However, the Yeti is generally described as bipedal, and most scientists believe " Gigantopithecus " to have been quadrupedal, and so massive that, unless it evolved specifically as a bipedal ape ( like " Oreopithecus " and the hominids ), walking upright would have been even more difficult for the now extinct primate than it is for its extant quadrupedal relative, the orangutan.

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.
