Hunter–gatherer responses to environmental change during the Pleistocene–Holocene transition in the southern North Sea basin: Final Palaeolithic–Final Mesolithic land use in northwest Belgium

Situated along the southern fringe of the North Sea basin, northwest Belgium holds great potential for understanding hunter–gatherer responses to environmental change at the Pleistocene–Holocene transition. Recent intensive fieldwork has yielded valuable data on the palaeoenvironment, chronology, and hunter–gatherer mobility and land use in this region. At the Late Glacial/Early Holocene transition this region was comprised of a landscape of coversand ridges and lakes that flanked the northern part of the Scheldt river basin. This landscape was highly productive for hunter–gatherer populations. As the landscape developed in response to the increasing water table caused by the inundation of the North Sea populations responded by changing their forms of mobility and land use. These changes are indicated by the reduction in the number and density of sites, as well as their geographical settings, from the Late Glacial (Federmesser) and Early Mesolithic to the Middle-Final Mesolithic. Late Glacial/Early Mesolithic sites indicate much higher mobility comprised of rapid displacements of camps and re-occupation of the same coversand ridges over long time-spans. Middle/Late Mesolithic sites indicate a reduction in mobility, increasing focus on prolonged riverside settlement, and a more rigid organization of residential sites.

The radiocarbon reservoir effect: new evidence from the cemeteries of the middle and lower Dnieper basin,Ukraine

This paper presents preliminary results of new radiocarbon dating of human, faunal and fish skeletal remains from a number of the cemeteries from the Middle and Lower Dnieper Basin, Ukraine. The results appear to demonstrate the presence of a radiocarbon reservoir effect during the Neolithic–Eneolithic periods, the first time that this has been identified in this region. The data indicate that the radiocarbon reservoir effect is currently only evident during these periods, and not in the earlier Epipalaeolithic–Mesolithic periods, prompting the suggestion that the radiocarbon reservoir effect is associated with elevated fish consumption from the Neolithic period onwards.     

New Insights into Mesolithic Human Diet in the Mediterranean from Stable Isotope Analysis: The Sites of Campu Stefanu and Torre d'Aquila,Corsica

Mesolithic human remains are rare in the archaeological record of the French Mediterranean. Only the island of Corsica has so far produced relatively well‐preserved burials, and recent archaeological excavations have brought to light new Mesolithic human remains. The site of Campu Stefanu , located in Sollacaro in the southeast of the island, contained a collective burial of seven to eight individuals in a previously unobserved funerary context. A re‐evaluation of collections in regional museums yielded the remains from another Mesolithic individual from the site of Torre d 'Aquila , excavated at Pietracorbara, in the northern part of the island, at the beginning of the 1990s. These two discoveries presented the rare opportunity to obtain new radiocarbon dates and paleodietary insights from this crucial time period using stable isotope analysis (δ¹³C, δ¹⁵N) on collagen. From Campu Stefanu, one individual had sufficient collagen preserved for radiocarbon dating, revealing that it is the oldest Mesolithic human known on the island, dated to 10216–9920 cal. BP. At Torre d'Aquila, radiocarbon dates indicate that the individual belonged to a younger Mesolithic phase than Campu Stefanu, dated to 9903–9596 cal. BP. δ¹³C and δ¹⁵N isotope ratios are similar between the Campu Stefanu and Torre d'Aquila individuals and indicate a diet dominated by the consumption of terrestrial animal protein and a lack of marine resources. These findings are in contrast with the previous results from two other Mesolithic individuals from Corsica from the sites of Araguina Sennola and Monte Leone , for which about 25–30% of the consumed proteins came from a marine diet. The dietary variability recorded in Corsica is consistent with results obtained from Mesolithic human remains of Sicily and the Iberian Peninsula. We can hypothesise, that despite the nomadic lifestyle, the distance to the sea played a major role in Mesolithic food choices in Corsica. Copyright © 2016 John Wiley & Sons, Ltd.     

TREGIFFIAN: THE CHRONOLOGY OF AN ENTRANCE GRAVE

The Tregiffian project involved the analysis and dating of the archive from unpublished excavations in the 1960s and 1970s at an entrance grave in Penwith, Cornwall. A major aim of the project was to establish a robust chronological basis for the use of the entrance grave for burial: 10 samples of cremated human bone were submitted for radiocarbon dating and Bayesian modelling undertaken. The modelling indicates that the use of the chamber for burial between began in 1780–1510 BC and ended in 1595–1425 BC. The results are hugely significant as they provide the first modelled dating from a Penwith entrance grave. This paper discusses the results from the radiocarbon dating project and reconsiders entrance graves in the wider context of the Early Bronze Age megalithic tombs which are found around the Irish Sea.

ON THE AGE AND CONTENT OF JAR‐35—A SEALED AND INTACT STORAGE JAR FOUND ON THE SOUTHERN PLATEAU OF QUMRAN*

An intact and sealed storage jar known as Jar‐35 was found in 2004, south of the Qumran settlement. A previous study identified tartrate in the deposit of the jar, indicating the possible past presence of wine ( Buti et al. 2006 ). However, we cannot confirm this finding. Using liquid and gas chromatography with mass spectrometric detection, no trace of tartaric acid or salts thereof could be detected in our samples. We show that the major component of the deposit is gypsum. No other organic compounds were identified with the methods that we have applied. Both radiocarbon dating of charcoal in the deposit and thermoluminescence dating of the ceramic jar show that it dates to the main period of habitation at Qumran (c. 100 bc to ad 70).     

Points in Time: The Mesolithic–Neolithic Transition and the Chronology of Late Rod Microliths in Britain

This paper presents the results of the Bayesian statistical modelling of radiocarbon dates associated with diagnostic late Mesolithic rod microliths from England and Wales. These date estimates are compared with results for the earliest evidence for Neolithic material culture and practices in Britain (Whittle et al. 2011; Griffiths 2011; 2014; forthcoming). The chronology of some rod microlith sites indicates a potential overlap between the earliest Neolithic and latest Mesolithic material culture and practices, in the first three centuries of the fourth millennium cal BC across England and Wales. The locations of late Mesolithic sites suggest regional processes of ‘neolithization’ may have occurred. In the region where we have the best chronological evidence for late Mesolithic sites – in Yorkshire – the location of the very latest Mesolithic sites suggests these lifeways may have persisted in landscapes which had been foci of hunter‐gatherer activity for hundreds of years, and which might have been understood as ‘ancestral’ or ‘persistent’ places.     

A SPATIO‐TEMPORAL KERNEL METHOD FOR MAPPING CHANGES IN PREHISTORIC LAND‐USE PATTERNS

Archaeologists are accustomed to considering both the spatial distributions of sites and the temporal distributions of dates as means of analysing the dynamics of prehistoric societies. However, spatial and temporal approaches have thus far remained largely separate, rather than being combined within a single, unified framework. A formal methodology is outlined that combines univariate kernel density estimation based on radiocarbon dates with bivariate kernel density estimation based on spatial site coordinates; the approach allows archaeologists to arrive at reconstructed land‐use distributions through time that not only correct for the problematic issue of site contemporaneity, but also reflect the continuous nature of the archaeological record. The model is implemented using as a data set a series of sites from the Mesolithic of Atlantic Iberia; the results demonstrate that it is capable of providing key insights into changing patterns of land use that are not apparent from either the temporal or the spatial perspective alone.     

Late Mesolithic burials at Casa Corona (Villena,Spain): direct radiocarbon and palaeodietary evidence of the last forager populations in Eastern Iberia

Current knowledge about the Mesolithic–Neolithic transition in the Central and Western Mediterranean European regions is deeply limited by the paucity of Late Mesolithic human osteological data and the presence of chronological gaps covering several centuries between the last foragers and the first archaeological evidence of farming peoples. In this work, we present new data to fill these gaps. We provide direct AMS radiocarbon dating and carbon (δ¹³C) and nitrogen (δ¹⁵N) stable isotope analysis were carried out on bone collagen samples of two single burials from the recently discovered open-air Late Mesolithic site of Casa Corona (Villena, Spain). The results shed new light on the chronology and subsistence patterns of the last Mesolithic communities in the Central Mediterranean region of the Iberian Peninsula. Radiocarbon results date the human remains and funerary activity of the site to 6059–5849 cal BC, statistically different from other Late Mesolithic sites and the earliest Neolithic contexts, and bridging the 500 yrs chronological gap of the Mesolithic–Neolithic transition from the area. Isotopic evidence shows that diet was based on terrestrial resources despite the proximity to the site of lagoon and marine ecosystems. This and previous isotope studies from the region suggest a lower reliance upon marine resources than for Atlantic and Cantabrian sites, although intra-regional patterns of neighbouring Mesolithic populations exhibit both fully terrestrial diets and diets with significant amounts of aquatic resources in them. We hypothesize that in the Central Mediterranean region of Spain the Late Mesolithic dietary adaptations imposed structural limits on demographic growth of the last foragers and favoured rapid assimilation by the earliest Neolithic populations.     

An interesting case of prehistoric trepanation from Poland: re‐evaluation of the skull from the Franki Suchodolskie site

The skull described here was excavated in Central Poland (archaeological site Franki Suchodolskie) in 1951, and was known as one of the oldest cases of healed trepanation. This skull, with later excavations from the Ukraine (cemeteries of Vasilyevka II and Vasilyevka III), was the basis for dating the beginning of the practice of trepanation in the Mesolithic period. The skull was never comprehensively described and dated, although it was scientifically extremely important. The skull has been reassessed by the authors of this paper has brought thorough verification of the knowledge concerning this excavation. According to radiocarbon analysis it is much younger than previously thought and has now been dated to the Late Neolithic or the Bronze Age. Earlier opinions about the healing and survival after the operation have not been confirmed: the hole in the squama of the frontal bone made by scraping and then by grooving has no evidence of healing. Radiological studies as well as computer tomography indicate lack of any healing processes in the bone tissue around the trepanation opening. The results of the analysis significantly modify ideas regarding the earliest skull operations in Central Europe, and change the time of the first trepanation to the Late Neolithic, as for most of the continent.

Coast–inland mobility and diet in the Danish Mesolithic and Neolithic: evidence from stable isotope values of humans and dogs

Here we present the stable isotope ratios of carbon and nitrogen measured in bone collagen extracted from humans, dogs, herbivores and fish from Mesolithic and Neolithic coastal and inland sites in Denmark. Bones of freshwater fish from several Early Mesolithic lake-side sites have δ¹³C values surprisingly similar to those seen in marine fish. We propose a model, based on δ¹³C and δ¹⁵N, for the correction for both marine and hard water reservoir effect in radiocarbon dates. A strong reliance on aquatic protein is demonstrated for the Mesolithic inhabitants of the region from the middle of the Early Mesolithic onwards. A significant part of the protein in the diets of the dogs and humans from the Middle and Late Mesolithic was of marine origin, even at inland sites. This observation points to a high degree of (seasonal) coast-inland mobility. The isotopic evidence indicates that during the Neolithic small quantities of aquatic foods were still common sources of dietary protein.     

THINKING ABOUT 'STYLE' IN THE 'POST-STYLISTIC ERA': RECONSTRUCTING THE STYLISTIC CONTEXT OF CHAUVET

Summary.   Over the past decade, new radiocarbon dating from several art caves has conflicted with the traditional stylistic sequence of Palaeolithic art. Using Chauvet as a paradigm, some archaeologists have suggested that stylistic approaches to Palaeolithic art should be rejected in favour of more sophisticated methods, such as AMS radiocarbon dating. Contrary to this proposal, we suggest that the high antiquity of the Chauvet paintings (dated to c .32,000 years BP) does not necessarily imply the end of all stylistic approaches to Palaeolithic art. Taking the recent discoveries (2003) at the site of Hohle Fels and the attribution of the Palaeolithic engravings of the cave of l'Aldène to the Aurignacian (2005) into account, we suggest that the Chauvet paintings can be placed within an Aurignacian stylistic context. Throughout this analysis, we propose some critical thoughts on the concept of 'style' and discuss some ways in which stylistic approaches can be used to improve our knowledge of Palaeolithic art.     

X-RAY FLUORESCENCE CHARACTERIZATION OF THE CORONA FERREA*

X-ray fluorescence (XRF) analyses of metals, glasses and enamels from the Corona Ferrea, or Iron Crown, of Monza are reported. The method followed to obtain quantitative analysis of metal alloys was based on comparison with standards and it is framed on the more general problem of XRF quantitative analysis of irregularly shaped objects with a portable instrument. Preliminary radiocarbon dating results are also reported.     

RADIOCARBON DATING ARCHAEOLOGICAL SAMPLES IN THE EASTERN MEDITERRANEAN, 1730 TO 1480 BC: FURTHER EXPLORING THE ATMOSPHERIC RADIOCARBON CALIBRATION RECORD AND THE ARCHAEOLOGICAL IMPLICATIONS*

The East Mediterranean Radiocarbon (Inter‐)Comparison Project (EMRCP) has measured time series of radiocarbon ages for known age samples of German oak (GeO) and for samples from the near‐absolutely placed Gordion juniper dendrochronology from central Anatolia. In this paper, we review the data for the calendar years from 1730 to 1480 bc , relevant in particular to controversy and debate concerning the absolute date of the Minoan eruption of the Santorini (Thera) volcano. We consider the issue of the radiocarbon (¹⁴C) dating of the Santorini eruption, and the problem of how this relates to the archaeological record and historical chronology of Egypt in light of the ¹⁴C data. We find that these ¹⁴C data, and other recent radiocarbon work, provide good grounds to be confident in the possibility of a robust radiocarbon‐based chronology for the eastern Mediterranean. In contrast, as the radiocarbon case becomes stronger, questions must be asked about some archaeological dating: in particular, at the site of Tell el‐Dab‘a in the Nile Delta of Egypt.     

A STATISTICAL APPROACH TO THE CALIBRATION OF FLOATING TREE-RING CHRONOLOGIES USING RADIOCARBON DATES

The bristlecone pine tree-ring calibration of radiocarbon dates, while necessitating changes of up to 700 years in Holocene chronology before 1000 b.c. , offers possibilities of very accurate dating when ¹⁴C determinations from floating tree-ring chronologies are utilized. A statistical approach assuming linear regression is developed and used to position the floating tree-ring chronologies at Swiss neolithic sites, using radiocarbon dates published by Ferguson, Huber and Suess and by Suess. The statistical method gives objective estimated dates with estimates of error related, in a consistent and explicit manner, to the inherent inaccuracies of the radiocarbon dates. Most of the method may readily be tested by standard statistical procedures. For the particular cases considered the assumptions of linearity and parallelism are investigated, and the precision of the estimated dates is comparable with that claimed by Suess and his co-workers. A precise calibration is thus possible without utilizing the short-term fluctuations in the Suess calibration curve. The analysis, while avoiding some assumptions of Suess and his collaborators, offers an explicit procedure for establishing controlled teleconnections with the Ferguson dendrochronology, and supports their emphasis on the importance of radiocarbon dates from floating tree-ring sequences for the construction of precise prehistoric chronologies.     

THERMOLUMINESCENT DATING OF COLOMBIAN POTTERY IN THE YOTOCO STYLE

Two contexts from the Colombian sites, Yotoco Ferry and Moralba, had been linked by archaeological similarities in pottery style, and dated by association with ware from other sites at circaa.d. 1000. However, radiocarbon dating of those contexts set Moralba at circa 800 b.c. , some 2000 yr older than Yotoco Ferry. Thermoluminescent dating of pottery from Yotoco Ferry dated it at circaa.d. 900, and pottery from Moralba was dated at circaa.d. 870. In addition a metal-smelting pottery crucible, thought to be prehispanic, was studied by thermoluminescence and dated, on the contrary, at less than 120 yr old.
