Paenemarmota barbouri Hibbard and Schultz 1948 squirrel seems OK because it is repeated by Miller and Carranza

"Equus simplicidens" = Plesippus simplicidens2 Cope 1892 horse "E. (Dolichohippus) sp." of Miller and Carranza 1984; probably also includes "Pliohippus cf. osborni," which was compared to Dinohippus mexicanus and Pliocene Equus; this is an old Stirton i.d. and I believe it is repeated incorrectly by Miller and Carranza 1984
