Teratodontidae
Teratodontinae ("monstrous teeth") is a subfamily of extinct hyaenodonts. Fossil remains of these mammals are known from Middle Eocene to Late Miocene deposits in Africa, the Arabian Peninsula, and Asia.[1]

History and naming
The genus Teratodon was named in 1965.[2]
The name of the subfamily translates as "monstrous teeth" (from Ancient Greek τέρας (téras) 'monster', from Ancient Greek ὀδών (odon) 'tooth' and taxonomic suffix "-inae".
