Creodonta

They were considerably more widespread and successful than the oxyaenids, the other clade historically considered part of Creodonta.
Two distinct families were historically thought to compose the order: Oxyaenidae and Hyaenodontidae.

Hyaenodonta

hyaenodonthyaenodontshyaenodontid
Hyaenodontidae ("hyena teeth") is a family of extinct predatory mammals, and is the type family of the extinct mammalian order Hyaenodonta.

Apterodon

Apterodon langebadreaeApterodon rauenbergensis
At least one hyaenodontid lineage, Apterodontinae, was specialised for aquatic, otter-like habits.
Apterodon is an extinct genus of hyaenodontid mammal that lived from the mid Eocene through the Oligocene epoch.

Megistotherium

Only four genera, Megistotherium, its sister genera Hyainailouros and Dissopsalis, and the youngest species of Hyaenodon, H. weilini, survived into the Miocene, of which, only Dissopsalis survived long enough to go extinct at the close of the Miocene.
Megistotherium (from Greek, megistos "greatest" + therion "beast" and osteon 'bone' + thlaston 'crushed, bruised' with -es being an agent noun: 'bone-crusher') is an extinct genus of hyaenodontid, the only known species of which is Megistotherium osteothlastes.

Oxyaenidae

oxyaenidoxyaenids
They were considerably more widespread and successful than the oxyaenids, the other clade historically considered part of Creodonta.
Anatomically, characteristic features include a short, broad skull, deep jaws, and teeth designed for crushing rather than shearing, as in the hyaenodonts or modern cats.(Lambert, 163)

Hyaenodon

Hyaenodon cruciansHyaenodon horridusHyaenodon vetus
Only four genera, Megistotherium, its sister genera Hyainailouros and Dissopsalis, and the youngest species of Hyaenodon, H. weilini, survived into the Miocene, of which, only Dissopsalis survived long enough to go extinct at the close of the Miocene. While Hyaenodon gigas, the largest Hyaenodon species, was as much as 1.4 m high at the shoulder, 10 feet long and weighed about 500 kg, most were in the 5–15 kg range, equivalent to a mid-sized dog.
Hyaenodon ("hyena-tooth") is the type genus of the Hyaenodontidae, a family of extinct carnivorous fossil mammals from Eurasia, North America, and Africa, with species existing temporally from the Eocene until the middle Miocene, existing for about.

Carnassial

The carnassials in a hyaenodontid are generally the second upper and third lower molars.
Among the hyaenodontids it is M2 and m3.

Dissopsalis

Dissopsalis is a genus of extinct predatory mammals of the family Hyaenodontidae.
