Schultz and Falkenbach 1956
    = Miniochoerus sp. Schultz and Falkenbach 1956
Alroy 2002
"North of Node"; M. chadronensis "Stenopsochoerus douglasensis" Schultz and Falkenbach 1956: "North of Node, which includes "Northeast of Node" M. "battlecreekensis" according to Stevens and Stevens 1996; sample is apparently stratigraphically mixed because two species form a chronocline elsewhere
Stenopsochoerus douglasensis Schultz and Falkenbach 1956
Stevens et al. 2023
synonym of Miniochoerus chadronensis
