Taxonomic list

• Galbreath treated the AMNH Horse and Mastodon Quarry as a possible equivalent of this fauna, but his "certain" records are entirely based on U of K specimens from Logan Co.; in fact, it is in Ogallala beds overlying the Pawnee Creek Fm. sensu stricto: Woodburne 1996a
underlies Vim-Peetz and equivalent to Pawnee Buttes; all three placed at the same level because the relationship of Pawnee Buttes to the others is unclear
"probable" occurrences: Ceratogaulus rhinocerus - presumably type of Matthew 1902d Euoplocyon sp. - not discussed by Wang et al. 1999 Amphicyon reinheimeri Cynarctus saxatilis - presumably type of Matthew 1902c from "Loup Fork (Pawnee Creek beds) of Cedar Creek" (see also Wang et al. 1999) Hypohippus osborni Alticamelus leptocolon Dromomeryx pawniensis "Meryceros warreni" "Meryceros minor"
