Collection methods and comments
Taxonomic list comments:sec 24 T 25N R 102 W
the "Tipton Tongue" collection of McGrew and Roehler 1960 reported by Grande is the same as the "Parnell Creek locality" of Roehler 1991a; however, "Hyracotherium sp." from this "locality" is from a lower level than the specimens from the Farson Sandstone Mbr. of Roehler, which seems to equal the "Wilkins Peak" collection; I assume that the latter is really from the Farson Sandstone
Mauger 1977 gives two "Class 1" reliability K-Ar dates for Tuff 3 of this member at separate localities; although they are mutually compatible, the member is quite thick (Roehler 1992) and the faunal locality is quite distant from either of the dated localities
