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]
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]
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 ).
Carnivora is an order of placental mammals that have specialized in primarily eating flesh, whose members are formally referred to as carnivorans. The order Carnivora is the fifth largest order of mammals, comprising at least 279 species.
Viverravidae is an extinct monophyletic family of mammals from extinct superfamily Viverravoidea within the clade Carnivoramorpha, that lived from the early Palaeocene to the late Eocene in North America, Europe and Asia. They were once thought to be the earliest carnivorans and ancestral to extant ones, but now are placed outside the order Carnivora based on cranial morphology as relatives to extant carnivorans.
Miacidae is a former paraphyletic family of extinct primitive placental mammals that lived in North America, Europe and Asia during the Paleocene and Eocene epochs, about 65–33.9 million years ago. These mammals were basal to order Carnivora, the crown-group within the Carnivoraformes.
Miacis is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Miacoidea is a former paraphyletic superfamily of extinct placental mammals that lived during the Paleocene and Eocene epochs, about 66-33,9 million years ago. This group had been traditionally divided into two families of primitive carnivorous mammals: Miacidae and Viverravidae. These mammals were basal to order Carnivora, the crown-group within the Carnivoramorpha.
Vulpavus is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Miocyon is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from early to late Eocene.
Oodectes is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Palaearctonyx is an extinct genus of omnivorous placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Prodaphaenus is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America during the middle Eocene.
Tapocyon is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America during the middle Eocene. Tapocyon was about the size of a coyote and is believed to have been a good climber that spent a lot of time in trees.
Uintacyon is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Vassacyon is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America and Europe from the late Paleocene to early Eocene. It is considered the largest of the early Eocene mammals.
Xinyuictis is an extinct genus of placental mammals from clade Carnivoraformes, that lived in Asia from early to late Eocene.
Procynodictis is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Quercygale is an extinct genus of placental mammals from extinct family Quercygalidae within clade Carnivoraformes, that lived in Europe during the early to late Eocene. Phylogenetic analysis of the basicranial morphology of carnivoramorphans suggests Quercygale is the most advanced member of clade Carnivoraformes as a sister taxon to crown group Carnivora, predating the split between Feliformia and Caniformia, although another recent study has proposed genus Quercygale should be placed as a stem group within Feliformia.
Gustafsonia is an extinct genus of carnivoran belonging to the family Amphicyonidae. The type species, Gustafsonia cognita, was described in 1986 by Eric Paul Gustafson, who originally interpreted it as a miacid and named it Miacis cognitus. It was subsequently considered to be the only species of the diverse genus Miacis that belonged to the crown-group Carnivora, within the Caniformia, and it was ultimately assigned to the family Amphicyonidae. The type specimen or holotype was discovered in Reeve's bonebed, western Texas, in the Chambers Tuff Formation in 1986. The University of Texas holds this specimen. It is the only confirmed fossil of this species.
Viverravus is an extinct genus of placental mammals from extinct subfamily Viverravinae within extinct family Viverravidae, that lived in North America, Europe and Asia from the middle Paleocene to middle Eocene.
Palaeanodonta is an extinct clade of stem-pangolins. They were insectivorous (myrmecophagous), possibly fossorial, and lived from the middle Paleocene to early Oligocene in North America, Europe and Asia. While the taxonomic grouping of Palaeanodonta has been debated, it is widely thought that they are a sister group to pangolins.
Carnivoraformes is a clade of placental mammals that includes the modern order Carnivora and its extinct stem-relatives.
