Carnivoramorpha is a clade of placental mammals. In line with its definition introduced in 1993, Carnivoramorpha includes all Pan-Carnivora except creodonts. In other words, it includes the order Carnivora sensu stricto (i. e. the crown Carnivora) and its extinct stem-relatives except creodonts.[4][5] The clade corresponding to all Carnivoramorpha except Viverravidae has been called Carnivoraformes since 2010.[6]

In the second half of the 20th century, the clade now called Carnivoramorpha was simply called Carnivora and it is often still called Carnivora today[7][8][9][3][4]. Note that the name Carnivora can refer to at least three different taxa in the literature - (1) the crown Carnivora (also known as Neocarnivora), (2) Carnivoramorpha (i. e. the topic of this article), or (3) Pan-Carnivora.

General characteristics

[edit]

The common feature for members of the clade Carnivoramorpha is the presence of the carnassial teeth. The carnassial teeth of the Carnivoramorpha are upper premolar P4 and lower molar m1.[10]

Classification and phylogeny

[edit]

Previous use of the name Carnivoramorpha

[edit]

The name Carnivoramorpha was introduced in 1979 by A. A. Gureyev and was then used primarily by Soviet authors as a taxon (originally superorder) comprising what is today called Pan-Carnivora plus Insectivora (or Lipotyphla, in later texts).[1][11]

Classification around the year 2000

[edit]

In 1993, Wyss & Flynn introduced a new, much narrower definition of Carnivoramorpha - they understood Carnivoramorpha as comprising the crown Carnivora + all basal clades to crown Carnivora, but without Creodonta.

Revised classification

[edit]

Recent phylogenetic studies indicate that the superfamily Miacoidea and family Miacidae are paraphyletic, with "miacids" being more closely related to crown carnivorans than to viverravids. In 2010 Flynn, Finarelli & Spaulding named a new clade Carnivoraformes within Carnivoramorpha, containing crown carnivorans and "miacids" but not viverravids.[6] The authors defined Carnivoraformes as the clade containing crown Carnivora and all taxa that are more closely related to crown Carnivora (represented by Canis lupus) than to viverravids (represented by Viverravus gracilis).
