while this name is not applied by Peterson, Honey and Izett 1988 use it to distinguish his fauna from theirs
type of "Bassariscops willistoni" is from 1 mi SW of Sunbeam, which is a different locality according to Honey and Izett 1988; referred specimen is actually Cynarctoides lemur: Wang et al. 1999
"Merycoidodontidae indet." Honey and Izett 1988: "Ticholeptus?" from Emma (Gilsonite) Mine "near the bluff of the White River canyon in Utah"
"camelid" presumably the "camelid closely allied to Stenomylus" that is actually an antilocaprine: Frick and Taylor 1968
presumed chalicothere is actually a "Teleodus" from the Duchesne River Fm. near Vernal, UT: Skinner 1968
