Temporal range: 3.3–2 Ma Pliocene
Species: Theropithecus brumpti
T. brumpti was a large, terrestrial monkey, and like most other such animals, was quadrupedal with highly dexterous, manipulative hands. Males grew very large, as a specimen found at Lomekwi, Kenya is estimated to have weighed approximately 43.8 kilograms (96.5 pounds). (In comparison, the male gelada averages around 20 kilograms, 44 pounds). The male was also most likely very colorful, with the female being smaller and less colorful, as the species displayed a high degree of sexual dimorphism. Like most papionins, the male possessed large canine teeth, primarily for display.
T. brumpti was most likely a folivore. Large muscles attached to flaring cheekbones with a long muzzle suggest T. brumpti ate tough vegetation, and was capable of breaking and eating large nuts. These animals, like their modern relatives show adaptations to make precise, strong pincer movements with their thumbs and index figner for gathering particular food items.
This species was largely terrestrial, with the size of adult males making any significant arboreal lifestyle unlikely. The location of T. brumpti finds indicates the species lived in riverine forest habitats. In morphology, it mixed the powerful forea and aft movement of it's limbs with some climbing features, such as mobile shoulder joints.
