Hyaenodonta

Hyaenodonta ("hyena teeth") is an extinct order of hypercarnivorous eutherian mammals,[3] originally classified along with the oxyaenids as part of Creodonta.[4] Hyaenodonts may have evolved in Africa in the Paleocene.[5]

Scientific classification
Kingdom: Animalia

Subgroups
[see classification]
Synonyms
  • Hyaenodontida (Leidy, 1869)[2]

Hyaenodonts differed from Carnivora in that they replaced their deciduous dentition slower in development than carnivorans.[6]
