Mammalia - Carnivora - Mustelidae

	Brachypsalis sp. Cope 1890
	= Mustelidae indet. Fischer 1817	Alroy 2002
Mammalia - Carnivora - Amphicyonidae

	Amphicyon cf. frendens Matthew 1924
Mammalia - Carnivora - Canidae

	Tomarctus rurestris (Condon 1896)
	= Tephrocyon rurestris Condon 1896	Alroy 2002

	Merychippus brevidontus Bode 1935

	Merychippus seversus (Cope 1878)
	= Acritohippus isonesus Cope 1889	Alroy 2002
	this is following diagnosis of Downs 1956, which applies to A. isonesus according to Hulbert and MacFadden 1991; i.d. seems OK based on large size of specimen, general agreement with type as illustrated by Osborn 1918; JA pers. obs. 5.6.94
Mammalia - Perissodactyla - Rhinocerotidae

	Aphelops sp. Owen 1845
	specimen is from UO 2493, see comment above

Mammalia - Palaeomerycidae

	Rakomeryx americanus (Douglass 1899)
	(5 measurements)
	= Bouromeryx cf. americanus Douglass 1899	Alroy 2002

	Meterix cf. latidens Hall 1929
	= Plesiosorex cf. donroosai Green 1977	Alroy 2002
	"probably" P. donroosai, Voorhies 1983; material at Quartz and Red Basins is the same, Shotwell 1968, so Voorhies' comment applies to both
Mammalia - Erinaceidae
