Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.

Palaearctonyx
''Palaearctonyx'' is an extinct genus of omnivorous Miacidae which inhabited North America during the Eocene The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', " ... 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.

Miacis Sp
''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.

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 ( ...

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 Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction.

Quercygale
''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 Feliformia is a suborder within the order Carnivora consisting of "cat-like" carnivorans, including cats (large and small), hyenas, mongooses, viverrids, and related taxa. Feliformia stands in contrast to the other suborder of Carnivora, Canifor ... and Caniformia., although another recent study places them as a stem group within Feliformia.

Wolf
The wolf (''Canis lupus''; : wolves), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest extant member of the family Canidae. It is also distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large prey, its more social nature, and its highly advanc ...
