Nacholapithecus
Nacholapithecus kerioi was an ape that lived 14-15 million years ago[1] during the Middle Miocene.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.[2] Together with other Kenyapithecinae such as Equatorius, Kenyapithecus, and Griphopithecus, Nacholapithecus displayed synapomorphies with Anoiapithecus.[3] Nacholapithecus was initially classified as belonging in Kenyapithecus,[4] then attributed[5] to Equatorius (with Equatorius perhaps grouped into a subfamily Equatorinae, instead of both species in Afropithecini),[6][7] finally recognised by Ishida et al. (1999) as a separate genus.[11] 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.
