Teratodontidae ("monstrous teeth") is a family of extinct predatory mammals within the polyphyletic superfamily Hyainailouroidea within extinct order Hyaenodonta. Fossil remains of these mammals are known from Middle Eocene to Late Miocene deposits in Africa and Asia.[2][3][4][5]

Etymology

The name of the family translates as "monstrous teeth" (from Ancient Greek τέρας (téras) 'monster', from Ancient Greek ὀδών (odon) 'tooth' and taxonomic suffix "-idae".
