• does not include Fitterer Bed Quarry (see)
probably includes most or all of Little Bad Lands list of Douglass 1909b and other Little Badlands records
H & L list several new records of unclear provenance
the following Orellan records from Hoganson and Lammers 1985 are of unclear status: cf. "Protosciurus" sp. cf. Paradjidaumo sp. cf. Heliscomys sp. Caenopus sp. cf. Hyracodon sp.
Orellan taxa listed by Kihm and Lammers 1986: ? Cedromus sp. ? Hoplophoneus sp. ? Eusmilus sp. ? Amphicyonidae indet. "Diceratherium" tridactylum Entelodontidae indet. ("Entelodon sp.") ? Hypertragulus sp. multiple oreodonts of Schultz and Falkenbach, e.g.
Orellan taxa listed by Lammers and Hoganson 1988: Hyaenodon crucians Hyaenodon horridus
supposed Whitneyan fauna of Kihm and Lammers 1986 is of unstated provenance and may correspond to "Upper White River" fauna of Douglass 1909b including rhinos, oreodonts, and "Mesohippus" Eumys brachyodus Kihm 1990 is from Schmidt Ranch, of uncertain stratigraphic relation to the other Stark Co. localities Palaeocastor nebrascensis Xu 1996: "AMNH Loc. 5 of Hough, Stark Co." "Brontotheriid" of Lammers and Hoganson from "Little Bad Lands" is of uncertain stratigraphic provenance
"Fitterer Ranch" no further data: Parictis sp. Hunt 1998a: "Fitterer Ranch, SW of Dickinson"
