Mesopithecus ("middle monkey" for being between Hylobates and Semnopithecus in build) is an extinct genus of Old World monkey that lived in Europe and Asia 7 to 5 million years ago.[1][2][3] Mesopithecus resembled a modern macaque, with a body length of about 40 centimetres (16 in). It was adapted to both walking and climbing, possessing a slender body with long, muscular limbs and flexible fingers. Its teeth suggest that it primarily ate soft leaves and fruit.[4] It was once thought that these extinct monkeys might be an ancestor of the grey langur, but a more recent study[5] suggests that they are more closely related to the snub-nosed monkeys and doucs.
