Dryopithecus was a genus of apes that is known from Eastern Africa into Eurasia during the late Miocene period. The first species of Dryopithecus was discovered at the site of Saint-Gaudens, Haute-Garonne, France, in 1856.[1] Other dryopithecids have been found in Hungary,[2] Spain,[3] and China.[4]
Like Sivapithecus, Dryopithecus was suspensory, had a large brain, and a delayed development, but, unlike the former, it had a gracile jaw with thinly enameled molars and suspensory forelimbs; Begun 2004 notes that the similarities and differences between them provides insight into the timing and paleogeography of hominid origins and the phylogenetic divide between Asian and Afro-European great apes. [5]
Description
Dryopithecus was about 4 feet tall in body length, and more closely resembled a monkey than a modern ape. The structure of its limbs and wrists show that it walked in a similar way to modern chimpanzees, but that it used the flat of its hands, like a monkey, rather than knuckle-walking, like modern apes.[6] Its face exhibited klinorhynchy, with its face being tilted downwards in profile.
It likely spent most of its life in trees, and was probably a brachiator, similar to modern orangutans and gibbons. Its molars had relatively little enamel, suggesting that it ate soft leaves and fruit, an ideal food for a tree-dwelling animal.[6]
The five-cusp and juvenile[7] fissure pattern of its molar teeth, known as the Y-5 arrangement, is typical of the dryopithecids and of hominoids in general.
