Miacid
Miacids are extinct primitive carnivoramorphans within the family Miacidae that lived during the Paleocene and Eocene epochs, about 62–34 million years ago. Miacids existed for approximately . Miacids are thought to have evolved into the modern carnivorous mammals of the order Carnivora. They were small carnivores, superficially marten-like or civet-like with long, lithe bodies and long tails. Some species were arboreal, while others lived on the ground. They probably fed on invertebrates, lizards, birds, and smaller mammals like shrews and opossums. Their teeth and skulls show that the miacids were less developed than modern carnivorans. They had carnivoran-type carnassials, but lacked fully ossified auditory bullae (rounded protrusions). Classification Miacidae as traditionally conceived is not a monophyletic group; it is a paraphyletic array of stem taxa. Traditionally, Miacidae and Viverravidae had been classified in a superfamily, Miacoidea. Today, Carnivor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paramiacis
''Paramiacis'' is an extinct genus of Miacidae. Christian Mathis has defined to make a difference between the miacids from Europe and the American genus ''Miacis''. There are two species of it, ''P. exilis'' (Henri Filhol, 1876) and ''P. teilhardi'' (Mathis, 1987) - which were long believed to be only sexual dimorphism.

Miacis
''Miacis'' is a genus of extinct carnivorous mammals that appeared in the late Paleocene and continued through the Eocene. The genus ''Miacis'' is not monophyletic but a diverse collection of species that belong to the stemgroup within the Carnivoramorpha.Wesley-Hunt, G.D.; Flynn J.J. (2005). Phylogeny of the Carnivora: Basal Relationships Among the Carnivoramorphans, and Assessment of the Position of 'Miacoidea' Relative to Carnivora. ''Journal of Systematic Palaeontology'', 3: 1-28. As such, most ''Miacis'' species belong to the group of early carnivores that represent the ancestors of the modern order, the crown-group Carnivora. However, the species ''Miacis cognitus'' (now ''Gustafsonia'') is placed not in the stem-group but among the Caniformia,Spaulding, M.; Flynn J.J.; Stucky, R.K.

Carnivora
Carnivora is a monophyletic order of placental mammals consisting of the most recent common ancestor of all cat-like and dog-like animals, and all descendants of that ancestor. Members of this group are formally referred to as carnivorans, and have evolved to specialize in eating flesh. The order is the fifth largest order of mammals, comprising at least 279 species. Carnivorans live on every major landmass and in a variety of habitats, ranging from the cold polar regions to the hyper-arid region of the Sahara Desert to the open seas. They come in a very large array of different body plans in contrasting shapes and sizes. Carnivora can be divided into two subclades: the cat-like Feliformia and the dog-like Caniformia, which are differentiated based on the structure of their ear bones and cranial features. The feliforms include families such as the cats, the hyenas, the mongooses and the civets. The majority of feliform species are found in the Old World, though the cat ...

Palaearctonyx
''Palaearctonyx'' is an extinct genus of omnivorous Miacidae which inhabited North America during the Eocene living from 50.3 to 46.2 Ma and existed for approximately . Taxonomy ''Palaearctonyx'' was named by Matthew (1909). Its type is ''Palaearctonyx meadi''. It was assigned to Caniformia by Flynn and Galiano (1982); and to Miacidae by Matthew (1909) and Flynn (1998).W. D. Matthew. 1909. The Carnivora and Insectivora of the Bridger Basin, middle Eocene.

''Quercygale'' is an extinct genus of Miacidae, primitive carnivores that lived during the Eocene. The genus contains four species: ''Q. angustidens'', ''Q. hastingsae'', ''Q. helvetica'', and ''Q. smithi''. Phylogenetic analysis of the basicranial morphology of miacid carnivoramorphans suggests ''Quercygale'' is the most advanced miacid and sister to crown group Carnivora, predating the split between Feliformia and Caniformia., although another recent study places them as a stem group within Feliformia.

Paroodectes
''Paroodectes'' is a miacid animal that lived during the early Eocene (ca. 50 million years ago) in the rain forests and swamps of the present-day Germany. It was a prehistoric predator that had the size and the appearance of a cat and was well adapted to climbing, as is apparent from its limbs, joints and shoulder bones. Its long tail gave balance for tree climbing and jumping from branch to branch. ''Paroodectes'' probably hunted insects, rodents and small primates in the tree tops. Only one species of ''Paroodectes'' (''P. feisti'') has been found, and this was at the Messel Pit located southeast of Frankfurt, Germany. The pit was formed during the Geiseltalian Period (or Middle Eocene) about 50 million years ago. The fossil was found by private collector Otto Feist in 1974. It was described in 1980 by Rainer Springhorn who said the following about the species: "The odontological features of the Messel-Miacid are nearest to the new world genus Oodectes from the Bridger Basin ( ...
