Carnivoramorpha ("carnivoran-like forms") is a clade of placental mammals of clade Pan-Carnivora from mirorder Ferae, that includes the modern order Carnivora and its extinct stem-relatives.[4][5]

General characteristics

[edit]

The common feature for members of this clade is the presence of the carnassial teeth. The carnassial teeth of the Carnivoramorpha are upper premolar P4 and lower molar m1.[6]

Classification and phylogeny

[edit]

Traditional classification

[edit]

Revised classification

[edit]

Recent phylogenetic studies indicate that the superfamily Miacoidea and family Miacidae are paraphyletic, with "miacids" being more closely related to carnivorans than to viverravids. In 2010 Flynn, Finarelli & Spaulding named a new clade Carnivoraformes within Carnivoramorpha, containing carnivorans and "miacids" but not viverravids.[7] The authors defined Carnivoraformes as the clade containing Carnivora and all taxa that are more closely related to Carnivora (represented by Canis lupus) than to viverravids (represented by Viverravus gracilis).
