a male Dryopithecus was estimated to be . Dryopithecus teeth are most similar to those of modern chimps. The teeth are small and have a thin enamel layer. Dryopithecus has a slender jaw, indicating it was not well-suited for eating abrasive or hard food. Like modern apes, the males have pronounced canine teeth. The molars are wide, and the premolars wider. It has a wide roof of the mouth, a long muzzle (prognathism), and a large nose which is oriented nearly vertically to the face. In total, the face shows many similarities to the gorilla; since early to middle Miocene African apes do not share such similarities, gorilla-like features likely evolved independently in Dryopithecus rather than as a result of close affinities. The humerus, measuring an approximate , is similar in size and form to the bonobo. Like in bonobos, the shaft bows outward, and the insertion for the triceps and deltoids was poorly developed, suggesting Dryopithecus was not as adept to suspensory behaviour as orangutans. The femoral neck, which connects the femoral head to the femoral shaft, is not very long nor steep; the femoral head is positioned low to the greater trochanter; and the lesser trochanter is positioned more towards the backside. All these characteristics are important in the mobility of the hip joint, and indicate a quadrupedal mode of locomotion rather than suspensory. However, fruit trees in the time and area of the Austrian Dryopithecus were typically high and bore fruit on thinner terminal branches, suggesting suspensory behaviour to reach them. Paleobiology Dryopithecus likely predominantly ate fruit (frugivory), and evidence of cavities on the teeth of the Austrian Dryopithecus indicates a high-sugar diet, likely deriving from ripe fruits and honey. Dental wearing indicates Dryopithecus ate both soft and hard food, which could either indicate they consumed a wide array of different foods, or they ate harder foods as a fallback. Nonetheless, its unspecialized teeth indicate it had a flexible diet, and large body size would have permitted a large gut to aid in the processing of less-digestible food, perhaps stretching to include foods such as leaves (folivory) in times of famine like in modern apes. Unlike modern apes, Dryopithecus likely had a high carbohydrate, low fibre diet. A high-fructose diet is associated with elevated levels of uric acid, which is neutralized by uricase in most animals except great apes. It is thought they stopped producing it by
