Viverravidae : ウィキペディア英語版 | Viverravidae
Viverravidae is an extinct family within the superfamily Miacoidea. They are related to carnivorans, and lived from the early Palaeocene to the Eocene. In viverravids, the number of molars is reduced to two and the skull is elongated. Viverravidae is a monophyletic family, a plesion-group. They are not thought to be related to any extant carnivorans. The viverravids were thought to be the earliest carnivorans: they first appeared in the Paleocene of North America about 60 million years ago. Recent cranial morphology evidence now places them outside the order Carnivora. == References ==
