Eobasileus cornutus Cope 1872 uintathere | |
Notharctus robustior Leidy 1872 primate | |
Protoptychus hatcheri Scott 1895 rodent includes type of "P. smithi" of Wilson 1937c; see Turnbull 1991
| |
"Leptotomus leptodus" = Paramys leptodus
"Leptotomus leptodus" = Paramys leptodus Cope 1873 rodent listed by Black and Sutton 1984 as "L. leptos" - surely a lapsus; "L. grangeri" also listed despite synonymy of Wood 1962

Harpagolestes sp. Wortman 1901 condylarth | |
Limnocyon potens n. sp.3
| |
Metarhinus sp., "Dolichorhinus hyognathus n. sp." = Sphenocoelus hyognathus5, Sphenocoelus uintensis5
Metarhinus sp. Osborn 1908 brontothere presumably "M. earlei" type of Osborn 1908 from "North side of Haystack Mountain... Washakie B" (also listed by Roehler 1973); includes large bone bed sample from bed 643
"Dolichorhinus hyognathus n. sp." = Sphenocoelus hyognathus5 Osborn 1889 brontothere listed as "D. hyognathus" by Roehler 1973

Dilophodon minusculus Scott 1883 tapir if this includes the type, then the type of Chasmotherium intermedius may also be from this horizon: see Radinsky 1963; new material is from "approximately bed 630": McCarroll et al. 1996a

| |
Triplopus implicatus n. sp. Cope 1873 odd-toed ungulate as well as type of "Eotrigonias petersoni": see Radinsky 1967a
Triplopus cubitalis n. sp.2 Cope 1880 odd-toed ungulate is probably from this level see Radinsky 1967a; also at bed 630: McCarroll et al. 1996a
| |
Hyrachyus eximius Leidy 1871 odd-toed ungulate | |
Uintaceras radinskyi4 Holbrook and Lucas 1997 rhinoceros UCMP V-78102, V-5426, implicitly at this level; "Forstercooperia grandis"
| |
Amynodon advenus Marsh 1875 odd-toed ungulate "approximately bed 630"; presumably includes type of "Orthocynodon antiquus"; see Wilson and Schiebout 1981
