Taxonomic list
• rodents and lagomorph originally described by Wilson 1936
High Ridge, Mickey Wash, Mount Wilson, and Upper Petrified Canyon are also included in the "Smiths Valley Fauna"
biotite from tuff in beds dated at 9.3 (= 9.55) Ma by Evernden et al. 1964 (KA 485); beds assigned to Coal Valley Fm. and placed "on the north side of Wilson Canyon" by Gilbert and Reynolds 1973, which is near all the Smiths Valley localities except the Mickey Wash cluster
Gilbert and Reynolds 1973 report three further dates from the Coal Valley Fm., but they appear to be from Wichman Valley SE of Macdonald's localities, and their stratigraphic position is unclear in any case
not clear how any of the Smiths Valley localities other than the Mickey Wash cluster fit in to the sections of either Axelrod 1956 or Gilbert and Reynolds 1973, neither of which refers to Macdonald 1956
Tedford et al. 1987 list Barbourofelis fricki and Eomellivora sp. from "Smiths Valley"
