In recent years, the origin and evolution of modern human behaviors have become a common topic of research in Paleolithic archaeology. One important part of modern human behavior, blade technology, was once thought to be unique to modern humans. Recent studies have suggested that variations in blade technology do not fully correspond to modern populations. However, the standardization, diversity, discontinuity in terms of time distribution, and differences in spatial distribution of blade technology give it an important role in discussions of modes of adaptation, diffusion of technology, and population migration of hominins. By categorizing the major blade assemblages in China, we show that there were two blade reduction methods in northern China: the Levallois method and the prismatic method. Dating back 30000–40000 years, the Levallois and prismatic blade method combined to form the characteristics of the early stage of the Upper Paleolithic. Artifacts bearing such characteristics are located in Northwest China, Northeast China, and the Qinghai-Tibet Plateau. The unearthed blades are similar in technological organization and are connected geographically with those discovered in Siberia and Mongolia, which also indicates a distinct border from those discovered in northern China. This fact is suggestive of population immigration. About 25000–29000 years ago, a combination of prismatic blades and microblades was developed in the hinterland of China; however whether it can be regarded as the representative of population migration or only a technological adaption remains undetermined. We suggest that the system of production of different blades should be distinguished in the study of blade assemblages and that different blade methods should not be integrated into a single technical system to discuss technology diffusion and population dispersal. © 2016 Science China Press and Springer-Verlag Berlin Heidelberg

Two exceptionally well-preserved specimens of "Zangerlia" neimongolensis provide additional information on the structure of the skull, shell and limbs of this taxon. These specimens show that the carapace is more similar to that of Hanbogdemys than was previously recognized. A PAUP analysis results in a single most parsimonious cladogram in which the type species of Zangerlia, Zangerlia testudinimorpha is separated from other species that have been included in that genus while " Z." neimongolensis, " Zangerlia" ukaachelys and " Zangerlia" dzamynchondi and Jiangxichelys are grouped together. Both specimens are exceptional in being preserved in a life-like position: one is preserved with the skull in a retracted position; the other with the head and left forelimb both protracted and in a raised position. These positions suggest that they were entombed while still alive. Thus these specimens provide additional examples of rapid burial of vertebrates in the Bayan Mandahu locality, most likely from either by sand storms that dumped massive amounts of sand over a short period of time or by collapse of individuals in burrows. © 2015.

Terahertz (THz) spectroscopy and THz imaging techniques are expected to have great potential for the non-invasive analysis of artworks. We have applied THz imaging to analyse the historic mural painting of a Lamaism temple by using a transportable time-domain THz imaging system; such an attempt is the first in the world. The reflection image revealed that there are two orange colours in the painting, although they appear the same to the naked eye. THz imaging can also estimate the depth of cracks. The colours were examined by X-ray fluorescence and Raman spectroscopy, and the results were found to be in good agreement. This work proved that THz imaging can contribute to the non-invasive analysis of cultural heritage.
