Nyanzapithecus pickfordi was a primate from the Middle Miocene of Maboko Island, Nyanza Province, Kenya. This species had an average body mass of around (). ==Taxonomy== Fifteen cranio-dental specimens of this type of primate were collected from the island between the years 1933-73. During an expedition to Maboko Island in 1982–83, paleoanthropologist Martin Pickford recovered more than a hundred small catarrhine fossils. Among them, described the new genus and species ''Nyanzapithecus pickfordi'', characterized by several dental specializations, and also transferred the ''Rangwapithecus'' species ''R. vancouveringi'' to the genus renaming it ''N. vancouveringorum''. ''Nyanzapithecus'' was considered closely related to ''Rangwapithecus'' and ''Mabokopithecus'' based on dental similarities, and an early relative of ''Oreopithecus bambolii''. ''Nyanzapithecus'' was originally included in ''Oreopithecidae'' before being transferred to ''Proconsulidae''. described a new species, ''N. harrisoni'', from Nachola, Kenya. considered ''Mabokopithecus clarki'' congeneric and even conspecific with ''N. pickfordi'' and thus renamed the latter ''Mabokopithecus pickfordi/clarki'' and Kunimatsu's species ''M. harrisoni''.
