Theropithecus oswaldi
Extinct species of Old World monkey From Wikipedia, the free encyclopedia
Theropithecus oswaldi is an extinct species of Theropithecus from the early to middle Pleistocene of Kenya, Ethiopia, Tanzania, South Africa, Spain, Morocco, and Algeria.[1] The species went extinct in South Africa around 1 million years ago.[2] Having existed alongside hominins like Homo erectus, it is likely that conflict with early humans played a role in their extinction as a site has been found with many juveniles butchered.[3][4]

Description
It is remarkable for its large size compared to other Old World monkeys. One source projects a specimen of Theropithecus oswaldi to have weighed 72 kg (159 lb).[5] Postcranial fossils found of this species are much greater in size than extant papionins, including the mandrill.[6]
Palaeoecology
According to δ13C values from fossils of the species from Swartkrans, it was a specialised grazer.[7] A dental microwear study based on fossils from the Omo Valley suggests that the diet of T. oswaldi, like that of the modern day gelada, consisted primarily of the aerial parts of herbaceous monocots and dicots.[8] T. oswaldi fossils are also known from Elandsfontein,[9] where they subsided on diets mainly composed of C3 plants as both browsers and grazers.[10]
