Protictis
''Protictis'' ("first weasel") is an extinct paraphyletic genus of placental mammals from extinct subfamily Didymictinae within extinct family Viverravidae, that lived in North America during late Paleocene. Etymology The name of genus ''Protictis'' comes and Latin ''ictis''. Description ''Protictis'' was a mongoose-like animal that was lightly built. The species had variable sizes. Parts of the skeleton of ''P. haydenianus'' are known and this species was about 75 cm long, comparable to the related ''Didymictis'' and the modern day Asian civets. The skull of ''P. simpsoni'' shows that this species was larger than ''P. haydenianus''. ''P. minor'' on the other hand was smaller than ''P. haydenianus''. The morphology of the limb bones of ''P haydenianus'' points at a scansorial lifestyle. ''Protictis'' had two times as many teeth as modern carnivores. The characteristic carnassials of carnivores were already clearly developed in ''Protictis'', but the long and pointy t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.Malcolm C. McKenna, Susan K. Bell: ''Classification of Mammals: Above the Species Level'' in Columbia University Press, New York (1997), 631 Seiten. They were once thought to be earliest carnivorans and ancestral to extant carnivorans, but now are placed outside the order Carnivora based on cranial morphology as a relatives (a plesion-group) to extant carnivorans. General characteristics Wang and Tedford propose that they arose in North America 66-60 million years ago, spread to Asia then later to Europe, and were the first carnivoramorphans and possessed the first true pair of carnassial teeth.Wang, Xiaoming; Tedford, Richard H.

Didymictis
''Didymictis'' ("double weasel") 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. Description ''Didymictis'' is the only viverravid genus for which there are considerable postcranial remains. The genus was primarily terrestrial but at least partly cursorial, similar to a civets. ''Didymictis'' has an elongated and relatively large skull with small and low braincase and a long and narrow basicranial region. The occipital and sagittal crests are very high. The limbs are of moderate length with subdigitigrade and five-toed feet. The dentition () contrast those of basal carnivoraforms by the sharp differentiation between sectorial and tubercular dentition, the loss of the last molar and an elongated second molar, similar to the dentition in bears and raccoons. Comparing ''Didymictis'' to ''Vulpavus'', a much smaller and more agile carn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carnivoraformes
Carnivoraformes ("carnivoran-like forms") is a clade of placental mammals that includes the modern order Carnivora and its extinct stem-relatives. Classification and phylogeny Classification In 2010 Flynn, Finarelli & Spaulding named a new clade Carnivoraformes within Carnivoramorpha, containing carnivorans and "miacids" but not viverravids. The authors defined Carnivoraformes as the clade containing Carnivora and all taxa that are more closely related to Carnivora (represented by ''Canis lupus'') than to viverravids (represented by '' Viverravus gracilis''). * ''Clade'': Carnivoraformes ** Order: Carnivora (carnivorans) *** Suborder: Caniformia ("dog-like" carnivorans) *** Suborder: Feliformia ("cat-like" carnivorans) ** Family: † Quercygalidae ** (unranked): †''Gracilocyon''/''Oodectes'' clade *** Genus: †'' Eogale'' *** Genus: †''Gracilocyon''(paraphyletic genus) *** Genus: †''Oodectes''(paraphyletic genus) *** Genus: †''Paramiacis'' *** Genus: †''Paroode ...
