Partial Maxilla and Mandible from Bone Clones® Male Sumatran Orangutan Skull.
The frugivorous (fruit-eating) orangutan has a dental formula 2/2, 1/1, 2/2, 3/3. While humans and our primate cousins share the same amount of teeth, our maxilla and mandibles are shaped differently. Gorillas, chimpanzees and orangutans have much larger teeth and therefore need more room for them in their mouth. In these animals, the shape of the rows of teeth is rectangular, whereas in humans it is "U" shaped.
