Mammalia - Esthonychidae
? Trogosus cf. latidens (Marsh 1874)
described by Gazin 1953
Mammalia - Condylarthra - Hyopsodontidae
Hyopsodus browni Loomis 1905
    = Hyopsodus powellianus Cope 1884
Alroy 2002
Mammalia - Creodonta
Prolimnocyon antiquus Matthew and Granger 1915
Morlo and Gunnell 2003
"Its occurrence in the same locality as I. datzae..."
Iridodon datzae n. gen., n. sp. Morlo and Gunnell 2003
Morlo and Gunnell 2003
"UM locality SP-5, Sweetwater County, South Pass, Green River Basin, Wyoming; Wasatch Formation, Cathedral Bluffs Tongue, Gardnerbuttean, Bridgerian biochron Br-1a."
Mammalia - Viverravidae
Viverravus lutosus Gazin 1952
Didymictis altidens Cope 1880
Mammalia - Perissodactyla
Hyracotherium cf. craspedotum Cope 1880
    = Perissodactyla indet. Owen 1848
Alroy 2002
could be Systemodon tapirinus
Mammalia - Perissodactyla - Palaeotheriidae
Hyracotherium vasacciense (Cope 1872)
Mammalia - Perissodactyla - Brontotheriidae
cf. Palaeosyops fontinalis Cope 1873
confirmed by Gunnell and Yarborough 2000; said to be "P. huerfanensis" by Stucky 1984c; I assume he refers to Gazin's Cathedral Bluffs locality because there are no brontotheres at the Green locality
