Nacholapithecus kerioi was an ape that lived 15-14 million years ago{{Harvnb|Sawada|Saneyoshi|Nakayama|Sakai|2006}} during the Middle Miocene. Fossils have been found in the Nachola formation in northern Kenya. The only member of the genus Nacholapithecus, it is thought to be a key genus in early hominid evolution. Similar in body plan to Proconsul, it had a long vertebral column with six lumbar vertebrae, no tail, a narrow torso, large upper limbs with mobile shoulder joints, and long feet.{{Harvnb|Henke|Hardt|2007| p=1020}}
Together with other Kenyapithecinae such as Equatorius, Kenyapithecus, and Griphopithecus, Nacholapithecus displayed synapomorphies with Anoiapithecus.{{Harvnb|Moyà-Solà|Alba|Almécija|Casanovas-Vilar|2009}}
Taxonomy
Nacholapithecus was initially classified as belonging in Kenyapithecus,{{Harvnb|Ishida|Pichford|Nakaya|Nakano|1984}} then attributed{{Harvnb|Ward|Brown|Hill|Kelley|1999}} to Equatorius (with Equatorius perhaps grouped into a subfamily Equatorinae, instead of both species in Afropithecini),{{Harvnb|Cameron|2004}}{{Harvnb|Cameron|2004| p=101}} finally recognised by Ishida et al. (1999) as a separate genus.{{Harvnb|Ishida|Kunimatsu|Nakatsukasa|Nakano|1999}}{{Harvnb|Russon|Begun|2004| p=305}}{{Harvnb|Ishida|Kunimatsu|Takano|Nakano|2004| loc=Abstract}} Classified perhaps as a member of the family Proconsulidae.{{Harvnb|Zalmout|Sanders|MacLatchy|Gunnell|2010}}
Fossil finds
Nacholapithecus kerioi is known from the lowest part of the Aka Aiteputh Formation, one of five formations in the Neogene System in Nachola, Samburu District, northern Kenya.{{Harvnb|Nakatsukasa|Kunimatsu|2009| loc=Abstract}}{{Harvnb|Sawada|Saneyoshi|Nakayama|Sakai|2006}} The formation is largely part of the north-western rift flank overlying the Nachola Formation.{{Harvnb|Ishida|Tuttle|Pickford|Ogihara|2006| p=74}}
