is thought advisable, preliminarily, to give a general statement as to occurrence, and tentatively to list the species.
