Victoriapithecus macinnesi von Koenigswald, 1969 |
Victoriapithecus macinnesi was a primate. [1] It was described from a single fossil specimen, the oldest Old World monkey skull fossil.[2] It was discovered near Lake Victoria in Kenya and is from the middle Miocene and was closely related to the two or three extinct Prohylobates species.[3] v.macinnesi von Koeningswald includes v.Leakeyi von Koeningswald [4]

An average body mass of around 7.0 kilograms. On the forelimbs, the distal end of the humerus shows a narrow articulation and a deep ulnar notch. (Fleagle, 1988). [5] Described as similar to Cercopithecinae (BENEFIT,MCCROSSIN 1991) .[6]

measurements in millimetres
md = mesiodistal length, bl = buccolingual width (across the mesial loph(id) for molars, labiolingual width for incisors)
Has a dental formula of 2:1:2:3 on both the upper and lower, the mandible is relatively deep when compared to other Old World monkeys. This species had lower molars that are bilophodont with low cusps. The canines are gender dimorphic . [5][10][11]
