Male guinea baboons are not as rigidly dominant as hamadryas baboon males, and unlike female Hamadryas baboons, female guinea baboons exert a more active role in leading the group. [7] Males are also unusually tolerant of one another, and there is very little aggression in this species. Unusually for baboons (and old world monkeys in general ...

The Cercopithecinae are a subfamily of the Old World monkeys, which comprises roughly 71 species, including the baboons, the macaques, and the vervet monkeys.Most cercopithecine monkeys are limited to sub-Saharan Africa, although the macaques range from the far eastern parts of Asia through northern Africa, as well as on Gibraltar.
A skull. The drill is a short-tailed monkey up to 70 cm (28 in) long, similar in appearance to the mandrill, but lacks the bright blue and red on the face of that species. It has high sexual dimorphism in weight, with males weighing up to 20 kg (44 lb) and females up to 12.5 kg (28 lb). [4] A close-up of face. The body is overall a dark grey-brown.
Overall, the skull is similar to that of modern baboons, except that it generally lacks the facial fossae (depressions on the sides of the muzzle and lower jaw) and maxillary ridges (ridges of bone that run along the upper sides of the snout). [2] [4] For these reasons, Dinopithecus is sometimes treated as a subgenus of Papio. [2] [7]
Fossils of various animals have also been found, including those of extinct species of hippo, elephant, zebra, giraffe, and baboon, likely to have been butchered with the aid of the hand axes. [1] [3] In June 2003, a team led by Potts discovered a frontal bone in situ. [8]
Other mammals include roan antelope, Guinea baboon, green monkey, patas monkey, and warthog. Around 330 species of birds have been sighted in the park, notably the Arabian bustard, black crowned crane, Abyssinian ground hornbill (Bucorvus abyssinicus), martial eagle, bateleur (Terathopius ecaudatus), and white-faced duck (Dendrocygna viduata).
Dusky leaf monkeys (Trachypithecus obscurus). Cercopithecoidea is a superfamily of primates.Members of this family are called cercopithecoids, or Old World monkeys, and include baboons, colobuses, guenons, lutungs, macaques, and other types of monkeys.
