Miniochoerus is an extinct genus of small oreodont endemic to North America. They lived during the Late Eocene to Early Oligocene 38–30.8 mya, existing for approximately. Fossils have been found only in North Dakota, South Dakota, Nebraska, Montana, and Wyoming.

Species

Description

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.
