Temporal range: Late Eocene–Oligocene
Schultz and Falkenbach, 1956
Miniochoerus was named by Schultz and Falkenbach (1956). Its type is Miniochoerus battlecreekensis. It was synonymized subjectively with Oreonetes by Lander (1998). It was assigned to Merycoidodontidae by Schultz and Falkenbach (1956) and Stevens and Stevens (1996).
- M. affinis (syn. Merycoidodon platycephalus, M. battlecreekensis, Oreodon coloradoensis, Stenopsochoerus sternbergi)
- M. chadronensis (syn. Parastenopsochoerus conversensis, Stenopsochoerus douglasensis, S. reideri)
- M. forsythae
- M. gracilis
- M. starkensis (syn. M. cheyennensis, M. helprini, M. nicholsae, M. ottensi, Platyochoerus hatcreekensis, P. heartensis, Stenopsochoerus berardae, S. joderensis)
Typically, there were about the size of a small dog. Their skulls were small and short, compared to other oreodont species, many of which had proportionately large heads. Unlike other oreodont species, they had small canines which would have done little good against foes. The genus arose during the late Eocene, and survived the Late Eocene extinction event, giving rise to a dwarfed lineage during the early Oligocene.
