Paleolithic stone artifacts, including bifacial handaxes, are extensively distributed in the Bose basin, an area of about 800 km 2. Previous surveys and excavations identified about 57 Paleolithic sites in the basin. Unfortunately, the understanding of the basin-scale distribution of Paleolithic sites was still incomplete due to the lack of systematic archaeological field investigations. Thus, from 2009 to 2010, a comprehensive investigation of the distribution of Paleolithic sites across the entire basin was conducted. As a result, 56 new localities were identified, which brought the total number of Paleolithic sites in the basin to 113. These discoveries provide more integrated data on early hominin behavior during the Middle Pleistocene in the basin. In general, the site and artifact densities decline when moving from northwest to southeast along the Youjiang River inside the basin. A total of 747 stone artifacts, including 65 handaxes, were surface collected during these field surveys. Handaxes are found in higher densities in the northwest part of the basin, whereas they are rare in the southeast. Utilized raw materials also vary between the two regions within the basin. © 2011 Elsevier Ltd and INQUA. Source

The Paleolithic stone tool industry from the Bose Basin (Guangxi, China) is best known for the presence of Acheulean-like bifacially and unifacially-worked handaxes found in the same horizon with tektites dated to 803,000 BP. One point that is often not included in discussion of the Bose lithics is the variability in the distribution of sites and artifacts across the basin. This paper reports the results of an analysis of the spatial distribution of the lithics and sites in the Bose Basin based on a multidisciplinary approach utilizing geomorphological observations, Geographic Information Systems, remote sensing, and computer graphics. Analyses include data collected during a comprehensive systematic archaeological field survey conducted in the basin between 2009 and 2010. The results indicate that the density of sites and stone artifacts per site decrease when moving from the northwest to the southeast. Perhaps the most interesting finding is that the handaxes are concentrated in only certain areas of the basin, a pattern similar to the typical western Old World Acheulean, rather than the Oldowan, where the artifact types appear to be more evenly distributed. © 2012 Elsevier Ltd and INQUA.

We present two previously unreported hominin permanent teeth [one right upper second molar (M2), one left lower second molar (m2)] from Lunadong ("dong"="cave"), Guangxi Zhuang Autonomous Region, China. The teeth are important because: 1) they were found in situ; 2) at least one (M2) can be confidently assigned to modern Homo sapiens, while the other (m2) is likely modern H.sapiens; and 3) the teeth can be securely dated between 126.9±1.5ka and 70.2±1.4ka, based on multiple MC-ICP-MS uranium-series dates of associated flowstones in clear stratigraphic context. The Lunadong modern H.sapiens teeth contribute to growing evidence (e.g., Callao Cave, Huanglongdong, Zhirendong) that modern and/or transitional humans were likely in eastern Asia between the crucial 120-50ka time span, a period that some researchers have suggested no hominins were present in the region. © 2014 Elsevier Ltd and INQUA.

Dentognathic remains of Gigantopithecus blacki from the newly discovered Early Pleistocene locality of Yanliang Cave, Guangxi, South China are described. These include an incomplete mandible, only the fourth discovered and the first known from a site other than Liucheng, as well as 25 isolated teeth. Comparisons of the Yanliang mandible show that the best preserved part of the right corpus is morphologically similar to the left side of the Liucheng Mandible III. In addition, the Yanliang mandible and the Liucheng Mandible III share a similar degree and pattern of wear on the premolars and molars. The partially resorbed alveolus for the right M2 in the Yanliang mandible indicates antemortem tooth loss, which is the first record of its kind for Gigantopithecus blacki. Comparisons of the enamel–dentine junction morphology show that the isolated upper premolars from Yanliang are similar to those of Gigantopithecus blacki from Early Pleistocene sites, and differ from the more specialised form from the Middle Pleistocene Hejiang Cave. This supports the biochronological evidence that Yanliang Cave is Early Pleistocene in age. © 2016, © 2015 Taylor & Francis. Source

The Mohui fauna, associated with Gigantopithecus blacki, has been recovered from the Pleistocene karst cave deposit in Bubing Basin, Guangxi, South China. The large-mammalian assemblage derives from 28 species, 15 of which have no historic descendants. Occurrence of some ancient species implies that this fauna is early Early Pleistocene, such as Hystrix magna, Sinomastodon yangziensis, Stegodon huananensis, Ailuropoda microta, Pachycrocuta licenti, Tapirus sanyuanensis, Hespertherium sp., and Dorcabune liuchengense. Comparisons to already-dated early Pleistocene faunas in South China, combined with preliminary paleomagnetic, electron spin resonance (ESR) and U-series analysis of this cave, indicate mammalian fauna age around 1.7 Ma. Comparisons to five faunal assemblages in the same basin show species-level differences in Ailuropoda, Stegodon, Hystrix, Tapirus, and Sus, implying the large-mammal fauna has passed through a slow process of evolution during the Quaternary in East Asia. © 2014 Elsevier Ltd and INQUA.
