Description

Restoration by Mauricio Antón

Victoriapithecus macinnesi had a dental formula of 2:1:2:3 on both the upper and lower jaws. Its lower molars are bilophodont with low cusps. The canines show sexual dimorphism and the mandible is relatively deep compared to other Old World monkeys. On the forelimbs, the distal end of the humerus shows a narrow articulation and a deep ulnar notch. It had an average body mass of around 7 kg (15 lb)[1] and the volume of its brain was 36 cm3.[2][3]

Range and locomotion

Victoriapithecus macinnesi lived in Africa. The postcranial remains indicate it was likely quadrupedal.[1]
