Parapternodus sp. Bown and Schankler 1982 placental "teeth belong to a species different from Parapternodus antiquus. They might represent a new species, or could belong to the early Wasatchian parapternodontid Koniaryctes paulus Robinson and Kron, 1998, which was described from the Powder River Basin."

Leptacodon sp., Leptacodon donkroni, Plagioctenoides sp., Plagioctenoides tombowni, Plagioctenoides microlestes
Plagioctenoides sp. Bown 1979 placental "Several isolated teeth and fragmentary jaws are of appropriate size and morphology to belong to Plagioctenoides and must represent either P. microlestes or P. tombowni, but in the absence of direct association with P4 they cannot be confidently assigned to species until differences between P. microlestes and P. tombowni are better understood."
