Nacholapithecus
Extinct genus of hominoids
Nacholapithecus kerioi was an ape that lived 15-14 million years ago 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.
Together with other Kenyapithecinae such as Equatorius, Kenyapithecus, and Griphopithecus, Nacholapithecus displayed synapomorphies with Anoiapithecus.
01Taxonomy
Nacholapithecus was initially classified as belonging in Kenyapithecus, then attributed to Equatorius (with Equatorius perhaps grouped into a subfamily Equatorinae, instead of both species in Afropithecini), finally recognised by Ishida et al. (1999) as a separate genus. Classified perhaps as a member of the family Proconsulidae.
02Fossil 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. The formation is largely part of the north-western rift flank overlying the Nachola Formation.
03Palaeobiology
Morphological evidence suggests arboreal quadrupedalism was for N. kerioi the primary method of locomotion.
