| 1 | A newly discovered Gigantopithecus fauna from Sanhe Cave, Chongzuo, Guangxi, South China显示文摘Among the most important faunas in the Late Cenozoic, the Gigantopithecus faunas have received a good deal of attention. The Gigantopithecus fauna recently discovered in Sanhe Cave consists of more than 80 mammal species, including cf. Hominidae, Pongo sp., Hylobates sp., Sinomastodon yangzien-sis, Stegodon preorientalis, Cervavitus fenqii, Dicoryphochoerus ultimus and Sus xiaozhu. It is the southernmost Gigantopithecus fauna found so far in China. Its geological age is estimated to be Early Pleistocene based on the fauna and stratigraphic correlation. The significant increase in the estimated body sizes of Ailuropoda, Gigantopithecus and Tapirus shows that the Sanhe fauna is middle Early Pleistocene, later than those from Wushan and Liucheng (early Early Pleistocene). Paleomagnetic dating of the fossil-bearing strata in Sanhe Cave gives an age of approximately 1.2 Ma. The fauna is characterized by tropical-subtropical forest types, including Pongo sp., Tupaia sp., Ia sp., Typhlomys intermedius, etc., and it lacks Palaearctic types. It is a typical tropical forest fauna, suggesting an en-vironment with a lush forest and a warm and humid climate. The discovery of the Sanhe Gigantopith-ecus fauna is significant for establishing the chronological stages of the Gigantopithecus faunas in China, and for discussing their origin, evolution and dynamics. | JIN ChangZhu QIN DaGong PAN WenShi TANG ZhiLu LIU JinYi WANG Yuan DENG ChengLong ZHANG YingQi DONG Wei TONG HaoWen | 2009 | Chinese Science Bulletin2009，54，5： | 14 |
| 2 | The Homo sapiens Cave hominin site of Mulan Mountain,Jiangzhou District,Chongzuo,Guangxi with emphasis on its age显示文摘One of the most hotly debated and frontal issues in paleoanthropology focuses on the origins of modern humans. Recently, an incomplete hominin mandible with a distinctly weaker mental protuberance than modern human and a great variety of coexisting fossil mammals were unearthed from the Homo sapiens Cave of Mulan Mountain, Chongzuo, Guangxi. The mammalian fauna from the Homo sapiens Cave characterized by the combination of Elephas kiangnanensis, first occurring Elephas maixmus, and Megatapirus augustus, and strikingly different from the Early Pleistocene Gigantopithecus fauna and the Middle Pleistocene Ailuropoda-Stogodon fauna of South China could be regarded as an early representive of the typical Asian elephant fauna. Faunal analysis, biostratigraphic correlation, and, most importantly, U-series dating all consistently support an estimate of ca. 110 ka for the age of the fossil Homo sapiens and coexisting mammalian fauna, that is, the early Late Pleistocene. The fauna is mainly made up of tropical-subtropical elements, but grassland elements have a much greater variety than forest elements, which probably indicates a drier climate at that time. This discovery of early Homo sapiens at the Mulan Mountain will play a significant role in the study of the origin and its environmental background of modern humans. | JIN ChangZhu PAN WenShi ZHANG YingQi CAI YanJun XU QinQi TANG ZhiLu WANG Wei WANG Yuan LIU JinYi QIN DaGong R.

| 3 | Fossil Orangutan-like hominoid teeth from Late Pleistocene human site of Mulanshan cave in Chongzuo of Guangxi and implications on taxonomy and evolution of orangutan显示文摘Fossil records indicate orangutan-like hominoids have been widely distributed in south China during Pleistocene, although currently only surviving in the tropical forests of Kalimantan and Sumatra in Indonesia. This paper describes the recently discovered hominoid fossil teeth from human site of Mulanshan cave in Chongzuo of Guangxi, whose geological age is the Late Pleistocene, about 11000 yeas age based on associated mammal fauna and U-series dating. Compared with those of modern and subfossil orangutans from Indonesia, other fossil great apes from China, the hominoid teeth from Mulanshan cave are orangutan-like, but show somehow different from Indonesia's orangutans, the average sizes of cheek teeth larger and occlusal enamel wrinkles less and simpler. They are classified temporarily as the subspecies of Pongo pygmaeus weidenreichi. Concerning the variations of morphological features and dental sizes of orangutan-like teeth from southern China and neighboring northern Vietnam, different subspecies or species or genus possibly, but the key evidence is necessary to be identified. | ZHAO LingXia WANG CuiBin JIN ChangZhu QIN DaGong PAN WenShi | 2009 | Chinese Science Bulletin2009，54，21： | 1 |
| 4 | Male attacks on infants and infant death during male takeovers in wild white-headed langurs(Trachypithecus leucocephalus)显示文摘Infanticide was first observed in langurs nearly 50 years ago,and this rare phenomenon has been inferred to have either an evolutionarily adaptive function or to be a pathological and non-functional behavior.In this study,we report 5 male takeover events in one-male groups of white-headed langurs in the Nongguan Karst Hills,Guangxi,China from 1998 to 2006.We recorded 13 attacks on 9 infants by extra-group males or new resident males.During the male takeovers,all of the infants younger than 6 months(with an average age of 3.6 months[N=11])in the groups disappeared.The infant death rate during the 4.2 months after takeover by a new male was significantly higher than the infant death rate calculated for most of the year.Older infants that were still nursing(with an average age of 14.1 months[N=7])were often attacked and seriously wounded by the extra-group males or new resident males,but all of them survived.The interbirth intervals of females whose infants were assumed to be killed by males were significantly reduced relative to those of females in groups with stable male tenure(mean=10 months vs 25 months).Our data suggest that males kill unrelated and unweaned infants during the takeover period to decrease the time until the infants’mothers resume fertility.Thus,infanticide would support sexual selection theory in white-headed langurs.The data also show that infanticidal behavior was directed toward the infants,especially those who were still nursing.Female dispersal may function as a counter-strategy to avoid infanticide. | Lijie YIN Tong JIN Kunio WATANABE Dagong QIN Dezhi WANG Wenshi PAN | 2013 | Integrative Zoology2013，8，4： | 0 |
