Taxonomic list

• as exposed only in the White River Valley in Dawes Co.; includes multiple localities and is close to the base of the group including the Gering Fm. at Wagner Quarry
Wagner Quarry is not the same as UNSM Dw-108
based on Tedford et al. 1996, it seems likely that most or all of the large mammals are not from UNSM Dw-108 but that all reported small mammals are; hence, I have separated the lists
"Heliscomys woodi" is from UNSM Dw-121 according to Tedford et al. 1996
