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.
The red panda, also known as the lesser panda, is a small mammal native to the eastern Himalayas and southwestern China. It has dense reddish-brown fur with a black belly and legs, white-lined ears, a mostly white muzzle and a ringed tail. Its head-to-body length is 51–63.5 cm (20.1–25.0 in) with a 28–48.5 cm (11.0–19.1 in) tail, and it weighs between 3.2 and 15 kg. It is well adapted to climbing due to its flexible joints and curved semi-retractile claws.
Ailurinae is a subfamily of Ailuridae. While it is represented by the extant genus Ailurus, there were a handful of genera whose fossils have been found across the Holarctic region. These include the Middle Miocene Magerictis of Spain, the Early Pliocene Pristinailurus of the United States of America and their sister taxon Parailurus of Eurasia and North America in the Pliocene. Unlike Ailurus which is a specialized arboreal bamboo forager, the extinct ailurine species were more generalized and spent their time foraging on the ground.
Amphicyonidae is an extinct family of terrestrial carnivorans belonging to the suborder Caniformia. They first appeared in North America in the middle Eocene, spread to Europe by the late Eocene, and further spread to Asia and Africa by the early Miocene. They had largely disappeared worldwide by the late Miocene, with the latest recorded species at the end of the Miocene in Africa. They were among the first carnivorans to evolve large body size. Amphicyonids are colloquially referred to as "bear-dogs".
Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs, bears, raccoons, and mustelids. The Pinnipedia are also assigned to this group. The center of diversification for the Caniformia is North America and northern Eurasia. Caniformia stands in contrast to the other suborder of Carnivora, the Feliformia, the center of diversification of which was in Africa and southern Asia.
Ailuridae is a family in the mammal order Carnivora. The family consists of the red panda and its extinct relatives.
Hadar or Hadar Formation is a paleontological fossil site located in Mille district, Administrative Zone 1 of the Afar Region, Ethiopia, 15 km upstream (west) of the A1 road's bridge across the Awash River.
Miacis is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene.
Ailuropodinae is a subfamily of Ursidae that contains only one extant species, the giant panda of China. The fossil record of this group has shown that various species of pandas were more widespread across the Holarctic, with species found in places such as Europe, much of Asia and even North America. The earliest pandas were not unlike other modern bear species in that they had an omnivorous diet but by around 2.4 million years ago, pandas have evolved to be more herbivorous.
Feliformia is a suborder within the order Carnivora consisting of "cat-like" carnivorans, including cats, hyenas, mongooses, viverrids, and related taxa. Feliformia stands in contrast to the other suborder of Carnivora, Caniformia.
Simocyon is a genus of extinct carnivoran mammal in the family Ailuridae. Simocyon, which was about the size of a mountain lion, lived in the late Miocene and early Pliocene epochs, and has been found in Europe, Asia, and rarely, North America and Africa.
Alopecocyon is a fossil genus of ailurid belonging to the subfamily Simocyoninae. It has two species, Alopecocyon goeriachensis and Alopecocyon getti. It is based on fragmentary fossils dating to the middle Miocene of both Europe and Asia.
Musteloidea is a superfamily of carnivoran mammals united by shared characteristics of the skull and teeth. Musteloids are the sister group of pinnipeds, the group which includes seals.
Cyonasua is an extinct genus of procyonid from the Late Miocene to Middle Pleistocene of South America. Fossils of Cyonasua have been found in Argentina, Bolivia, Uruguay, and Venezuela. The oldest well-dated fossils of Cyonasua are approximately 7.3 million years old. Most fossils of Cyonasua are late Miocene to early late Pliocene in age, but a single early Pleistocene specimen indicates that members of this genus survived until at least 0.99 million years ago.
Hemicyoninae is an extinct subfamily of Ursidae, often called dog bears. They were bear-like carnivorans living in Europe, North America, Africa and Asia during the Oligocene through Miocene epochs 33.9–5.3 Ma, existing for approximately 28.6 million years. They are sometimes classified as a separate family.
Arctotherium is an extinct genus of the Pleistocene short-faced bears endemic to Central and South America. Arctotherium migrated from North America to South America during the Great American Interchange, following the formation of the Isthmus of Panama during the late Pliocene. The genus consists of one early giant form, A. angustidens, and several succeeding smaller species, which were within the size range of modern bears. Arctotherium was adapted to open and mixed habitat. They are genetically closer to the spectacled bear, than to Arctodus of North America, implying the two extinct forms evolved large size in a convergent manner.
Sivanasua is an extinct genus of carnivorous mammal found across Miocene Europe including Germany, Austria, France, Spain and the Czech Republic. Like other lophocyonids, Sivanasua had unusual lophodont dentition, meaning the molars had ridges across the grinding surface of the molars, an adaptation believed to be indicative of a herbivorous diet.
Amphictis is an extinct genus of ailurid that existed from the Late Oligocene to the Middle Miocene with fossils found in Eurasia and North America with a total of nine described species. The interrelationships of the different species as well as their relationship to the other ailurids is not fully understood. Usually Amphictis is classified in the basal monotypic subfamily Amphictinae, but there is not certain as the genus could potentially be a paraphyletic with the Oligocene species A. borbonica being a potential sister taxon to the ancestor of the subfamily Ailurinae, while a Middle Miocene clade consisting of an anagenesis line from A. prolongata–to–A. wintershofensis–to–A. cuspida being closer to the ancestry of the now extinct Simocyoninae. This is due to the nature of their plesiomorphic nature of their anatomy.
Myacyon is an extinct genus of large sized carnivoran mammals, belonging to the family Amphicyonidae, that lived in Africa during the Miocene epoch. Due to the limited scope and fragmentary nature of the severely damaged holotype, as well as the illustrations in its descriptions, which have been called inadequate, usage of this genus poses serious issues. However, it is notable for being one of the last surviving members of its family and its adaptions to hypercarnivory. Its relationships to other amphicyonids are obscure, and it is not closely related to Bonisicyon, the other late surviving African genus, although it has been proposed that it descends from a species of Cynelos or Namibiocyon.
