Arboreal quadruped: europe middle to late miocene. It is believed to be the ancestor of the orangutan. Ouranopithecus 5-y molars and thick tooth enamel, like humans. Afropithecus early miocene: gigantopichecus late miocene, their dentition is just like ours, orangutans split off earlier, ape hominid split.
