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".
Ferae is a mirorder of placental mammals from grandorder Ferungulata, that groups together clades Pan-Carnivora, which includes modern carnivorans, and Pholidotamorpha, which includes pangolins.
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.
Miacis is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene.
Paroodectes is an extinct genus of placental mammals from clade Carnivoraformes, that lived in Europe during the 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.
Vulpavus is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene.
Miocyon is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from the early to late Eocene.
Oodectes is an extinct paraphyletic genus of 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.
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.
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.
Didymictis is an extinct genus of placental mammals from extinct subfamily Didymictinae within extinct family Viverravidae, that lived in North America and Europe from the late Paleocene to 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.
This paleomammalogy list records new fossil mammal taxa that were described during the year 2012, as well as notes other significant paleomammalogy discoveries and events which occurred during that year.
The Willwood Formation is a sedimentary sequence deposited during the late Paleocene to early Eocene, or Clarkforkian, Wasatchian and Bridgerian in the NALMA classification.
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.
Hyaenodonta is an extinct order of hypercarnivorous placental mammals of clade Pan-Carnivora from mirorder Ferae. Hyaenodonts were important mammalian predators that arose during the early Paleocene in Europe and persisted well into the late Miocene.
Chiromyoides is a small plesiadapid primatomorph that is known for its unusually robust upper and lower incisors, deep dentary, and comparatively small cheek teeth. Species of Chiromyoides are known from the middle Tiffanian through late Clarkforkian North American Land Mammal Ages (NALMA) of western North America, and from late Paleocene deposits in the Paris Basin, France.
