Epoicotheriinae ("strange beasts") is an extinct paraphyletic subfamily of insectivorous placental mammals within extinct paraphyletic family Epoicotheriidae in extinct order Palaeanodonta, that lived in North America and Europe from the early Eocene to early Oligocene.^[2] Epoicotheriins were fossorial mammals. Late Eocene/early Oligocene genera were highly specialized animals that were convergent with the talpids, golden moles and marsupial mole in the structure of their skulls and forelimbs, and would have had a similar lifestyle as subterranean burrowers.^[3]
