"Platyochoerus platycephalus" Schultz and Falkenbach 1956; and type of "Stenopsochoerus sternbergi" Schultz and Falkenbach 1956: all implicitly "Zone A" and synonyms of M. affinis; M. ("Stenopsochoerus") chadronensis Schultz and Falkenbach 1956: implicitly "Zone A"; sample is apparently stratigraphically mixed because two species form a chronocline elsewhere

Brule Zone A; "Otionohyus wardi" Schultz and Falkenbach 1968: Brule Zone A
