Viverra
Viverra is a mammalian genus that was first named and described by Carl Linnaeus in 1758 as comprising several species including the large Indian civet (V. zibetha). The genus was subordinated to the viverrid family by John Edward Gray in 1821.
Proailurus
Proailurus is an extinct felid genus that lived in Europe and Asia approximately 25–30.8 million years ago in the Late Oligocene and Miocene. Fossils have been found in Mongolia, Germany, and Spain.

Machairodus
Machairodus (from Ancient Greek μάχαιρα (mákhaira), a type of ancient sword, and ὀδούς (odoús), meaning "tooth") is a genus of large machairodont or saber-toothed cat that lived in Africa and Eurasia during the Middle to Late Miocene, from 12.5 million to 8.7 million years ago. It is the animal from which the subfamily Machairodontinae gets its name. The genus currently consists of four named species: M. alberidae, M. aphanistus, M. laskerevi, and M. robinsoni. The genus is currently usually placed as one of the most basal members of the tribe Homotherini, and the ancestor of later members of

Arctoidea
Arctoidea is an infraorder of mostly carnivorous mammals which include the extinct Hemicyonidae (dog-bears), and the extant Musteloidea (weasels, raccoons, skunks, red pandas), Pinnipedia (seals, sea lions), and Ursidae (bears), found in all continents from the Eocene, , to the present. The oldest group of the clade is the bears, as their CMAH gene is still intact. The gene became non-functional in the common ancestor of the Mustelida (the musteloids and pinnipeds). Arctoids are caniforms, along with dogs (canids) and extinct bear dogs (Amphicyonidae). The earliest caniforms were superficially
Barbourofelidae
Barbourofelinae is a subfamily of carnivorans within the extinct family of feliforms known as Nimravidae. Sometimes known as false saber-toothed cats, that lived in North America, Eurasia and Africa during the Miocene epoch (22.8—7 million years ago) and existed for about . Once thought to have been an independent lineage from the nimravids and Machairodontinae, most experts over the recent years have reclassified them as nimravids.

Ictitherium
Ictitherium (meaning "weasel beast") is an extinct genus belonging to the family Hyaenidae and the subfamily Ictitheriinae erected by Trouessart in 1897. Ictitherium lived throughout Eurasia during the Late Miocene.

Metailurini
Metailurini is an extinct taxonomic tribe of large saber-toothed cats that lived in Africa, Asia, Europe, and North America from the Miocene to the Pleistocene.
Amphicynodontidae
Amphicynodontidae is a probable clade of extinct arctoids. While some researchers consider this group to be an extinct subfamily of bears, a variety of morphological evidence links amphicynodontines with pinnipeds, as the group were semi-aquatic otter-like mammals. In addition to the support of the pinniped–amphicynodontine clade, other morphological and some molecular analyses support bears being the closest living relatives to pinnipeds. According to McKenna and Bell (1997) Amphicynodontinae are classified as stem-pinnipeds in the superfamily Phocoidea. Fossils of these mammals have been fou
Hemicyon
Hemicyon, also known as the "dog-bear" (literally "half dog", from Greek (half) + (dog)), is an extinct genus of hemicyonine bear, which probably originated in Eurasia but was found in Europe, Asia and North America during the Miocene epoch (), existing for approximately . Hemicyon is the best-known genus in the Hemicyoninae, a subfamily intermediate between bears and their Caniform ancestors but most often classified as bears. Hemicyonid bears should not be confused with Amphicyonids (bear-dogs), which are their own separate family of carnivores.

Simocyon
Simocyon ("short-snouted dog") 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.

Nimravides
Nimravides is a genus of extinct saber-toothed cats that was endemic in North America during the Late Miocene, from 11 to 6.5 Ma. Despite its scientific name, Nimravides does not belong to the Nimravidae, but is a true cat belonging to the family Felidae.
Chamitataxus
Chamitataxus is a prehistoric badger genus. Chamitataxus avitus is the only known species of the genus. Chamitataxus lived during the Late Miocene, around 6 million years ago in what is now North America. Out of the three taxidiine badger genera to have existed on the continent, Chamitataxus is the most primitive. Very few taxideine badger remains have been uncovered to date, with only prehistoric Taxidea and Pliotaxidea specimens being discovered prior to the Chamitataxus holotype being found.

Sansanosmilus
Sansanosmilus is an extinct genus of carnivorous mammal of the subfamily, Barbourofelinae and was found in Eurasia and lived during the Miocene from 16 to 11.4 mya, existing for . Including supplementary materials

Ekorus ekakeran
Ekorus ekakeran is a large, extinct mustelid mammal. Fossils, including largely complete skeletons, are known from the late Miocene of Kenya.

Ysengrinia
Ysengrinia is an extinct genus of carnivoran in the family Amphicyonidae, that lived during the Late Oligocene to Early Miocene. Fossil remains have been discovered in Western Europe, the United States and possibly China. The European species are among the earliest known members of the Thaumastocyoninae, a group of aberrant amphicyonids showcasing hypercarnivorous adations, but are only known from fragmentary remains. The American species is much better preserved and shows a robust, black-bear sized predator. These fossils play an important role in our understanding of the biotic interchange b
Homotherini
Homotherini (Machairodontini) is a tribe (or subtribe) of saber-toothed cats of the family Felidae (true cats). The tribe is commonly known as scimitar-toothed cats. These saber-toothed cats were endemic to North America, Europe, Asia, Africa, and South America from the Miocene to Pleistocene living from c. 12.5 Ma until c. 12,000 years ago. The evolutionary relationship between the tribes Homotherini and Machairodontini cause paleontologists to classify Homotherini either as a subtribe of Machairodontini, or the same tribe often using either name interchangeably.
Prosansanosmilus
Prosansanosmilus is an extinct genus of barbourofelin that lived in Europe during the Early Miocene epoch from 18 to 15.97 mya, existing for approximately . Including supplementary materials It contains Prosansanosmilus peregrinus, which died out in the Miocene epoch.

They are sometimes classified as a separate family.
Amphicyoninae
Amphicyoninae is a subfamily of extinct amphicyonids, large terrestrial carnivores sometimes called "bear-dogs", belonging to the suborder Caniformia, which inhabited North America, Eurasia, and Africa from the middle Eocene to the late Miocene.

Amphictis
Amphictis is an extinct genus of ailurids 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 no certainty 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 (today consisting j

==Taxonomy and evolution==
===Taxonomic history===
In 1858, the paleontologist Joseph Leidy described a new species of cat, Felis intrepidus, based on lower jaw fragments (a left ramus, described, and a right ramus, mentioned only and now lost) found somewhere in Nebraska near the Niobrara river. The fragments were later determined to have come from the lower Valentine Formation, making them late Barstovian in ag
Eomellivora
Eomellivora is an extinct genus of prehistoric mustelids, closely related to the honey badger, known from Eurasia and North America, and tentatively Africa. It was one of the biggest mustelids ever known, bigger and more hypercarnivorous than the modern wolverine. Using equations by Legendre (1986) for calculating body mass for mammals through linear dimensions of the first lower molar, Eomellivora averaged roughly 50 kg (based on measurements reported in Valenciano et al., 2015).
