Quercygale ("weasel from Quercy") is an extinct genus of placental mammals from the clade Carnivoraformes, that lived in Europe during the early to late Eocene. [7] [8]
Currently, Quercygale is either assigned to no family (i. e. it is just classified as one of the basal genera of Carnivoraformes) or it is assigned to the paraphyletic family Miacidae. [9] Phylogenetic analysis of the basicranial morphology of carnivoramorphans suggests that Quercygale is the most advanced member of the clade Carnivoraformes as a sister taxon to crown-clade Carnivora, predating the split between Feliformia and Caniformia. [10] [11] [12] Another recent study, however, has proposed that the genus Quercygale should be placed as a stem group within Feliformia. [13]
In the past (till about 2010), Quercygale was assigned either to the family Miacidae (which was considered monophyletic in the past), or to the family Viverravidae. Only one author (Kretzoi 1945) classified it as the only genus of its own family Quercygalidae (Quercygalidae, however, was considered another name for the family Miacidae by another author). Alternatively, individual authors considered Quercygale to be a basal genus of Caniformia or a synonym of the genus Tapocyon . [10] [14] [15]

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.
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.
Hyaenodon ("hyena-tooth") is an extinct genus of carnivorous placental mammals from extinct tribe Hyaenodontini within extinct subfamily Hyaenodontinae, that lived in Eurasia and North America from the middle Eocene, throughout the Oligocene, to the early Miocene.
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 the early to middle Eocene.
Carnivoramorpha is a clade of placental mammals of clade Pan-Carnivora from mirorder Ferae, that includes the modern order Carnivora and its extinct stem-relatives.
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.
Vulpavus is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene.
Oodectes is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene.
Palaearctonyx is an extinct genus of omnivorous placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene.
Paramiacis is an extinct genus of placental mammals from clade Carnivoraformes, that lived in Europe from the middle to late Eocene. Species P. exilis and P. teilhardi were long believed to be the same species, with differences that were only represented as an example of sexual dimorphism.
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 the early to late Eocene.
Messelogale is an extinct genus of placental mammals from clade Carnivoraformes, that lived in Europe during the middle Eocene.
Gracilocyon is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America and Europe from the late Paleocene to the early Eocene.
Dormaalocyon is an extinct genus of placental mammals from clade Carnivoraformes, that lived in Europe during the early Eocene. The type species, Dormaalocyon latouri, was discovered when fossils were unearthed in the village of Dormaal, near Zoutleeuw, in the Belgian province of Flemish Brabant.
The Lignites de Soissonais is a geologic formation in the Var, Marne departments of France. It preserves fossils dating back to the Ypresian stage of the Eocene period.
Angelarctocyon is an extinct genus of Amphicyonidae, which belongs to the order Carnivora.
