Taxonomic list
• "Copemys russelli assemblage zone"
see section F in Fig. 2; this is the highest reported collection in the Rodent Hill Basin section
according to MacFadden et al. 1990, the Lapilli Sandstone in the uppermost Hell Gate Basin section may correlate with the uppermost Rodent Hill Basin section, and a tuff in this unit is dated at 13.4 +/- 0.2 Ma (KA); however, the exact correlation is not indicated and the dated tuff itself apparently is not present in the latter section
