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 early to middle Eocene.
Miacoidea is a former paraphyletic superfamily of extinct placental mammals that lived during the Paleocene and Eocene epochs, about 66-33,9 million years ago. This group had been traditionally divided into two families of primitive carnivorous mammals: Miacidae and Viverravidae. These mammals were basal to order Carnivora, the crown-group within the Carnivoramorpha.
Vulpavus is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Miocyon is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from early to late Eocene.
Oodectes is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Palaearctonyx is an extinct genus of omnivorous placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
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.
Uintacyon is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
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.
Bryanictis is an extinct genus of placental mammals from extinct subfamily Didymictinae within extinct family Viverravidae, that lived in North America, from the early to late Paleocene.
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.
Procynodictis is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Floridaceras is an extinct genus of Rhinocerotidae (rhinoceros) of the Miocene epoch, endemic to North America, living from around ~20.6–16.3 Ma, existing for approximately 4.3 million years.
Ekgmowechashala is an extinct genus of primate belonging to Adapiformes.
The Bridger Formation is a geologic formation in southwestern Wyoming. It preserves fossils dating back to the Bridgerian and Uintan stages of the Paleogene Period. The formation was named by American geologist Ferdinand Vandeveer Hayden for Fort Bridger, which had itself been named for mountain man Jim Bridger. The Bridger Wilderness covers much of the Bridger Formation's area.
Viverravus is an extinct genus of placental mammals from extinct subfamily Viverravinae within extinct family Viverravidae, that lived in North America, Europe and Asia from the middle Paleocene to middle Eocene.
Protictis is an extinct paraphyletic genus of placental mammals from extinct subfamily Didymictinae within extinct family Viverravidae, that lived in North America from early Paleocene to middle Eocene.
Hemipsalodon is an extinct genus of hyainailourid hyaenodonts from the paraphyletic subfamily Hyainailourinae that lived in North America during the middle to late Eocene.
Limnocyonidae is a family of extinct predatory mammals from extinct order Hyaenodonta. Fossil remains of these mammals are known from late Paleocene to late Eocene deposits in North America and Asia. Limnocyonids had only two molars in the upper and lower dentition.
