Taxonomic list
Amphibia - Temnospondyli
Anura indet. (Fischer von Waldheim 1813)
Gardner and DeMar 2013
Mammalia - Multituberculata
Viridomys sp. Fox 1971
said to be new; if correct, this is the only post-Aquilan record of the genus (!)
Mammalia - Multituberculata - Cimolodontidae
Cimolodon sp. Marsh 1889
Standhardt 1994
said to be new; if correct, this is the only Cenozoic record of the genus
Mammalia - Multituberculata - Neoplagiaulacidae
Mesodma thompsoni Clemens 1964
Mammalia - Multituberculata - Ptilodontidae
Ptilodus sp. Cope 1881
said to be new
Mammalia - Periptychidae
Carsioptychus coarctatus (Cope 1883)
    = Periptychus sp. Cope 1881

Haploconus inopinatus Gazin 1939
    = Haploconus angustus Cope 1881
Alroy 2002
Mammalia - Procreodi - Arctocyonidae
Baioconodon sp. Gazin 1941
Standhardt 1994
presumably includes "Eoconodon sp." as no other taxa in the original list are omitted; this guess is seconded by Williamson 1996
Mammalia - Viverravidae
Bryanictis sp. MacIntyre 1966
spelled with current rank as Protictis (Bryanictis)
"Protictus (sic) (Bryanictis) sp." said to be new; listed as "Protictis" by Williamson 1996, who compares it to both Bryanictis and Simpsonictis
Mammalia - Condylarthra - Hyopsodontidae
Ellipsodon priscus Matthew 1937
    = cf. Bomburia sp. Van Valen 1978
Williamson 1996
replaced by Bomburodon
cf. Protoselene sp. Matthew 1897
Williamson 1996
mioclaenid, said to be new
Mammalia - Insectivora
Insectivora indet. Bowdich 1821
Mammalia - Cimolestidae
Gelastops sp. Simpson 1935
Mammalia - Groeberida - Nototheriidae
