Machaeroidinae ("dagger-like") is an extinct subfamily of carnivorous sabre-toothed placental mammals from extinct family Oxyaenidae, that lived from the early to middle Eocene of Asia and North America.[3] Traditionally classified as hyaenodonts, this group is now classified as a member of the family Oxyaenidae.[4][5][6]
