Taxonomy Although ''Metasinopa fraasi'' is the only unambiguous species of the genus, the early Miocene species ''Metasinopa napaki'' from Uganda was originally assigned to ''Metasinopa'' by Savage (1965), but was later moved to ''Paracynohyaenodon'' by van Valen (1967), and is now assigned to the Miocene ''Anasinopa'', as ''A. napaki''. ''"Sinopa" ethiopica'' has been assigned to ''Metasinopa'' following Savage (1965), but may be its own genus considering its younger age relative to ''M. fraasi''.

picture info	Hyaenodonta Hyaenodonta ("hyena teeth") is an extinct order of hypercarnivorous placental pan-carnivoran mammals from mirorder Ferae. Hyaenodonts were important mammalian predators that arose during the early Paleocene in Europe and persisted well into the late Miocene. Characteristics Hyaenodonts are characterized by long skulls, slender jaws, slim bodies and a plantigrade stance. They generally ranged in size from 30 to 140 cm at the shoulder. While '' Simbakubwa kutokaafrika'' may have been up to (surpassing the modern polar bear in size) and ''Hyaenodon gigas'' (the largest species from genus '' Hyaenodon'') was as much as 1.4 m high at the shoulder, 3.0 m long and weighed about 330 kg, most of hyaenodonts were in the 5–15 kg range, equivalent to a mid-sized dog. The anatomy of their skulls show that they had a particularly acute sense of smell, while their teeth were adapted for shearing, rather than crushing. Because of their size range, it is probable tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Sinopa ''Sinopa'' ("swift fox") is a genus of hyaenodontid mammal from family Sinopidae, that lived in North America and Asia during the early to middle Eocene. Description ''Sinopa'' was a small genus of hyaenodontid mammals. Its carnassial teeth were the second upper molar and the lower third. ''Sinopa'' species had an estimated weight of 1.33 to 13.97 kilograms. The type specimen was found in the Bridger formation in Uinta County, Wyoming, and existed 50.3 to 46.2 million years ago. Taxonomy The putative African species ''"Sinopa" ethiopica'' from Egypt was considered a species of '' Metasinopa'' by Savage (1965), although Holroyd (1994) considered it a potential new genus related to '' Quasiapterodon''.Lewis, M.

	Ekweeconfractus ''Ekweeconfractus'' ("broken fox") is a genus of teratodontine hyaenodont known from deposits at the Moruorot site in Kenya. The genus contains only a single known species, ''Ekweeconfractus amorui''. The full scientific name of type species translates as "broken fox of stone". Known from a single skull with an intact cranium, it is estimated to have weighed around , similar in size to a large fox. The researchers who described and named the fossil were able to conduct a CT scan of the cranial cavity, revealing that the animal had a comparatively large neocortex for the overall size of its brain, and an estimated encephalisation quotient of 0.54, similar to that of other contemporary African hyaenodonts, but lower than that of ''Hyaenodon''.

picture info	Oligocene The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" ... Epoch.

picture info	Mammal Classification Mammalia is a class of animal within the phylum Chordata. Mammal classification has been through several iterations since Carl Linnaeus initially defined the class. No classification system is universally accepted; McKenna & Bell (1997) and Wilson & Reader (2005) provide useful recent compendiums. Many earlier ideas from Linnaeus et al. have been completely abandoned by modern taxonomists, among these are the idea that bats are related to birds or that humans represent a group outside of other living things. Competing ideas about the relationships of mammal orders do persist and are currently in development. Most significantly in recent years, cladistic thinking has led to an effort to ensure that all taxonomic designations represent monophyletic groups. The field has also seen a recent surge in interest and modification due to the results of molecular phylogenetics.
