Dissopsalis is a genus of teratodontine hyaenodonts of the tribe Dissopsalini. The older species, D. pyroclasticus, lived in Kenya during the middle Miocene, while the type species, D. carnifex, lived in Pakistan and India during the middle to late Miocene.

Hyainailouros ("hyena-cat") is an extinct polyphyletic genus of hyainailourid hyaenodont mammal of the polyphyletic tribe Hyainailourini within paraphyletic subfamily Hyainailourinae, that lived during the early to middle Miocene, of which there were at least three species spread across Europe, Africa, and Asia.
Sivapterodon is an extinct genus of hyainailourid hyaenodont mammal of the polyphyletic tribe Hyainailourini within paraphyletic subfamily Hyainailourinae that lived in Pakistan during the middle Miocene.
Lahimia ("carnivore") is an extinct genus of placental mammals from extinct family Boualitomidae within extinct order Hyaenodonta, known from the middle Paleocene of Morocco. Lahimia selloumi is the one of the oldest known members of order Hyaenodonta.
Hyaenodonta is an extinct order of hypercarnivorous placental mammals of clade Pan-Carnivora from mirorder Ferae. Hyaenodonts were important mammalian predators that arose during the early Paleocene in Europe and persisted well into the late Miocene.
Hyainailouridae ("hyena-cats") is a paraphyletic family of extinct predatory mammals from extinct paraphyletic superfamily Hyainailouroidea within extinct order Hyaenodonta. Hyaenodontids arose during the middle Eocene and persisted well into the middle Miocene. Fossils of this group have been found in Asia, Africa, North America and Europe.
Isohyaenodon is an extinct polyphyletic genus of hyainailourid hyaenodont mammal from polyphyletic subtribe Isohyaenodontina. Remains are known from early to middle Miocene deposits in Kenya, East Africa.
Exiguodon is an extinct genus of hyainailourid hyaenodont mammal of the polyphyletic tribe Hyainailourini within paraphyletic subfamily Hyainailourinae. Remains are known from early Miocene deposits in Kenya and Uganda, in East Africa.
Falcatodon is an extinct genus of hyainailourid hyaenodonts of the polyphyletic tribe Hyainailourini within paraphyletic subfamily Hyainailourinae, from the Early Oligocene (Rupelian) of the Faiyum Oasis depression in Egypt.
Metapterodon is an extinct genus of hyainailourid hyaenodonts of the tribe Metapterodontini withnin paraphyletic subfamily Hyainailourinae, that lived in Africa during the early Oligocene to early Miocene. Fossils of Metapterodon were recovered from the Egypt, Uganda, Elisabeth Bay Formation in Namibia, and Rusinga Island and Karungu in Kenya.
Sectisodon is an extinct genus of hyainailourid hyaenodont mammal of the polyphyletic tribe Hyainailourini within paraphyletic subfamily Hyainailourinae from early Oligocene to early Miocene deposits in Egypt and Uganda.
Metasinopa is a genus of teratodontine hyaenodont that lived during the early Oligocene in Egypt.
Orienspterodon is an extinct genus of hyainailourid hyaenodonts from paraphyletic subfamily Hyainailourinae that lived in China and Myanmar during the middle to late Eocene. Orienspterodon dahkoensis was originally assigned to genus Pterodon in 1975, but was eventually assigned to its own genus in 2007.
Ekweeconfractus is an extinct genus of teratodontine hyaenodont known from 17 million year old deposits at the Moruorot site in Kenya.
Hyainailouroidea ("hyena-cats") is a paraphyletic superfamily of extinct predatory mammals from extinct order Hyaenodonta. Fossil remains of these mammals are known from middle Eocene to late Miocene deposits in North America, Europe, Africa and Asia. Members of this group probably originate from Afro-Arabia, a continent that remained isolated from the Albian to the Miocene. While in North America and Eurasia hyaenodonts competed with other predatory mammals, in Afro-Arabia they remained the main terrestrial predators.
Hyainailourinae ("hyena-cats") is an extinct paraphyletic subfamily of hyainailourid hyaenodonts that lived in Africa, Asia, North America and Europe from the middle Eocene to middle Miocene. They appeared in Africa about 47.8 Ma ago and soon after spread as far as East Asia.
Hyainailourini ("hyena-cats") is an extinct polyphyletic tribe of hyainailourid hyaenodonts from paraphyletic subfamily Hyainailourinae that lived in Africa, Asia and Europe during the middle Eocene to middle Miocene.
Boualitomidae is a family of extinct predatory mammals from extinct order Hyaenodonta. Fossil remains of these mammals are known from middle Paleocene to late Eocene deposits in Africa. Boualitomids had only three pairs of premolars in the lower dentition, lacking the first one.
