Tytthaena ("little hyena") is an extinct genus of placental mammals from extinct subfamily Tytthaeninae within extinct family Oxyaenidae, that lived in North America from the late Paleocene to early Eocene.[1]
Description
Tytthaena is the smallest oxyaenid known. Morphologically, it resembles Oxyaena. It can be distinguished from other oxyaenids by its size and dentition. Its molars were narrow, with elongate talonids.[2][4]
