Taxonomic list
underlies Black Peaks localities of Schiebout 1974
said to be late Puercan, but reassigned to the Torrejonian by Williamson 1996

Viridomys sp. Fox 1971 multituberculate said to be new; if correct, this is the only post-Aquilan record of the genus (!)

Cimolodon sp.3 Marsh 1889 multituberculate said to be new; if correct, this is the only Cenozoic record of the genus

"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
| |
|
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
