Abstract: Queque Cave is located in the Chongzuo Eco-Park(Chongzuo Biodiversity Research Institu-te, Peking University), Jiangzhou District, Chongzuo City, Guangxi Zhuang Autonomous Regio (22°16'22"N,107°30'22"E). The cave occurs in Wuming Mountain, where the Sanhe Cave site is also located(Jin et al.,2009b). The altitude of the entrance is 202 m above sea level, about 7 meters lower than the entrance of the Sanhe Cave. The sediments in the Queque Cave, like those in the Sanhe Cave, accordingly fall into the 5h Early Pleistocene horizon previously revealed in the Chongzuo area(Jin et al.,2009a,b). Four field seasons of excavation at the Queque Cavesite during 2007-2009 unearthed a large number and wide variety of fossils, representing bothlarge and small mammals. Among the taxa that have been recovered are at least two great apes, Gigantopithecus blackhi and Pongo sp, and at least three Old World monkey species. Nearly all of these primate remains from the Queque Cave are gnathodental, including cranial and mandibular fragments but consisting mostly of isolated teeth. In December 2008,a partial macaque skeletonbelonging to an aged male individual and preserving a nearly complete mandible, all 7 cervical vertebrae and 9 thoracic vertebrae, both forelimbs,a part of the right hindlimb, and most of the carpals, tarsals, metapodials and phalanges was unearthed from the sediments of the Queque Cave. This is the most complete skeleton of a fossil macaque so far discovered in China. In this paper, only the mandible is briefly described and compared with the known fossil macaque species in China, due to the scarcity of postcranial fossil material for comparison.A more detailed study of the postcranial macaque bones and the other fossils from the Queque Cave will be published elsewhere.
