Genera

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.

History and naming

The genus Teratodon was named in 1965.

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".
