Taxonomic list
descriptions of Robison 1986 do not incorporate the collections reported by Tomida and Butler and Tomida 1982
"Oxyclaenus pearcei" is not discussed by Robison 1986 and I assume it is only present at Wagonroad Upper Horizon
Haploconus "inopinatus" is not discussed by Robison 1986 and I assume it is only present at Wagonroad Upper Horizon

"Chriacus cf. baldwini" = Chriacus baldwini11, "Oxyclaenus pearcei n. sp." = Chriacus baldwini5, "Mimotricentes subtrigonus" = Tricentes subtrigonus11, "Mimotricentes elassus n. sp." = Tricentes subtrigonus5, "Protogonodon biatheles n. sp." = Loxolophus5, Loxolophus spiekeri11, Oxytomodon perissum n. gen. n. sp.5
"Chriacus cf. baldwini" = Chriacus baldwini11 Cope 1882 condylarth includes "C. truncatus" and additional "C. sp." of Robison 1986 according to Williamson 1996
"Mimotricentes subtrigonus" = Tricentes subtrigonus11 Cope 1881 condylarth probably also includes additional M. sp. of Robison 1986

Protoselene griphus11, Ellipsodon grangeri7, ? Ellipsodon sternbergi n. sp.4, Promioclaenus sp.7, Promioclaenus lemuroides7
Ellipsodon grangeri7 Wilson 1956 condylarth may include additional "? Ellipsodon sp." of Tomida and Butler 1980
Promioclaenus lemuroides7 Matthew 1897 condylarth according to Williamson 1996, this definitely includes "Ellipsodon shepherdi" type of Gazin 1939 and "Jepsenia mantiensis" type of Gazin 1939, and probably includes Robison's "Litaletes disjunctus"
