Hyaenodontidae Explained

Hyaenodontidae ("hyena teeth") is an extinct family of placental mammals from extinct superfamily Hyaenodontoidea within extinct order Hyaenodonta. Hyaenodontids arose during the early Eocene and persisted well into the early Miocene. Fossils of this group have been found in Asia, North America and Europe.^{[1] [2] [3]}
