Taxonomic list
• type locality of Pawnee Creek Fm.
apparently most or all of Galbreath's "certain" records are from a single locality in Weld Co. (see fig. 8); records of Tedford et al. 1987 are for "the type locality and correlated sites"; Woodburne 1996a indicates that Galbreath's quarry is the same as the F:AM Pawnee Quarry, which presumably yielded Tedford's material
overlain by Horse and Mastodon Quarry, and Pawnee Buttes fauna of Tedford et al. 1987 is from even higher channel fills; see also Fig. 7 of Woodburne 1996a
ash immediately below Pawnee Quarry dated at 14.8 Ma (Ar-Ar?): Woodburne 1996a
unit includes the Pawnee Buttes Ash
"probable" occurrences: "Amblycastor? sp." Tomarctus brevirostris - see Courthouse Buttes "Amphicyon" sinapius - presumably type of Matthew 1902c Proboscidea indet. Aphelops megalodus (sic) "Ustatochoerus? schrammi" - see Schultz and Falkenbach 1941: F:AM specimens from "N. of Pawnee Buttes" and "Pawnee Buttes area" Cranioceras pawniensis: type of Frick 1937 from "west of buttes, middle horizon"; also postcrania from "Quarry Hill"
record of cf. Hystricops sp. discussed by Voorhies 1990 is Galbreath's "? Amblycastor sp." of uncertain provenance

Cynelos sp.1 Jourdan 1862 bear-dog "Early Barstovian... Pawnee Buttes area, Weld Co."; presumably includes "Amphicyon ingens" of Tedford et al. 1987 from Eubanks because Amphicyon is omitted by Hunt
