Afropithecus
''Afropithecus turkanensis'' is a Miocene hominoid which was excavated from a small site near Lake Turkana called Kalodirr in northern Kenya in 1986 and was named by Richard Leakey and Meave Leakey. The estimated age of ''Afropithecus'' is between 16 and 18 million years old, which was determined with radiometric dating techniques and the geological studies conducted by Broschetto and Brown from the University of Utah.〔 In total there are 46 recovered specimens from Kalodirr relating to ''Afropithecus'' consisting of cranial, mandible, dentition and post-cranial remains. The type specimen of ''Afropithecus turkanensis'' is KNM-WK 16999.〔
==Morphology==
Leakey and Leakey first described ''Afropithecus turkanensis'' to be a large hominoid which appeared to have relatively thick enamel. Leakey suggested that ''A. turkanensis'' shared postcranial features with the species ''Prosconsul nyanzae'', which is the best known genus Miocene with literally hundreds of fossils having been found representing almost all skeletal elements, and sharing cranial features with ''Aegyptopithecus zeuxis'' and dental features with ''Heliopithecus'' which had two weathered molars that indicated a general distinction from known large early catarrhines, and later concluded that ''A. turkenensis'' was a primitive, arboreal quadruped similar to ''P. nyanzae'', and that ''A. turkanensis'' had primitive facial morphology and derived dental characteristics that would suggest a diet of hard fruits.
