• said to be "high" in the Mbr., exact m level unknown
underlies Black Peaks localities of Schiebout 1974
said to be late Puercan, but reassigned to the Torrejonian by Williamson 1996
Amphibia
 Salientia -
Anura indet.2 Fischer von Waldheim 1813 frog
Mammalia
 Insectivora -
Insectivora indet. Bowdich 1821 insectivoran
 Procreodi - Arctocyonidae
Baioconodon sp.3 Gazin 1941 condylarth
presumably includes "Eoconodon sp." as no other taxa in the original list are omitted; this guess is seconded by Williamson 1996
 Theriamorpha - Viverravidae
"Bryanictis sp." = Protictis (Bryanictis)
"Bryanictis sp." = Protictis (Bryanictis) MacIntyre 1966 placental
"Protictus (sic) (Bryanictis) sp." said to be new; listed as "Protictis" by Williamson 1996, who compares it to both Bryanictis and Simpsonictis

Haploconus angustus1 Cope 1881 condylarth
Periptychus sp.4 Cope 1881 condylarth
 Condylarthra - Hyopsodontidae
cf. Protoselene sp.4, "cf. Bomburia sp." = Bomburodon4
cf. Protoselene sp.4 Matthew 1897 condylarth
mioclaenid, said to be new
"cf. Bomburia sp." = Bomburodon4 Williamson and Carr 2012 condylarth

? Peradectes sp.4 Matthew and Granger 1921 marsupial
 Multituberculata - Cimolodontidae
Cimolodon sp.3 Marsh 1889 multituberculate
said to be new; if correct, this is the only Cenozoic record of the genus
