See text 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 7 million years.

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.
