Dietary changes and millet consumption in northern France at the end of Prehistory: Evidence from archaeobotanical and stable isotope data

Diachronic changes of dietary human habits between the Neolithic and the Bronze Age are mainly identified through archaeological artefacts and archaeozoological and archaeobotanical studies. This paper aims to demonstrate the importance of a multi-disciplinary approach for palaeodietary studies and to identify the food changes between Neolithic and Bronze Age human groups in northern France. These changes are probably linked to the introduction of new crops, such as millet, and the use of stable isotope analysis on bones and teeth proves to be an effective method for assessing the role of this specific cereal in the diet and the economy. Stable isotope analyses were performed on bone and tooth collagen and apatite from eight humans and five domestic animals from a Late Bronze Age site (LBA; Barbuise; 15th–13th c. BC; Aube). The studied corpus is compared with isotopic data from human and animal bones from a nearby Neolithic site (Gurgy; 5th mill. BC; Yonne) and regional Neolithic to Iron sites located in northern France. Moreover, Barbuise data are supplemented by information from an important archaeobotanical study carried out on 21 LBA and Early Iron Age sites in the region. Neolithic and LBA human collagen isotopic ratios (δ¹³C, δ¹⁵N) differ statistically, as do those of some animals. Carbon isotopic ratios of human apatite corroborate collagen results indicating the consumption of ¹³C enriched food by LBA humans and animals compared to Neolithic samples. The high number of occurrences of plant remains in the Bronze Age settlements near the site points to the consumption of C₄ plants, such as millet, and would account for these results.     

Osteological and paleodietary investigation of burials from Cova de la Pastora,Alicante, Spain

We present results of osteological and isotopic analyses of human remains from Cova de la Pastora (Alcoi, Alicante, Spain) and discuss the implications in light of a new sequence of radiocarbon dates indicating that the cave was used as a burial site in the Late Neolithic (ca. 3800–3000 cal BC), Chalcolithic (ca. 3000–2500 cal BC), Bell Beaker Transition (Horizonte Campaniforme Transicional - HCT; ca. 2500–2200 cal BC) and the Bronze Age (ca. 2200–1500 cal BC). Similarities in stable isotopic values of C and N indicate little variation in subsistence between men and women, and a similar nutritional base from the Late Neolithic to the Bronze Age. This pattern of stability is augmented by evidence of trauma and disease found on numerous skulls in the collection. Since no clear associations of specific grave goods with certain individuals based on sex or age could be determined, the only suggestion of social inequality lies in the burial practice itself, where certain individuals were interred in caves while others were not.     

The Abandonment of the ZH-Mozartstrasse Early Bronze Age Lake-settlement. GIS Computer Simulation of the Lake-level Fluctuation Hypothesis

Although 'lake-dwellings' existed from the middle of the fifth millennium to the eighth century BC, the entire phenomenon was not a continuous one. There are several periods when the lake shores were abandoned and subsequently reoccupied. The pattern of occupation depends on cultural as well as environmental factors, amongst them the topography and the climate.
Unlike the southern part of the Alps, which seems to have had a more regular occupational pattern throughout the Neolithic and the Bronze Age, the northern Alpine region shows a marked discontinuity along most of the lake shores. Two relevant breaks in lake-shore occupation are known within the northern Alpine region Bronze Age. The first occurred between the 24th and the 20th centuries BC, and the second from the 15th to the middle of the 12th century BC.
The Early Bronze Age site of ZH-Mozartstrasse, situated on the western extreme of Lake Zurich (Switzerland), was abandoned immediately before the beginning of the second major occupational gap in 1503 BC. Two other Early Bronze Age sites namely Bodman-Schachen 1 on Lake Constance, and Arbon-Bleiche 2 on the Swiss part (the southern shore) of the same lake, follow a similar chronology in occupation; and they were both abandoned in the last decade of the 16th century BC.
A possible cause of abandonment is discussed in this paper using an environmental approach related to an abrupt change of climatic conditions which resulted in an increase of the lake levels which forced those prehistoric populations to leave the proximity of the lake shores. Following the implications of pollen and sedimental analyses, the transformation of the Bronze Age landscape caused by the lake water invasion will be simulated with the help of CAD and GIS computer programs.     

DIET AND ENVIRONMENT IN SOUTH‐EASTERN IBERIA DURING THE BRONZE AGE,BASED ON ISOTOPE ANALYSIS OF HUMAN REMAINS

A large sample of human bones from a series of archaeological sites in the south‐eastern Iberian Peninsula was selected for δ¹³C and δ¹⁵N stable isotope analysis. Except for some contrast samples, the remains date from the first half of the second millennium cal BC and are ascribed to the Argar Culture, which developed during the Bronze Age in south‐eastern Iberia. Most authors have considered that this region reached a high degree of social hierarchical organization at this time, as demonstrated by the funerary record, both with regard to the grave goods and to the evidence of physical effort and diseases on the human remains. Results of the isotope analysis revealed the existence of differences among the settlements studied, as well as differences over time within every settlement and among the various individuals tested. Some variances can be assigned to social classes/status and others are linked to chronological factors. In particular, changes in δ¹³C can be explained by the increasing aridity of the first half of the second millennium cal BC, although other causes can be put forward too.     

Modern and early-middle Holocene shells of the freshwater mollusc Unio, from Çatalhöyük in the Konya Basin, Turkey: preliminary palaeoclimatic implications from molluscan isotope data

Carbon and oxygen isotope ratios in the shells of the freshwater Unio mollusc yield information on the isotopic composition of the water in which the shell was formed, which in turn relates to climatic conditions prevailing during the bivalves’ life span. Here we analysed shells from one modern Unio, from a modern lake shore in Anatolia, and 4 subfossil Unio shells from Çatalhöyük (dated between 7200 BC and 5000 BC, Neolithic and Chalcolithic periods). Sequential carbon and oxygen isotope analysis along the surface of the shells provides information on seasonal or shorter-term variability of lake waters during the lifetime of the organisms. δ¹⁸O values of the modern shell are consistent with it being collected from a dammed portion of the Seyhan River that does not undergo intensive summer evaporation. This is in contrast to many of the surface water bodies in Anatolia which suffer extensive evaporation in the arid summers. δ¹⁸O values of the subfossil shells from the Çatalhöyük middens indicate that the bivalves came from lakes which evaporated extensively during the summer months but were replenished by high winter rainfall, suggesting that the subfossil shells lived in relatively small lakes or ponds. Stable isotope analysis along the growth of freshwater bivalves is one of the few methods for investigating seasonal water fluctuations in the past. These results may alter current interpretations on the environment of Çatalhöyük during the Neolithic, although more work is needed to confirm these initial findings.     

Evaluation of radiocarbon dates from the Middle Holocene hunter-gatherer cemetery Khuzhir-Nuge XIV,Lake Baikal,Siberia

A data set of 87 radiocarbon determinations obtained for the Bronze Age Khuzhir-Nuge XIV cemetery in the Cis-Baikal region of Siberia is analyzed from the perspective of data quality and within the local archaeological context. Bone preservation, expressed in terms of collagen yields, is a very important factor affecting both the accuracy and precision of ¹⁴C dates and, therefore, publication of this information should be adopted as a required standard. According to the calibrated high-collagen dates, after a single Serovo interment the cemetery was used continuously by Glazkovo peoples for up to 700 years (∼2700–2000 BC), and 70% of all burials were interred within a relatively short peak period between approximately 2500 and 2300 BC. The extensive radiocarbon data from KN XIV allow for the re-evaluation of existing models and perspectives on the place of the Glazkovo culture within the Cis-Baikal Neolithic and Bronze Age.     

Changing growing conditions for crops during the Near Eastern Bronze Age (3000–1200 BC): the stable carbon isotope evidence

The analysis of carbon isotope discrimination (Δ¹³C) in crop plant remains from seven Bronze Age sites in northern Mesopotamia and the Levant shows clear differences in water availability between the different geographic areas and throughout the different periods (3000–1200 BC). Amongst the different moisture variables modelled precipitation minus evaporation (P-E—using a macrophysical climate model (MCM)) results in very high correlation (0.74) with Δ¹³C values in barley, supporting the significance of climate parameters (effective moisture) in carbon fixation in this species. The comparison of Δ¹³C values of different crops in different periods confirms increased aridity during the Middle Bronze Age (2000–1600 BC), compared to the later Early Bronze Age (2700–2000 BC) particularly in the north-eastern Syrian territory with generally lower Δ¹³C values during the Middle Bronze Age, as has been documented in palaeoclimate proxies, and in agreement with the MCM. Standard deviation in Δ¹³C values from grains or seeds of one species originating from different samples of an individual site may be understood as variability in moisture conditions during the grain-filling period around the considered location. Large standard deviations occur preferably in sites with low mean annual precipitation (e.g. at Emar) and suggest that in these sites, at least some of the crops were irrigated.     

Diversity in foddering strategy and herd management in late Bronze Age Britain: An isotopic investigation of pigs and other fauna from two midden sites

Abstract

Middens of the southern British late Bronze and Iron Age are vast accumulations of cultural debris that can be explained as refuse dumps linked with large periodic feasting events. A distinctive feature of these sites is that their faunal assemblages invariably comprise a considerably higher proportion of pig remains than contemporaneous settlement sites. This paper presents results from a programme of stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope analysis of fauna from two major midden sites, Llanmaes in South Wales and Potterne in Wiltshire. The research aim is to reconstruct husbandry strategies and foddering regimes, particularly concerning pigs, to better understand how the challenges of raising large herds were met. Analysis produced exceptionally wide-ranging results for pigs and other domesticates at both sites, particularly in terms of δ¹⁵N values, demonstrating that diverse foddering strategies were employed. Diversity in the late Bronze Age pig foddering regimes indicates that the Neolithic husbandry practices (focusing on woodland fodder) had not been abandoned, but that new husbandry methods (consumption of household waste) were also being practised, which subsequently became more widely established in the Iron Age. The heterogeneity of signatures suggests that animals may have been husbanded in a piecemeal fashion at a local, household level. This in turn hints that fauna may have been brought to these sites from households across the surrounding landscape, rather than being husbanded by specialist producers in the vicinity of the middens.     

Human subsistence strategy at Liuzhuang site,Henan, China during the proto-Shang culture (∼2000–1600 BC) by stable isotopic analysis

Since the discovery of the proto-Shang culture, created mostly by ancestors of the Shang clan from the late Neolithic Age to the early Shang period (∼2000–1600 BC), the subsistence strategy and lifestyle of humans in China during their movement southwards have been a great focus. Chinese literature and archaeological findings suggest that the proto-Shang societies were composed of different cultural groups and had various subsistence strategies. For example, at the Liuzhuang site, three types of burials, i.e., stone coffin, wooden coffin and earthen shaft-pit, are found. The wooden coffin and earthen shaft-pit burials had been adopted locally in the Central Plains since the Neolithic Age while the stone coffin burials were usually used by people living in Northeast China and had never been found in the Central Plains before. In this study, stable carbon and nitrogen isotopic analyses were performed on human bones from the Liuzhuang site and animal bones from Zhangdeng site in Henan province, China to determine whether different social groups had various accesses to food resources and whether their dietary difference was related to inequality in social status. Humans have mean δ¹³C and δ¹⁵N values of −7.6 ± 0.6‰ and 9.6 ± 1.0‰ (n = 19) respectively, which strongly indicates that humans rely primarily on C₄-based food. The main contribution of C₄-based food in their diet is from millet agriculture or animals that consume millet by-products. The isotopic spacing of carbon and nitrogen isotopic values between pigs and humans, between dogs and humans, and between cattle and humans, all imply that these animals were the main meat resources for humans. Surprisingly, the δ¹³C values and δ¹⁵N values of humans with different types of burials are quite close, indicating that they had equal access to food resources. This result suggests that the proto-Shang humans had adapted to the local subsistence strategy, and the local cultural factors in the Central Plains were very well integrated into proto-Shang culture.     

Investigation of palaeodiet in the North Caucasus (South Russia) Bronze Age using stable isotope analysis and AMS dating of human and animal bones

This paper addresses the question of human palaeodietary adaptation in the Eneolithic and Early Bronze Age periods of the North Caucasus (South Russia) using stable isotope analysis. One of the key questions is the presence of fish in the diet. AMS radiocarbon dating of archaeological bone collagen has also been carried out to investigate potential radiocarbon reservoir effects in human skeletal material as a result of an aquatic diet. A fish component has previously been suggested in the diet of Iron Age and Bronze Age humans across Eurasia by isotopic research and radiocarbon dating of contemporaneous human and animal bones. In the North Caucasus however, isotopic data is scant. This study presents a new set of stable isotopic data from several Early Bronze Age sites, mainly belonging to the Maikop culture of the North Caucasus. The results show that the diversity in climate and environment across the northern Caucasus may be a causal factor for the patterns observed in the stable isotope values of terrestrial herbivores. This affects the isotopic values of the humans consuming them. The differences in δ¹⁵N and δ¹³C ranges of both humans and fauna were found to correlate strongly with geography and climate; the most enriched isotopic values are found in the dry steppe areas to the north. Overall, a relatively high enrichment in δ¹⁵N values of humans compared to local terrestrial herbivores and carnivores was observed. This indicates that aquatic resources were probably part of the Bronze Age diet in the region although the extent of this needs further investigation. The dramatic effect of environmental factors on isotopic values in the Early Bronze Age of the North Caucasus illustrates how confident conclusions cannot be drawn on the basis of a small number of samples from widely differing regions and time periods. Radiocarbon dating can provide a useful tool for identifying dietary derived reservoir ages in humans, potentially caused by a fish diet. With two possible exceptions, the nine human–animal bone pair dated as part of this study showed no consistent indication for a consistent reservoir effect.     

Recent Excavation and Recording at the New Neolithic Rock Art Site of Vallée Aux Noirs,Buthiers (Seine‐et‐Marne,France)

Following the exceptional discovery of Neolithic engravings on a boulder at Vallée aux Noirs in the Fontainebleau forest, south of Paris, an excavation trench was opened in order to access the buried part of the decorated rock panel and explore the stratigraphic context of the artwork. A palaeosol was found two metres below the modern ground level, underneath multiple layers of sterile sandy soil forming a very compact sequence from which only one archaeological artefact was recovered – an Iron Age fibula (c.200–300 BC). Dating of the palaeosol was attempted through two different methods: AMS dates from charcoal suggest a significant span from the Early Bronze Age to the Iron Age, while two more consistent OSL dates point to formation of the palaeosol during the Late Neolithic (3500–3000 cal BC). The entire engraved rock surface (16 m²), including its buried part, was fully recorded. Four main semiotic groups were identified: a typical fifth‐millennium crook‐hafted axe with a ring, two boats with steering oars, and a central, very tall human figure dominating the composition from its 3.5‐metre height.     

Subsistence and the isotopic signature of herding in the Bronze Age Hexi Corridor,NW Gansu,China

Dietary patterns at two Bronze Age sites in the Hexi Corridor are investigated by the analysis of stable carbon and nitrogen isotopes in faunal bone collagen. The findings are compared with archaeobotanical remains from one of the sites which include high proportions of millet (Panicum miliaceum and Setaria italica) as well as the western derived cereals wheat (Triticum aestivum), barley (Hordeum vulgare) and oat (Avena sativa). The isotopic data indicate domestic omnivores (Canis and Sus) had diets dominated by millet. Minimally offset δ¹⁵N values between herbivore and omnivore fauna suggest low consumption of animal protein by omnivores. Diets of herded animal (Bos and Caprinae) included only low proportions of C4 foods, suggesting that these animals were not regularly foddered with millet plants, and that their grazing areas were mostly beyond the agricultural zone. The wide range in δ¹⁵N values amongst herbivore fauna (4.1‰–11.8‰) suggests grazing occurred in a variety of ecological zones, and this would be consistent with the occurrence of long-distance transport of livestock in the region.     

Palaeogeographical reconstructions of Lake Maliq (Korça Basin,Albania) between 14,000 BP and 2000 BP

Since the early 1990s, excavations of a protohistoric lakeside settlement in the Korça basin carried out by a French–Albanian archaeological team have induced geomorphological and palynological studies about the sedimentary records of Lake Maliq. These studies allow us to distinguish a series of centennial-scale high and low lake level events between 4200 and 4000 cal BP (2899–2637 BC/2843–2416 BC) and 2600 cal BP (822–671 BC), probably due to large-scale climate changes (in the Mediterranean basin). In addition, the sediment sequence also gives evidence of a millennial-scale trend of lake level rise. It appears to be an interplay between lake level rises and falls against tectonic subsidence of the basin allowing accommodation space for sediment deposition.The variations of the lake's level and the lake's surface area influenced the development and the abandonment of the nearby lakeside settlements (like the tell of Sovjan). In order to prepare an archaeological survey around the now dried up lake, we made a 3D model of the Holocene deposit from the lake including these lake level results, geomorphological mapping, excavation data, numerous core logs, AMS ¹⁴C dating and SRTM DEM data. The GIS model allowed us to propose four palaeogeographical reconstructions of the extension of Lake Maliq: around 14,000 BP, during the Mesolithic (around 9000 BP – 8781–8542 BC), the Early/Middle Bronze Age transition (around 3800 BP – 2310–2042 BC) and the Iron Age (2600 BP – 822–671 BC). A map of the thickness of the sediments above potential archaeological layers is also proposed.     

Agricultural and household activities in Vestfold,Southeast Norway,as illustrated by pollen data and the charred remains of crops and wild plants

This paper presents and interprets two data sets from Vestfold, Southeast Norway: the pollen record is from a small lake basin, isolated from the sea in Mid Mesolithic (8100–6400 cal BC), and with a record of sediment deposition up to recent time. Charred plant remains from six settlement sites ranging in date from the Late Neolithic (2400–1800 cal BC) to the Merovingian Period (cal AD 570–800). Soil from archaeological contexts that was recovered from several prehistoric settlement features (two- and three-aisled houses, a rock shelter and a pit) has also been investigated. The number and concentrations of identifiable charred macro remains are low from all features except one, but the records contribute to the interpretation of agriculture and wild plant use. Carbonised cereals dated to the Late Neolithic/Early Bronze Age are reported from a two-aisled house. Naked barley was the main cereal identified and a few weed seeds were found with the cereal grains. In a rock shelter nearby, cereals and seeds of flax were found, demonstrating cultivation in the Late Bronze Age. Pollen of ribwort plantain recorded in lake deposits in Nordbytjern, 0·5?km to the southwest, also indicates agricultural activity in the southern part of Vestfold during the Late Bronze Age. Archaeobotanical samples from Early Iron Age houses contained low concentrations of carbonised cereal remains, mainly hulled barley, but also wheat and oat. Seeds/fruits of weeds, plants of moist/wet habitats and grasses increase in abundance from the end of Roman Period. The high concentration of hulled barley found in a pit at the site of Ringdal 13 confirms that hulled barley was a cereal used in the Iron Age. Throughout the Iron Age, cereal pollen has a continuous curve in the Nordbytjern pollen diagram, demonstrating the significance of cereal cultivation in Vestfold. Flax was also cultivated in the vicinity of and probably processed in Nordbytjern. Large numbers of rush seeds and sedge nutlets indicate a possible involvement in basketry and cordage making and/or as animal fodder.     

Reconstruction of diets based on the Δ15N values of individual amino acids at three sites in Sichuan,China

This study analyzes the nitrogen isotope composition of individual amino acids in collagen extracted from human bone samples from the Gaoshan, Yingpanshan, and Xinyicun sites in Sichuan, where the isotope baseline is unavailable or incomparable with the isotopic data derived from human remains. It aims to understand the food compositions of the inhabitants at these sites, spanning the period from the late Neolithic to the middle Bronze Age, during which time agriculture and domestication of animals were introduced to the region and became increasingly important. The δ¹⁵N values of two amino acids, phenylalanine (δ¹⁵N_Phe) and glutamic acid (δ¹⁵N_Glu), indicate that the peoples on the Chengdu Plain mainly consumed terrestrial foods. The contribution of aquatic resources to their diet was limited. A possible explanation for the low dependence on aquatic foods is that the developed agriculture and domestication of animals offered sufficient foods. Such subsistence economies and dietary patterns were shaped in the early Baodun period (ca. 2,500–2000 BCE) at the latest and did not seem to change when transiting to the Bronze Age. This study also assesses the significance of these subsistence practices in supporting the social development of the Chengdu Plain.     

The relative abundance of Onthophagus species in British assemblages of dung beetles as evidence for Holocene climate change

Abstract

The ratio between scarabaeid beetles of the genera Aphodius and Onthophagus in European dung faunas is influenced by summer climate, such that individuals of Aphodius species predominate in Northern Europe but are largely replaced by Onthophagus species in the Mediterranean region. Detailed study of insect assemblages from Neolithic to Saxon date showed a changing ratio between the genera with time. For the Neolithic and most of the Bronze Age, individuals of Onthophagus contributed around 16% of the sum of Aphodius and Onthophagus, but during the Iron Age the proportion of Onthophagus fell to around 3% and remained low. This decline of Onthophagus was probably the result of a slight cooling of mean summer temperature and agricultural intensification. However, the proportion of Onthophagus peaked at over 60% during the middle Bronze Age around 1450 BC. This is argued as reflecting a brief warm episode with mean July temperatures for Central Southern England at least 2°C warmer than at present.     

Neolithic and Bronze-Age Herders of Pupićina Cave,Croatia

Abstract

Pupi?ina Cave (Croatia) preserves an important archaeological sequence spanning 12,000 years. Here we present and discuss the results of extensive excavations in post-Mesolithic deposits.Pupi?ina Cave,located in NE Istria in a region rich in caves and in prehistoric settlement, has well-dated evidence from the Middle Neolithic, Late Neolithic, Middle Bronze Age, Iron Age, and Roman periods. Visitors to the cave in the Middle Neolithic ca. 5500–5000 in calibrated years B.C (cal B.C.) left typical Danilo/Vla?ka pottery and kept herds of sheep and goats during the spring. Mortality profiles suggest that herds were managed for milk production. During the Late Neolithic (ca. 4550–4150 cal B.C.) Hvar pottery appears along with lithic artifacts from great distances (e.g.,Lipari). Herds of sheep and goats were managed for meat as were cattle and pigs. There was a major hiatus in occupation between the Late Neolithic and the Middle Bronze Age. Middle Bronze Age (ca. 1775–1400 cal B.C.) deposits are found only in one large pit. Pottery is dominated by drinking vessels, and faunal use is the same as in the Late Neolithic. The cave was used primarily as an animal pen during the Iron Age (1st millennium B.C.).     

Stable Isotope Record of Human and Sheep Enamel Carbonate from the Ancient Middle Euphrates Valley (Syria)

Stable isotope analyses of human tooth enamel have allowed us to reconstruct the isotope composition of dietary carbon, changes in the oxygen isotope composition of drinking water and the possible migration of humans in ancient Terqa and Tell Masaikh (SE Syria). δ¹⁸O_carbonate values of human tooth enamel from the interval comprising the Neo‐Assyrian to the modern Islamic periods (from 900 BC to AD 1949) generally mirror the isotope composition of Euphrates water, which is believed to have been a major drinking water source. Lower δ¹⁸O_carbonate values of human Bronze Age apatite are linked to a different hydrologic system that was present in the Middle Euphrates valley at that time (2650–1700 BC). Higher δ¹⁸O_carbonate values of some individuals in the Neo‐Assyrian (900–700 BC) and Islamic periods (AD 600–1200) may indicate human migration from the interior of the Near East. Low δ¹³C_carbonate values (−11.3 to −12.4‰) of human tooth enamel from the interval comprising the Early Bronze to the Islamic periods (from 2650 BC to AD 1200) indicate C₃ plants as a predominant source of dietary carbon. Changes in human dietary customs in SE Syria (with inferred usage of C₄ plants) occurred in the modern Islamic period only (AD 1850–1949). Oxygen and carbon isotope data of sheep enamel show the usage of water bodies characterised by an enhanced evaporation rate during the Neo‐Assyrian time (900–700 BC) and grazing sheep herds on drier areas during the Islamic and the modern Islamic periods (after AD 600).

Diet Variability and Stable Isotope Analyses: Looking for Variables Within the Late Neolithic and Iron Age Human Groups from Gougenheim Site and Surrounding Areas (Alsace,France)

Several human groups (from the Neolithic to the Bronze Age) have been analysed in France during the past decade (mainly for C and N stable isotope) as part of research programmes focusing on prehistoric dietary variability. The environment, cultural/social choices or even biological characteristics are among the parameters influencing food acquisition and consumption. This short report presents the first diachronic isotopic results on the palaeodiet in northeastern France. Because of the exceptional archaeological characteristics (human deposits in various positions in pits) of the bone collection from the site of Gougenheim and the surrounding areas (Late Neolithic‐Iron Age, Alsace, France), this assemblage provides a new isotopic dataset to study diet and the potential relationship with social elements or other factors involved in food choices. In order to obtain individual palaeodietary information, carbon and nitrogen stable isotope analyses were performed on 23 adults and 20 immature human bone collagen samples as well as on 25 animal remains. Data were then combined with zooarchaeological and anthropological/archaeological results to reconstruct part of the dietary pattern (i.e. protein consumed) and to detect possible links between the deposit and individual or group social status, defined here by specific mortuary practices. For the Late Neolithic period, isotopic values show, among other things, a wide δ¹³C range within the female human group, which is statistically lower than the male one. Women probably consumed more diversified food sources, suggesting increased residential mobility. Although body deposits point to the presence of two distinct subgroups, no relationship with animal protein intake was identified. Moreover, the comparison with Iron Age individuals brought to light different dietary patterns between the two periods, indicating that stable isotope values were affected throughout time either by increased millet/legume consumption or environmental/anthropic changes.

Environmental Archaeology of Prehistoric NW Crete

Abstract

The occurrence of Central European tree-types no longer growing on Crete indicates that Neolithic and Bronze Age climates were moister than at present. Of equal significance is the appearance of large quantities of olive pollen in Late Neolithic levels, suggesting the practice of olive cultivation. Early Bronze Age levels show a disappearance of some Central European tree pollen and an increase in Mediterranean tree types, suggesting that the climate became somewhat drier. The pollen findings are used along with other environmental and archaeological data to reconstruct landscapes for the Neolithic and Bronze Age of NW Crete.
