Taxonomic list
underlies Black Peaks localities of Schiebout 1974
said to be late Puercan, but reassigned to the Torrejonian by Williamson 1996
| Mammalia | |
|
Mesodma thompsoni Clemens 1964 multituberculate | |
|
| |
|
Cimolodon sp.3 Marsh 1889 multituberculate said to be new; if correct, this is the only Cenozoic record of the genus
| |
|
Viridomys sp. Fox 1971 multituberculate said to be new; if correct, this is the only post-Aquilan record of the genus (!)
| |
|
| |
|
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

"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
