Dionysopithecidae

Dionysopithecidae is an extinct family of fossil catarrhines and the earliest known and most primitive members of the Pliopithecoidea superfamily, with fossils in Sihong in China dating to 18 - 17 million years ago for species Dionysopithecus shuangouensis and Platodontopithecus jianghuaiensis.[1]

A single lower molar found in Ban San Klang in Thailand is similar to those found in Sihong but sufficiently different to be considered a different species, Dionysopithecus orientalis.[1]

They are sometimes treated as a subfamily of Pliopithecidae as 'Dionysopithecinae'.[2]
