Sectisodon
''Sectisodon'' ("cutting tooth") is an extinct genus of hyainailourid hyaenodont mammal of the polyphyletic tribe Hyainailourini within paraphyletic subfamily Hyainailourinae from early Oligocene to early Miocene deposits in Egypt and Uganda }), is a landlocked country in East Africa. The country is bordered to the east by Kenya, to the north by South Sudan, to the west by the Democratic Republic of the Congo, to the south-west by Rwanda, and to the south by Tanzania. The south .... Description Morales and Pickford (2017, p. 346) diagnose ''Sectisodon'' as follows: "Hyainailourinae of small dimensions, M1 and M2 of similar length. M2 with paracone and metacone fused together, tall and pointed. Protocone very reduced, flattened and extending basally beyond the base of the paracone. Anterior cingulum with a well-defined parastyle with a moderate buccal cingulum. M2 and M1 with the metastyle quite a bit longer than the paracone-metacone. P3 short, with tall main cus ...

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. Rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
