They are native to Indonesia and Malaysia. Its strong arms are some of the longest out there, reaching over seven feet. Fully …. Primate skulls particular suitable for comparative studies. The laugh of a large male orangutan is a low and highly resonating roaring sound, while that of the females and babies is more of a high-pitched squeak. When in the resting position the hands curve naturally forming a hook that grips to branches keeping them easily in the tree tops. They also are very long and lean. They continue to get larger as the animal gets older. Primates have fingernails and toenails rather than claws. They are primarily arboreal so use their shoulders and arms for movement more than they use their hips and legs. Most of an orangutan’s body is covered in long, shaggy hair. The males are much larger than the females. Orangutans have powerful jaws capable of cracking, crushing, and chewing fibrous foods such as fruit with spiny coverings, nuts, and tree bark. These pads are located between the eyes and ears and have a similar appearance to a horse with blinders on. It is also believed they serve to attract females for mating purposes. Sivapithecus, fossil primate genus dating from the Miocene Epoch (23.7 to 5.3 million years ago) and thought to be the direct ancestor of the orangutan.

When stretched out to the sides, an adult male orangutan’s arms may measure 213 cm (7 ft.) in length. They also have four toes and an opposable big toe. Well, these two facts are not inconsistent: it could be that the last common ancestor of Sivapithecus and Homo sapiens did in fact live in Africa, and its descendants migrated out of the continent during the middle Cenozoic Era.

Their feet grasp branches and serve as an extra support, in addition to their hands, when hanging upside-down. They also have rows of sharp teeth. The foramen magnum is towards the back of the skull in apes, whose posture was not fully upright. The Sumatran orangutan has a thinner coat of hair than the Bornean species. There are also shades of orange as well. This is because orangutans very rarely are found on the ground walking. You will notice that an orangutan has a very large head and a thick neck. Their strong arm muscles enable them to swing from tree to tree and, along with its shoulders, support the weight of their body. Moreover, even without using the thumb, the hand and fingers can grab small objects tightly in a double locked grip. The position of the face in known Sivapithecus appears to be similar to that seen in Pongo . There are many things you will notice when you look at an orangutan anatomy. (It's also possible that the orangutan-like features of Sivapithecus arose via the process of convergent evolution, the tendency of animals in similar ecosystems to evolve similar features). Another significant difference of the species is the shape of their faces. The flanges on their cheeks are mostly made of fatty tissue and then supported by the facial muscles. It isn’t very thick though but enough to help regulate their body temperatures. The templates for the castings were original skulls belonging to the collections of the Johann Wolfgang Goethe University of Frankfurt am Main (chimpanzee) and the Senckenberg Research Institute and Natural History Museum in Frankfurt am Main (orangutan, gorilla). Should they get into a confrontation they will use their powerful arms and legs to fight with. Sivapithecus (Greek for "Siva ape"); pronounced SEE-vah-pith-ECK-us, Middle-Late Miocene (12-7 million years ago), Chimpanzee-like feet; flexible wrists; large canines, Sivapithecus, the Primate Also Known as Ramapithecus, Bob Strauss is a science writer and the author of several books, including "The Big Book of What, How and Why" and "A Field Guide to the Dinosaurs of North America. Their faces are mostly hairless but in the males some facial hair can develop even giving them a mustache around their prominent mouth. Orangutan arms are one and a half times longer than their legs. The males have large flanges that are attractive to females. As males mature, their throat sacs become much larger. As far as females are concerned, they prefer males with them, over those without. Figure 1-4 is a montage of the skulls of a chimpanzee (left) and a human (right). Also unlike the other great apes, the orangutan generally lives a solitary life, the exception being the extended relationship between the mother and its offspring. SeaWorld and Busch Gardens Conservation Fund. Their strong arm muscles enable them to swing from tree to tree and, along with its shoulders, support the weight of their body. The curvature in their toes and fingers makes it easy for them to grip branches in the treetops. This has very little bearing on a lively debate now going on about whether hominids did, indeed, arise in Africa; unfortunately, this scientific dispute has been tainted by some well-founded accusations of racism ("of course" we didn't come from Africa, say some "experts," since Africa is such a backward continent). This can be seen by looking at the back of the skull; human skulls have a rounded braincase that is much larger than that of a chimpanzee, to house their much larger brains. Orangutans share at least 28 physical traits with humans; that’s 26 more than chimps and 21 more than gorillas. Orangutans can hold, eat, and manipulate food using their hands or just their feet. Your contribution will be appreciated to improve our site. Are you wild about whales? Primate skulls particular suitable for comparative studies. This species has an Orangutan-like skull; Skeleton resembles orangutan but lacks suspensory adaptations; Thought to be orangutan ancestor Gigantopithecus This species was the largest primate ever (180-255+kg); Large, round molars w/ stout canines; Probably a bamboo specialist Sivapithecus and Pongo share several derived cranial features including a high degree of prognathism, oval orbits, a narrow nasal aperture, and broad zygomatic arches (Fleagle, 1999). Apes have larger cerebellums than humans, a trait that probably reflects the demands of an arboreal, tree-dwelling lifestyle. By using ThoughtCo, you accept our, Facts About Oreopithecus, the Prehistoric Primate, Prehistoric Primate Pictures and Profiles, The Miocene Epoch (23-5 Million Years Ago). The cerebellum is the part of the brain that controls posture and movement. They are not as strong as a gorilla but are about seven times stronger than a human male. Crazy about roller coasters? Our overarching zoological mission is to foster conservation awareness and to impart action on our park guests to preserve wild animals and wild places. Both species have long and powerful jaws. The muscles and bones in their jaws are strong enough to crack large nuts as well as ripping off tree bark. Wild adult males can weigh up to 200 pounds and have an arm span of over 7 feet. One distinct feature of males is that they have very large cheek flaps. You will notice that orangutans don’t have tails either. S. sivalensis, discovered in northern India and Pakistan in the early 1930's, lived from about nine to eight million years ago; and a third species, S. parvada, discovered on the Indian subcontinent in the 1970's, was significantly bigger than the other two and helped drive home the affinities of Sivapithecus with modern orangutans. Orangutan coloration can vary greatly between dark-brown and pale reddish-orange but is most often reddish-orange in color. Adult females weigh between 30 to 50 kg (66 to 110 lb.) Being arboreal has led to the need for them to have flexible joins and hands and feet that are agile. The males and females are built differently. The legs of orangutans are smaller than their arms because they are not primarily used in swinging and do not support their body weight. This is due to the fact that it is much warmer there. Since orangutans primarily move through the forest using their arms and shoulders as opposed to their legs and hips, their arms are longer than their legs and their shoulders are wider than their hips.
