Kamoyapithecus
''Kamoyapithecus'' (Kamoya + Greek -''pithekos'' “ape”) was a primate that lived in Africa during the late Oligocene period, about 24.2-27.5 million years ago. First found in 1948 as part of a University of California, Berkeley expedition, it was at first thought to be under a form of ''Proconsul'' by C.T. Madden in 1980, but after a re-examination by Meave Leakey and associates later on, the fossils were moved under a new genus ''Kamoyapithecus'', named after the renowned fossil finder Kamoya Kimeu. The genus is represented by only one species, ''K. hamiltoni''.〔
==Morphology==
''Kamoyapithecus'' is known exclusively by its teeth and jaws. The type specimen, KNM-LS 7, was a right maxillary jaw fragment found during the expedition in 1948. Through this fossil as well as more recent fragments of mandibles and teeth, it has been found that ''Kamoyapithecus'' had very large and robust anterior teeth. The incisors are found to be compressed on the sides, but expanded from top to bottom.
Its teeth also have been found through plane film X-ray to not be thickly enamelled. This suggests that ''Kamoyapithecus'' had more emphasis on foods that did not involve heavy wearing, such as soft fruits, nuts and seeds. This would have been well-placed in the Late-Oligocene in Africa, when forests covered a lot of the land.
Similar affinities with the jaw fragments have been seen with ''Afropithecus'', ''Proconsul'', and the ''Morotopithecus'', but nothing definitive can be stated as to the relationship between these genera and ''Kamoyapithecus'' as the amount of fossil record is very limited. This variation of traits that are expressed within the fragments also makes it difficult to ascertain exactly where ''Kamoyapithecus'' fits in the evolution of humans.〔
