Nakalipithecus nakayamai is a fossil ape species. It was a discovery of a 10-million-year-old jawbone with teeth, in a volcanic mud in Nakali, Kenya. "N. nakayamai" is thought to have lived around 9.9 million to 9.8 million years ago. More teeth were found in the same place; eleven of them are thought to belong to this specimen.
