Developmental Stress and Survival among the Mid Upper Paleolithic Sunghir Children: Dental Enamel Hypoplasias of Sunghir 2 and 3

The Sunghir 2 and 3 late juvenile to early adolescent immature skeletons, from the Mid Upper Paleolithic (Eastern Gravettian) of northern Russia, exhibit several episodes of dental enamel hypoplasias. Those of the older male Sunghir 2 relate principally to a stress episode in the third year post‐natal, although subsequent minor stress episodes may be indicated. They are not accompanied by other marked developmental abnormalities. The younger female Sunghir 3 exhibits at least three episodes of pronounced post‐natal stress through the third to fifth years post‐natal, followed by femoral and tibial growth arrest lines that formed shortly before her death at 9–11 years. These first decade post‐natal stress episodes of Sunghir 3 may be related to the same developmental condition that produced her abnormally bowed femora pre‐natally and/or to continued frailty related to that condition. Surviving these stress episodes for different lengths of time, both Sunghir 2 and 3 were awarded the most elaborate Paleolithic burial known. Copyright © 2011 John Wiley & Sons, Ltd.     

Mobility patterns and core technologies in the Middle Paleolithic of the Levant

Mobility is thought to be a significant source of Middle Paleolithic archaeological variability in the East Mediterranean Levant. However, models of Levantine Middle Paleolithic land-use have historically been based on rare and taphonomically sensitive evidence from a limited number of sites. Because lithic artifacts are the most ubiquitous archaeological remains available to the prehistorian, relationships between stone tool technology and mobility patterns can improve tests of hypotheses about prehistoric land-use strategies. This paper examines variation in Middle Paleolithic mobility strategies in the Levant from the perspective of core technology. A model linking expedient core reduction techniques and decreased mobility is adapted from one developed for late prehistoric contexts in the New World. Incorporating core data from numerous Levantine Middle Paleolithic assemblages, this study tests hypotheses about diachronic change, synchronic geographic variation, and possible hominin behavioral differences in mobility strategies.     

Structured light scanning for high-resolution documentation of in situ archaeological finds

Archaeologists strive to document the process of excavation and discovery as completely as possible. Over the past several decades archaeologists have incorporated a growing number of computerized techniques for documenting archaeological finds. Scanning is one such technique. There are a number of technologies that now allow archaeologists to scan structures, excavation surfaces and in situ artifacts to create high-resolution, 3D data sets. We report here on a trial application of one of these, a structured-light scanner, to create 3D representations of excavated surfaces and associated artifacts at two Middle Paleolithic sites in southwest France. In each instance, surfaces of approximately 2.5 m² were scanned in approximately 1 day. The resulting data sets are very good representations of the originals in terms of colors and spatial details, and as such provided an important piece of archaeological documentation. To use this equipment successfully in the field, however, required solving a number of logistical issues, and the amount of time required to learn to use this equipment was significant. Once these issues are addressed, this technology is appropriate for documenting extraordinary, unique finds where time and costs are offset by the importance of good documentation.     

“The Good,the Bad,and the Ugly”: evaluating the radiocarbon chronology of the middle and late Upper Paleolithic in the Enisei River valley,south-central Siberia

The ¹⁴C record for the Upper Paleolithic in Siberia has remained largely unevaluated and includes good, bad, and ugly dates. Too often researchers accept either all published dates or only those dates that tend to support proposed chronological hypotheses, regardless of sample quality and association. This article systematically evaluates all published ¹⁴C dates (including several newly obtained AMS dates) from middle and late Upper Paleolithic sites in the Enisei River valley of south-central Siberia to establish a reliable chronology for the region and address the tempo of modern human dispersals in Siberia during late Pleistocene times. The revised chronology indicates humans were present before and after the Last Glacial Maximum, but absent during this climatic event. Results also suggest that human population in the region may have increased during the Oldest Dryas.     

Resource intensification in the Late Upper Paleolithic: a view from southern China

Resource intensification is often viewed as a precursor to sedentism and thereby to agriculture. Late Upper Paleolithic sites in China are also seen as important precursors to the beginnings of sedentism and agriculture, but few faunal assemblages have been studied in detail and therefore little is known of pre-Neolithic economies in the region. A large faunal sample from a key site for early pottery and possible rice collection sheds light on subsistence strategies at the end of the Paleolithic. We apply an array of taphonomic analyses to the mammal remains to investigate the extent to which carcasses were processed for within-bone nutrients, which we see as a possible indicator of resource intensification. Determining if this is a regional trend, and/or represents diachronic change in subsistence strategies, will depend on the availability of comparative data in the future.     

Experimental use and quantitative performance analysis of triangular flakes (Levallois points) used as arrowheads

The invention and widespread use of projectile weaponry is a characteristic presumed to exist only with Homo sapiens. However, as finds of wooden material during the early development of projectile weapons are extremely rare, this remains a contentious topic. Recent work has proposed a series of ballistically-significant morphological characteristics of stone points that yield information about their potential use. Here we report on initial experimental approaches to quantifying the performance of relatively simple stone points as arrow armatures. Two experimental trials were performed using a series of 51 Levallois points. The first, against a uniform density target, was designed to give an overall indication of performance. The second, against a simulated animal carcass, demonstrated the durability of these points. The results of this study suggest that small Levallois points could have functioned as arrowheads, albeit ones likely to break after limited use. They also suggest that these points’ penetrating power is strongly controlled by their morphometric characteristics, most notably their perimeter. This latter finding refines a method for assessing hypothetical Paleolithic stone points on the basis of tip cross-sectional area previously proposed by others.     

Upper Paleolithic raw material economies at Üçağızlı cave, Turkey

This paper addresses variation in lithic raw material economy within the early Upper Paleolithic at Üçağızlı cave (south-central Turkey). The stratigraphic sequence documents some 12,000 years of the early Upper Paleolithic, entailing changes in lithic technology, raw material exploitation, and game use. Although the same lithic raw materials were exploited throughout the sequence to make quite similar ranges of products, there are marked changes in the ways raw materials from different source areas were treated, including patterns of transport and raw material consumption. The concept of technological provisioning is used to understand changing strategies for procuring and managing supplies of flint from different source locations. Shifts in raw material economy are argued to represent responses to changes in residential mobility and the scale/duration of occupations at the cave itself: data on cultural features and foraging strategies provide independent evidence for these shifts in land use. Results have implications for more nuanced approaches to investigating of lithic raw material economies and the significance of “raw material transfers.”     

Human ecological niches and ranges during the LGM in Europe derived from an application of eco-cultural niche modeling

We apply eco-cultural niche modeling (ECNM), an heuristic approach adapted from the biodiversity sciences, to identify habitable portions of the European territory for Upper Paleolithic hunter-gatherers during the Last Glacial Maximum (LGM), circumscribe potential geographic extents of the Solutrean and Epigravettian technocomplexes, evaluate environmental and adaptive factors that influenced their distributions, and discuss this method's potential to illuminate past human–environment interaction. Our ECNM approach employed the Genetic Algorithm for Rule-Set Prediction (GARP) and used as input a combination of archaeological and geographic data, in conjunction with high-resolution paleoclimatic simulations for this time frame. The archaeological data consist of geographic coordinates of sites dated by Accelerator Mass Spectrometry to the LGM and attributed to the Solutrean and Epigravettian technocomplexes. The areas predicted by ECNM consistently outline the northern boundary of human presence at 22,000–20,000 cal BP. This boundary is mainly determined by climatic constraints and corresponds well to known southern limits of periglacial environments and permafrost conditions during the LGM. Differences between predicted ecological niches and known ranges of the Solutrean and Epigravettian technocomplexes are interpreted as Solutrean populations being adapted to colder and more humid environments and as reflecting influences of ecological risk on geographic distributions of cultures.
