Tianshanbeilu is the largest Bronze Age site in eastern Xinjiang, China. Stretching across the entire second millennium BC, it performed a prominent role in connecting the Hexi corridor, Central China and the steppe. A further insight into the metallurgical tradition and the metal supply network is of vital importance to improve our understanding of its multi-connected nature. This paper offers a new set of chemical and isotopic data on the copper-based objects at Tianshanbeilu, including alloying elements, trace elements(impurities) and lead isotopes. Combining the concentrations of arsenic and antimony reveals that arsenic was introduced to copper partially due to the use of specific minerals tethrahedrite-tennantite. Lead isotopes demonstrate that multiple sources of copper were employed at Tianshanbeilu and a majority of them are characterized by common lead, which appears rather different from those of the Central Plains and the Hexi corridor, but highly consistent with local ores. Surprisingly, one object at Tianshanbeilu contains the well-known highly radiogenic lead. This object undoubtedly marks the westernmost boundary of the distribution of the highly radiogenic lead. We also anticipate that more lead isotopic analyses in NW China will further contribute to the study of the highly radiogenic lead in Central China.

In this note we report a new sauriurine bird from the Late Jurassic of Liaoning,China: Confuciusornis sanctus. This bird can be morphologically distinguished from the twoinfraclasses in Sauriurae by significant features, such as the presence of horny bill, a pneu-matic foramen at the proximal end of the humerus and extraordinary long ungual phalangeof the first manual digit. It is referred to a new order: Confuciusornithiformes ord. nov..under the subclass of Sauriurae.

A newly discovered Roman funerary monument from ~ipovo mentions a Roman urban settlement in the municipium rank with the name not identified to date apart from the three initial letters--Bal. The deceased was both in military service as a centurion and in civil service as a decurion of the mentioned town. That it was a person of importance is indicated not only by the gravestone inscription but also by the relief depiction of the deceased, shown to be holding a volumen in his hand. Since the monument is chipped and damaged in the upper part, it can only be determined that it was a stela type funerary monument. The main goal of this work is to underline the importance of this monument as a great archaeological treaser, since it is the first written source from Roman period for the town with the three initial letters--Bal, as well as the source for further excavation and the researching of military units of the first word Nova. Two questions will stay open： when the settlement becomes municipium, and the full name of the town.

We present here a pilot study to examine trophic level effects and migration patterns at the middle Shang Dynasty site of Xiaoshuangqiao in Henan Province using δD results combined with δ^13C and δ^15N values. A total of 33 specimens（17 humans, 7 cattle, 5 pigs, 3 sheep, 1 dog） of bone collagen were isotopically analyzed for δ^13C, δ^15N, and dD values. A strong positive correlation（R^2 = 0.94）between mean δ^15N and δD values of herbivores（cattle and sheep）, omnivores（pig）, carnivores（dog）and humans was observed. The δD results were found to increase by -10‰ to 20‰ from herbivores to omnivores to carnivorous, evidence that collagen δD results are a useful indicator for the study of trophic levels and dietary patterns at archaeological sites. The δD results were also used to examine the origins of two different groups of individuals buried at Xiaoshuangqiao. Individuals buried in sacrificial pits of district V had mean δD values（-47.0 ± 2.9‰, n = 11） that were significantly（p =0.049） elevated compared to the people buried in the stratigraphy of district IX（-51.3 ± 3.3‰, n = 3）,indicating that they were ingesting water from different locations. In addition, the D values of the people buried in the stratigraphy were similar to the pigs（-54.5 ± 4.2‰, n = 5） at Xiaoshuangqiao,suggesting that they were most probably of the local population, and that the individuals buried in the sacrificial pits were most possibly from the coast and prisoners of the Dongyi（“东夷”）people. Thus,δD results have the potential to examine human origins and migration patterns and should be increasingly used in conjunction with δ^13C and δ^15N values at archaeological sites.

We compared the pollen assemblages of surface moss samples and corresponding vegetation inventory data from 34 sites in the Huangling region of the central Loess Plateau. Our aims were to determine the characteristics of the pollen assemblages from the deciduous broadleaved forest climax community and its significance in terms of vegetation type and species composition. The pollen assemblages are dominated by woody plants such as Quercus(42% of total terrestrial pollen),Betula(16%) and Pinus(12%), with minor differences between different plant communities. The pollen assemblages of individual sampling sites differed from the vegetation composition within the 0–100 m scope and were more similar to the vegetation coverage within the 0–1000 m scope. This indicates that the surface pollen assemblages mainly reflect the comprehensive information from the vegetation composition of a large area, rather than the vegetation composition close to the sampling site. The contents of Quercus, Betula and Pinus pollen are high, and close to their vegetation coverage; whereas the contents of deciduous broadleaved arbor taxa(such as Malus and Acer) are lower, but their corresponding regional vegetation cover is higher. This suggests that the vegetation information conveyed by poorly-represented pollen taxa should be considered when interpreting stratigraphic pollen assemblages. Using the observed quantitative relationships between pollen and vegetation of the main taxa, we reconstructed the regional vegetation composition in the Gonghai Lake area of the northeastern Loess Plateau during the middle Holocene(7300–5000 yr BP). The results indicated that Quercus-dominated deciduous broadleaved forest climax community developed in the mountains surrounding the lake.

Animal fossils in archaeological sites are closely related to human activities. The environment and human activities, such as hunting-selection, cook process, traditional culture and habits can be partly inferred from the variety of fauna, fragmentation of the bones, and the human marks on bones' sur-faces. So far, researches about marks on fossils are few in China, and are mainly observed directly by eyes. Light Microscopes and Scanning Electron Microscopes are also applied to the observation abroad. These methods could provide us a lot of information, but are mainly confined to 2 dimensions. In this paper, we analyze human marks on the surface of animal fossils through three dimensions re-construction and isoline analysis, which enable us observe and measure in 3 dimensions. This method gives us a lot of information as follows: the formation of the marks, the tools that produced the marks, the cutting edge, movement and micro-abrasion of the tools. Through study of human marks on the surface of animal fossils unearthed from Bailongdong Cave in Yunxi, Hubei Province, we have got the characteristics of the marks, and further deepen cognition of the cutting edge, cutting orientation, cut-ting sequence, as well as micro-abrasion of tools during the formation of these marks. This is the first to use virtual three dimensions reconstruction in studying the human marks on the surface of animal fossils in China.
