Taxonomic list

• includes KU-MT-44 (Tavenner Ranch loc. 4) and probably several other localities: see Pierce and Rasmussen 1992
uncomformably overlies welded tuff dated at 29.5 +/- 2.8 Ma (FT on zircon), but uncomformity is shown to be considerable and error is large: Tedford et al. 1987
faunal lists of Douglass (1903) and Riel (1964) are stratigraphically mixed but most or all of the records correspond to Rasmussen i.d.s for the Lower Cabbage Patch, including: Meniscomys sp. "? Mesocyon drummondensis" - confirmed as included in Rasmussen list by Wang 1994 Kukusepasutanka schultzi - the type, from "Hellgate River, 3 miles east of Drummond Granite County": Macdonald 1956b Diceratherium cf. armatum "Promerycochoerus" minor type - from KU Mt-33, lower Cabbage Patch beds: Stevens and Stevens 1996 "Leptomeryx transmontanus" - type of Douglass 1903 is from "east of Drummond on Hellgate River": Frick 1937 "Desmatochoerus macrosynaphus" - type is from KU Mt-31, same level as Mt-33: Stevens and Stevens 1996
"? Parasminthus sp." is not documented in North America, see Korth 1994c
