Viverravidae

Viverravidae ("ancestors of viverrids") 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 (a plesion-group) to extant carnivorans.

Ictidopappus ("grandfather of weasels") is an extinct genus of mammals from extinct subfamily Ictidopappinae within extinct family Viverravidae, that lived in North America during the early Paleocene.

Viverravus ("ancestor of Viverra") 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.

Didymictis ("double weasel") is an extinct genus of placental mammals from the extinct subfamily Didymictinae within the extinct family Viverravidae, that lived in North America and Europe from the Late Paleocene to Middle Eocene.

Bryanictis ("Bryan's weasel") 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.

Protictis ("first weasel") 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.

Raphictis ("needle weasel") is an extinct genus of placental mammals from extinct subfamily Didymictinae within extinct family Viverravidae, that lived in North America during late Paleocene.

Pristinictis ("primitive weasel") is an extinct genus of placental mammals from extinct subfamily Didymictinae within extinct family Viverravidae, that lived in North America during middle Paleocene.
