Quantifying Ritual Funerary Activity of the Late Prehistoric Southern Kanas Region (Xinjiang, China)

Identifying peaks in anthropogenic activity in a landscape is an important starting point for understanding past social dynamics in the longue durée. Through intensive surveys and remote sensing surveys of the Heiliutan Basin (Heiliutan Dacaoyuan 黑流滩大草原) in the southern Kanas Region (Kanasi 喀纳斯), Xinjiang, China, a high-resolution dataset for over 4000 years of material culture is established. The complete coverage of the area of interest allows for the quantification of ritual funerary activity based on the number of constructed monuments per century. The data show that the intensity of ritual funerary activity was very low and only left marginal traces in the landscape from the Eneolithic Age to the Late Bronze Age. During the Early Iron Age (ca. 850–200 B.C.E.), the basin became a center for construction of burials for social elites of nomadic tribes and the area was rapidly transformed into a landscape of the dead. The Late Iron Age (starting ≈200 B.C.E.) saw a decline of ritual funerary activities in the basin as it became an unimportant side scene to the cultural developments of the wider region

The Potential of New LiDAR Datasets for Archaeology in Switzerland

LiDAR and its derived elevation models have revolutionized archaeological research in forested areas around the globe. Almost a third of Switzerland is covered in forests. The number of archaeological sites recorded in forests in Switzerland is, however, limited. Given these circumstances, it is surprising how underutilized LiDAR data are in archaeological research in the country. As the Federal Office of Topography swisstopo is finalizing the acquisition of new LiDAR datasets, increasing the covered area and allowing for limited time series analyses, these data should be used to the fullest extent. This article describes the open access datasets and elaborates on their potential for archaeological research and cultural heritage management. By employing LiDAR data on a large scale, Swiss archaeological research would likely substantially increase the number of recorded heritage sites. Additionally, this will have the effect of complementing the palimpsests of past anthropogenic activity throughout the landscape while reducing survey biases in the archaeological record

Comparing analysis of pretreatment methods of wood and bone materials for the chronology of peripheral burials at Tunnug 1, Tuva Republic, Russia

Nine burials from Tunnug 1 site in Tuva Republic, which contained human and animal bones as well as remains of wood, were chosen for intercomparison study of preparation methods. Nine human bones, nine animal bones and 11 pieces of wood were prepared. Gelatin extracted from bones was purified using the UF method but the extraction from bones was modified with respect to acid and base treatment. Wood samples were treated as whole using acid-base-acid and cellulose was extracted for comparison. The results confirmed a highly consistent chronology of the sites centered at 200–400 CE, however, a few bones resulted in an offset between ages obtained by different methods. The extraction of cellulose was limited due to the poor preservation of wood. Our results highlight problems of dating poorly preserved bones and wood

The polymorphism and tradition of funerary practices of medieval Turks in light of new findings from Tuva Republic.

The medieval Turks of the eastern Asian steppe are known for funerary finds exalting horsemanship and military heroism that thrived on intertribal warfare. Existing bodies of research on various categories of objects-which include architecture, stelae, grave goods and inhumations-are in depth but highly regionalized. As a result, our understanding of the archaeological culture of the Turks on a spatio-temporal scale commensurate with territorial shifts in their political dominion throughout the period of the Turk khaganates (mid-6th to mid-8th centuries CE) remains disjunct. The present paper addresses this problem of disparate data. We present a synthesis of the archaeological research of medieval Turks spanning Mongolia, southern Siberia, and Xinjiang in view of results of the excavation of medieval burials at Tunnug 1 in Tuva Republic-where Turkic remains are dispersed and not easily distinguishable from other funerary cultures of connecting time periods. We argue that Turkic funerary culture can be better characterized as polymorphic-the presence of different regional amalgams of burial traditions. The horse-and-human burials and commemorative ogradka known to be quintessentially Turkic are but one of the more dominant amalgams. This pattern of differential practices is congruent with the history of medieval Turks evolving as peoples of mixed lineages and political groupings, rather than people of a unitary culture

Deep learning reveals extent of Archaic Native American shell-ring building practices

In the mid-Holocene (5000 - 3000 cal B.P.), Native American groups constructed shell rings, a type of circular midden, in coastal areas of the American Southeast. These deposits provide important insights into Native American socioeconomic organization but are also quite rare: only about 50 such rings have been documented to date. Recent work using automated LiDAR analysis demonstrates that many more shell rings likely exist than are currently recorded in state archaeological databases. Here, we use deep learning, a form of machine intelligence, to detect shell ring deposits and identify their geographic range in LiDAR data from South Carolina. We corroborate our results using synthetic aperture radar (SAR), multispectral data, and a random forest analysis. We conclude that a greater number of shell rings exist and that their distribution expanded further north than currently documented. Our evidence suggests that ring-construction was a more widespread and common practice during the mid-Holocene

Identifying seasonal settlement sites and land use continuity in the prehistoric southern Siberian steppe – Zhelvak 5 (Tuva)

The identification of camp sites of Iron Age cultures on the Eurasian steppes has long been a problem as the traces of seasonal settlements are faint and often destroyed by agricultural activities. Recent research has found increasing evidence for less mobility and a larger role farming played in the mixed and locally adapted economies of peoples on the steppes. Here we present the results of the investigation of a settlement from the Uyuk Valley and contextualize it with data for seasonal camp sites and settlements in Iron Age South Siberia. Contrary to the long-held beliefs that Iron Age herding societies were truly nomadic and did not establish permanent settlements, archaeological research in South Siberia is gradually starting to reveal a different picture. Remote sensing and on-ground surveys uncovered six Scythian-period settlement sites in Tuva occupying southern hill slopes in sheltered topographic settings. Excavations at Zhelvak 5 revealed a stratified site with materials from the Bronze Age to the Late Iron Age and beyond. The archaeological material speaks towards continuity of economic exploitation of this landscape and the establishment of seasonal camp sites in the same place over a prolonged period of time

The Kokel of Southern Siberia: New data on a post-Xiongnu material culture

From the end of the Xiongnu Empire to the establishment of the first Turkic Khaganate, the territory of Southern Siberia sees the emergence of distinctive local material cultures. The Kokel culture is essentially unknown in the international English-language literature even though archaeological sites pertaining to this material culture are among the most common in Tuva (Southern Siberia). This makes them important for the understanding aspects of the sociocultural dynamics following the collapse of the first “steppe empire”. Here we present the results of the study of a Kokel funerary site recently excavated near the Early Iron Age kurgan Tunnug 1 and discuss the data in the context of the available Soviet and Russian literature. The Kokel culture substantially differs from the material culture of the Xiongnu and has to be seen as a largely independent cultural entity of small tribal groups without a pronounced social hierarchy engaging in frequent violent local conflict

Exploiting satellite SAR for archaeological prospection and heritage site protection

Optical and Synthetic Aperture Radar (SAR) remote sensing has a long history of use and reached a good level of maturity in archaeological and cultural heritage applications, yet further advances are viable through the exploitation of novel sensor data and imaging modes, big data and high-performance computing, advanced and automated analysis methods. This paper showcases the main research avenues in this field, with a focus on archaeological prospection and heritage site protection. Six demonstration use-cases with a wealth of heritage asset types (e.g. excavated and still buried archaeological features, standing monuments, natural reserves, burial mounds, paleo-channels) and respective scientific research objectives are presented: the Ostia-Portus area and the wider Province of Rome (Italy), the city of Wuhan and the Jiuzhaigou National Park (China), and the Siberian “Valley of the Kings” (Russia). Input data encompass both archive and newly tasked medium to very high-resolution imagery acquired over the last decade from satellite (e.g. Copernicus Sentinels and ESA Third Party Missions) and aerial (e.g. Unmanned Aerial Vehicles, UAV) platforms, as well as field-based evidence and ground truth, auxiliary topographic data, Digital Elevation Models (DEM), and monitoring data from geodetic campaigns and networks. The novel results achieved for the use-cases contribute to the discussion on the advantages and limitations of optical and SAR-based archaeological and heritage applications aimed to detect buried and sub-surface archaeological assets across rural and semi-vegetated landscapes, identify threats to cultural heritage assets due to ground instability and urban development in large metropolises, and monitor post-disaster impacts in natural reserves

Dining in Tuva: Social correlates of diet and mobility in Southern Siberia during the 2nd–4th centuries CE

OBJECTIVES: Contemporary archeological theory emphasizes the economic and social complexity of Eurasian steppe populations. As a result, old notions of “nomadic” cultures as homogenously mobile and economically simple are now displaced by more nuanced interpretations. Large part of the literature on diet and mobility among Eurasian pastoralists is focused on the Bronze and Iron Ages. The underrepresentation of more recent contexts hampers a full discussion of possible chronological trajectories. In this study we explore diet and mobility at Tunnug1 (Republic of Tuva, 2nd–4th century CE), and test their correlation with social differentiation. MATERIALS AND METHODS: We compare demographic patterns (by age‐at‐death and sex) of carbon, nitrogen, and sulfur stable isotope ratios (δ(13)C, δ(15)N, and δ(34)S) among 65 humans and 12 animals from Tunnug1 using nonparametric tests and Bayesian modeling. We then compare isotopic data with data on perimortal skeletal lesions of anthropic origin and funerary variables. RESULTS: Our analyses show that: (1) diet at Tunnug1 was largely based on C(4) plants (likely millet) and animal proteins; (2) few individuals were nonlocals, although their geographic origin remains unclarified; (3) no differences in diet separates individuals based on sex and funerary treatment. In contrast, individuals with perimortal lesions show carbon and nitrogen stable isotope ratios consistent with a diet incorporating a lower consumption of millet and animal proteins. DISCUSSION: Our results confirm the previously described socioeconomic variability of steppe populations, providing at the same time new data about the economic importance of millet in Southern Siberia during the early centuries CE
