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.
Pseudaelurus is a prehistoric cat that lived in Europe, Asia and North America in the Miocene between approximately twenty and eight million years ago. It is considered to be a paraphyletic grade ancestral to living felines and pantherines as well as the extinct machairodonts (saber-tooths), and is a successor to Proailurus. It originated from Eurasia and was the first cat to reach North America, when it entered the continent at about 18.5 Ma ending a 'cat-gap' of 7 million years. The slender proportions of the animal, together with its short, viverrid-like legs, suggest that it may have been an agile climber of trees.
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".
Nimravidae is an extinct family of carnivorans, sometimes known as false saber-toothed cats, whose fossils are found in North America and Eurasia. Not considered to belong to the true cats, the nimravids are generally considered closely related and classified as a distinct family in the suborder Feliformia. Fossils have been dated from the Middle Eocene through the Late Miocene epochs, spanning about 33.2 million years.
Ailuridae is a family in the mammal order Carnivora. The family consists of the red panda and its extinct relatives.
Amphicyon is an extinct genus of large carnivorans belonging to the family Amphicyonidae, subfamily Amphicyoninae, from the Miocene epoch. Members of this family received their vernacular name for possessing bear-like and dog-like features. They ranged over North America, Europe, Asia, and Africa.
Barbourofelidae is an extinct family of carnivorans of the suborder Feliformia, sometimes known as false saber-toothed cats, that lived in North America, Eurasia and Africa during the Miocene epoch and existed for about 7.9 million years. Thought to be an independent lineage from the Nimravidae and Machairodontinae, which had all attained elongated canines, recent research argues that it may be a subfamily of the Nimravidae, extending its biochronological range into the Miocene, although this issue is not yet fully resolved.
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.
Agnotherium is a genus of large sized carnivoran mammals, belonging to the Amphicyonidae, which has been found in Western Europe, and possibly China and Northern Africa, and lived during the Late Miocene epoch. Despite only being known from fragmentary remains, the genus notable for hypercarnivorous adaptions, which have been said to represent the "apex" among its family.
Asiavorator is an extinct genus of civet-like carnivoran belonging in the family Stenoplesictidae. It was endemic to Asia and lived during the Eocene and Oligocene epochs.
Palaeogale is an extinct genus of carnivorous mammal known from the Late Eocene, Oligocene, and Early Miocene of North America, Europe, and Eastern Asia. A small carnivore often associated with the mustelids, Palaeogale might have been similar to living genets, civets, and linsangs.
Cerro de los Batallones is a hill at Torrejón de Velasco, Madrid, Spain where a number of fossil sites from the Upper Miocene (MN10) have been found. Nine sites have been discovered with predominantly vertebrate fossils, invertebrates and plants being less represented. The first deposits were discovered accidentally in July 1991.
Tchadailurus is a genus of machairodontine felid from the late Miocene of Chad, Africa.
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 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, 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.
Thaumastocyoninae is an extinct subfamily of amphicyonids, large terrestrial carnivores, which inhabited what is now Europe during the Miocene epoch. The subfamily was erected by Hürzeler (1940), and is defined by the complete suppression of m1 metaconid, reduction of the premolars, except the p4, which is reinforced, and the oblique abrasion of the teeth, and the possession of hypercarnivorous tendencies. Thaumastocyonines are poorly known, with only about 65 dental specimens, most of those isolated teeth, being known as of 2020, although more complete remains have recently been discovered.
Actiocyon was an extinct genus of ailurid that existed from the Middle Miocene of North America. The type species, Actiocyon leardi, was described in 1947 by the American paleontologist Chester Stock.
Protursus is a fossil genus of ailurid with a single species Protursus simpsoni, known from a single left m2 tooth.
Peignecyon is an extinct genus of large carnivorans belonging to the family Amphicyonidae. It belongs to the subfamily Thaumastocyoninae, which is characterized by their adaptions towards hypercarnivory. Whereas most other thaumastocyonines are often only known from fragmentary remains and isolated teeth, Peignecyon is known from a variety of well-preserved remains. It contains a single species, P. felinoides from the Early Miocene of the Czech Republic.
