Mandrills and baboons are monkeys; the rest of the species on this list are apes. Typically, Old World monkeys (paleotropical) are larger than New World monkeys (neotropical); the reasons for this are not entirely understood but several hypotheses have been generated. [3]
Baboons are among the largest non-hominoid primates and have existed for at least two million years. Baboons vary in size and weight depending on the species. The smallest, the Kinda baboon , is 50 cm (20 in) in length and weighs only 14 kg (31 lb), while the largest, the chacma baboon , is up to 120 cm (47 in) in length and weighs 40 kg (88 lb).
The largest known Old World monkey is the prehistoric baboon, with a male specimen of Dinopithecus projected to weigh an average of 46 kg (101 lb) and up to 57 kg (126 lb). [221] It exceeds the maximum weight record of the chacma baboon, the largest extant baboon.
The largest of the Old World monkeys is the mandrill (Mandrillus sphinx) with large males being up to 50 kg (110 lb), 90 cm (3.0 ft) long and 50 cm (20 in) at the shoulders. [106] The prehistoric baboon Dinopithecus grew even larger than modern mandrills, weighing as much as a grown man.
