Isohyaenodon

	Isohyaenodon ''Isohyaenodon'' ("equal to Hyaenodon") is an extinct polyphyletic genus of hyainailourid hyaenodont mammal from polyphyletic subtribe Isohyaenodontina (of the polyphyletic tribe Hyainailourini within paraphyletic subfamily Hyainailourinae). Remains are known from early to middle Miocene deposits in Kenya, East Africa. Description ''Isohyaenodon'' is distinguished from ''Hyaenodon'' in having more robust molars, lower molars with a subequal paraconid and protoconid, and upper molars with a more well-developed protocone. Classification and phylogeny Taxonomy ''Isohyaenodon'' was considered possibly the same genus as '' Leakitherium'' from the same region by Van Valen (1967), but subsequent studies have rejected this assumption. ''Isohyaenodon pilgrimi'' Savage, 1965 was formerly assigned to this genus, but has been renamed '' Exiguodon pilgrimi''. Phylogeny The phylogenetic relationships of genus ''Isohyaenodon'' are shown in the following cladogram: See also * Mammal classi ...

	Exiguodon ''Exiguodon'' ("strict tooth") is an extinct genus of Hyainailouridae, hyainailourid Hyaenodonta, hyaenodont mammal of the polyphyletic tribe Hyainailourini within paraphyletic subfamily Hyainailourinae. Remains are known from early Miocene deposits in Kenya and Uganda, in East Africa. Description ''Exiguodon'' is distinguished from other hyainailourines by the following features: diminutive dimensions, lower molars (m3 – m2) with greatly reduced talonid; protoconid and paraconid similar in size. Paraconid of the molars lingually oriented. M2 and M1 close in size and morphology. Occlusal outline sub-triangular, with greatly reduced protocone, which appears like an antero-lingual cingulum which extends anteriorly and buccally. Presence of a strong parastyle in an antero-buccal position, united to the apex of the paracone by a well defined crista. The buccal cingulum borders a wide buccal platform, particularly large in the M2. Paracone tall and narrow, elongated blade-like metas ...

	Hyainailouridae Hyainailouridae ("hyena-cats") is a paraphyletic family of extinct predatory mammals from extinct paraphyletic superfamily Hyainailouroidea within extinct order Hyaenodonta. Hyaenodontids arose during the middle Eocene and persisted well into the middle Miocene. Fossils of this group have been found in Asia, Africa, North America and Europe. General characteristics Hyainailourids 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 some measured as much as 1.4 m high at the shoulder with head-body length up to 3.2 m and weighed up to 1,500 kg, most 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. At least one hyainailourid lineage, Apterodontinae, was specialised for aquatic, otter-like habits. Range ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
