Taxonomic list

• preliminary list given by Matthew and Stirton 1930a
in a normal zone; based on FT zircon date of 6.8 +/- 0.2 Ma this should be C & K 92 zone C3Bn (old C6N), NOT old upper zone C5N, contra MacFadden et al. 1979; FT date also is supported by correlation by Perkins 1998 of this ash with the Blacktail Creek ash bed, dated at 6.7 +/- 0.10 Ma in Idaho by K-Ar; this correlation is confirmed by Passey et al. 2002, who report a revised Ar/Ar date of 6.62 Ma for the Idaho ash
NISP 3259: Shotwell 1958a; this probably excludes more recent collections of Dalquest
record of "Perognathus sp." is erroneous: Dalquest and Patrick 1989; they repeat the record in their list but argue against the i.d. in the text (!)
