Pan-Carnivora ("all carnivorans") is a clade of mammals from mirorder Ferae, consisting of the clade Carnivoramorpha, extinct orders Hyaenodonta and Oxyaenodonta, and extinct genera Altacreodus and Tinerhodon.

Anatomy

Comparison of carnassial teeth of wolf and typical hyaenodontid and oxyaenid

The common feature for members of this clade is the presence of the carnassial teeth. This feature allows distinguishing the Carnivoramorpha, Oxyaenodonta and Hyaenodonta from the other carnivorous placental mammals.[2] However, these mammals are distinguished between them self based on the position of the carnassial teeth and the number of molars. The carnassial teeth of the Carnivoramorpha are located in P4 and m1, in Oxyaenodonta are M1 and m2, and in Hyaenodonta are M2 and m3. This appears to be a case of a possible evolutionary convergent adaptation toward similar diet.
