Derivation and Application of a Food Utility Index (FUI) for European Wild Boar (Sus scrofa L.)

Abstract

A Food Utility Index (FUI) is presented for European wild boar (Sus scrofa L.), derived from the experimental butchery of two individuals of differing ages. The results differ from FUIs produced for other species because of the different conformation of the species. Application of the FUI to the wild boar assemblage from the Mesolithic site of Ringkloster (Denmark) allows increased understanding of field butchery, transport and processing of the animals.     

A Pilot Study in Odontochronology for the Pig Domestication Question in North‐Central China

In this paper, we report results of the pilot study in which we apply skeletochronological analysis of teeth to a collection of modern Chinese wild boar (Sus scrofa) of known age and date of death. This is the first time that odontochronology has been applied to suids in China. This work allowed us to establish parameters for subsequent analysis of a limited number of Neolithic‐aged Sus (wild boar and possible early domesticated pig) samples from Henan Province. The goal of the research is to contribute to the ongoing reconstruction of Neolithic dietary, health and economic patterns along the Yellow River. Our results are encouraging in that regular seasonal growth patterning is observed in the northern control sample, which is from the same region as our archaeological investigation.

A NEW METHOD FOR EXTRACTION,ISOLATION AND TRANSESTERIFICATION OF FREE FATTY ACIDS FROM ARCHAEOLOGICAL POTTERY

This paper presents evidence for increased recovery of organic residues from archaeological pottery through use of a microwave‐assisted liquid chromatography protocol. C_16:0 and C_18:0 saturated fatty acids were obtained from archaeological potsherds recovered from nine Neolithic settlements in the Middle East dating between 4700 and 7300 cal bc , including materials that had not produced evidence for the survival of any lipid species through use of ‘conventional’ solvent extraction techniques. Compound‐specific isotopic analyses of C_16:0 and C_18:0 fatty acids in potsherd extracts subsequently revealed δ¹³C/δ¹²C compositions consistent with modern subcutaneous fats of wild boar and goats pastured on lands adjacent to the Jordan Valley, and residues from a modern pottery vessel used in the manufacturing of butter, cheese and yogurt in central Turkey. These results are presented as an illustration of capabilities of the microwave‐assisted recovery protocol. The reclamation of saturated and unsaturated fatty acids from archaeological pottery fragments recovered from a number of the earliest ceramic horizons in the Middle East is herewith reported, and the extraction methods and instrumental analytical techniques are described.     

Early Neolithic pig domestication at Jiahu,Henan Province,China: clues from molar shape analyses using geometric morphometric approaches

The zooarchaeology of pig domestication in China is a challenging task due to its wild boar ancestors being widespread throughout Eurasia. However using geometric morphometric approaches on molar tooth (M₂), shape and size variations, from modern and Neolithic suids, using Yangshao pigs as a surrogate for the Neolithic domestic form, we have addressed the identification of morphological change during the early step of domestication in three early Neolithic sites where claims of pig domestication have been made. Phenetic relationships here have revealed clear and interpretable phenotypic signatures in the samples of modern and Neolithic pigs; which provide evidence for pig domestication at the site of Jiahu from at least 6600 BC cal., re-establishing the Yellow River region as one of the earliest centre of independent Chinese pig domestication.     

Dental Anomalies in the Mandible of Capra pyrenaica: Presence of Two Permanent Fourth Premolars in a Pleistocene Wild Goat from Arlanpe Cave (Bizkaia,Northern Spain)

In this study, we report a case of duplication of a lower fourth premolar (P₄) on an Iberian wild goat from the archaeological site cave of Arlanpe, (Lemoa, Bizkaia, Northern Spain). The preserved right mandible corpus displays two premolars and the first molar (M₁). Both premolars conform in size and general shape to fourth premolars (P₄) but the medialmost of the two is rotated 90° counterclockwise, and thus, its wear pattern is different. The comparative analysis to other bovids and the relative scarcity of this anomaly compared to other cases of polydontia and hypodontia suggest that it is a developmental defect consisting in the duplication of the tooth germ, and we doubt on the potential of this abnormality as a territorially based indicator of past wild populations as has been previously proposed.

Size and shape of the Eurasian wild boar (Sus scrofa), with a view to the reconstruction of its Holocene history

Abstract

A large assortment of skulls and skeletons of recent wild boar (Sus scrofa) from across the world has been used to collect tooth and bone measurements that can be compared to those from archaeological specimens. The data provide useful information for a reconstruction of the Holocene history of the species. The evidence collected so far highlights the great variability of the species and provides a baseline to be used for the interpretation of ancient material. It is shown that not only the size, but also the shape of teeth and mandibles can help in highlighting patterns of variability in wild boar from different areas. A number of geographic trends are identified in the variation of S. scrofa across its range, mainly concerning the differentiation of insular forms, and the existence of South–North and West–East clines. Other factors such as hybridisation with domestic stock, feralisation and human-induced movement of animals may also play an important role. A comparison with ancient material emphasises the existence of similarities as well as differences between modern and ancient populations. Although some of the geographic trends identified on the basis of the analysis of modern material seem to date back to early Holocene times, the morphological history of the species appears to be complex, and in more than one area fluctuations in body size seem to have occurred.     

Wild Boar (Sus scrofa) Teeth from a Female Burial in Yuzhniy Oleniy Ostrov,Northwestern Russia (c. 6200 cal BC) – Local Rarities or Transported Goods?

Tooth pendants of European elk, Eurasian beaver and brown bear are the most common artefact type in graves at Late Mesolithic Yuzhniy Oleniy Ostrov on Lake Onega, northwestern Russia. In one burial of a 20-35-year-old woman, 18 fragments of wild boar tooth pendants from at least five individuals were found. Wild boar was not a regular part of local fauna in the Mesolithic, and if these wild boars were hunted locally, they were very unusual game. These wild boar tooth pendants may also represent imported goods that came to Onega from a more southern area via exchange. It is also possible that the woman was not local but came from a region where wild boars were abundant and common game for Mesolithic people.     

Possible Wild Boar Management during the Ertebølle Period. A Carbon and Nitrogen Isotope Analysis of Mesolithic Wild Boar from Fannerup F,Denmark

This paper presents a stable isotope and radiocarbon study on a total of 85 samples of wild boar (Sus scrofa), humans (Homo sapiens), dogs (Canis familiaris), red deer (Cervus elaphus) and roe deer (Capreolus capreolus) from four Late Mesolithic sites in Jutland, Denmark. Four of the eight Sus scrofa samples from one site, the shell midden of Fannerup F, show markedly enriched carbon and nitrogen isotope values, indicating a dietary intake of a substantial amount of marine food. In contrast to standard interpretations of Late Mesolithic animal economy, we suggest that the enriched values of Sus scrofa may be an indication of management by Ertebølle groups in the area that facilitated access to substantial amounts of marine foods for these wild boars compared to contemporaneous conspecifics. The ¹⁴C dates of the Sus scrofa range from 5290 to 4335 cal BC, suggesting that the management of Sus scrofa developed independently of contact with Neolithic societies. Although the sample size remains small, the interpretation of Late Mesolithic animal management adds to the growing evidence for political and economic complexity in the Ertebølle culture.     

Foddering by Mongolian pastoralists is recorded in the stable carbon (δC) and nitrogen (δN) isotopes of caprine dentinal collagen

Direct identification of fodder provisioning in individual animals is a previously unexplored area that has important implications for determining animal husbandry strategies in prehistory. In this study, foddering practices are examined in modern domestic and wild caprines from Mongolia (Baga Gazar'in Chuluu) through carbon and nitrogen analyses of bulk sampled dentin collagen in molar teeth. Foddered caprines display significantly different δ¹³C values compared to non-provisioned caprines. This pattern reflects the consumption of C₄ plants year-round by provisioned caprines while non-provisioned caprines ingest C₄ plants only during the summer months. Provisioned caprines also display significantly different nitrogen isotopic values relative to non-provisioned animals. The difference in nitrogen isotopes between wild and foddered animals may be due to increased access in quality graze through foddering by domestic caprines, which results in improved nutrition and extended lactation periods, or enriched δ¹⁵N of fodder plants relative to background flora. Differences in tooth wear between sampled wild and foddered animals may also contribute to the observed δ¹⁵N differences.     

Subsistence continuity,change, and environmental adaptation at the site of Nugljanska,Istria, Croatia

This paper investigates changes in subsistence strategies at the upland cave site of Nugljanska (Croatia) at the end of the last ice age, during a time of rapid sea level rise and changing environment. We analysed the faunal assemblage from archaeological levels spanning the Pleistocene–Holocene transition (15,000–8000 years BP) and evaluated changes in relative abundance of species, measured species diversity, and compared the representation of terrestrial mammal and marine resources. We found a significant shift in the most abundant prey species exploited (from red deer, Cervus, to wild boar, Sus). There was some correlation between dietary diversification and periods of increased moisture availability and the spread of deciduous forest in the area. Our results suggest that there was a continuing reliance on terrestrial resources throughout time and that changes in dietary patterns were likely due to local environmental change and potentially, changing seasonal mobility strategies, at the Pleistocene–Holocene transition.     

Wild at heart: Approaching Pitted Ware identity,economy and cosmology through stable isotopes in skeletal material from the Neolithic site Korsnäs in Eastern Central Sweden

The Middle Neolithic Pitted Ware Culture on the Baltic Sea islands comprised a common identity distinguished, in part, by an almost exclusively marine diet. Based on evidence from the first stable isotope analysis on Pitted Ware skeletal material from the Eastern Central Swedish mainland, we suggest that this identity was shared by PWC groups in the archipelago of the west side of the Baltic. Fifty-six faunal and 26 human bone and dentine samples originating from the Pitted Ware site Korsnäs in Södermanland, Sweden were analysed, and the data clearly shows that the diet of the Korsnäs people was marine, predominantly based on seal. The isotope data further indicate that the pig bones found in large quantities on the site emanate from wild boar rather than domestic pigs. The large representation of pig on several Pitted Ware sites, which cannot be explained in terms of economy, is interpreted as the results of occasional hunting of and ritual feasting on wild boar, indicating that the animal held a prominent position, alongside seal, in the hunting identity and cosmology of the Pitted Ware people. Further, eleven new radiocarbon dates are presented, placing the Korsnäs site, with a large probability, within Middle Neolithic A.     

Combining Odontochronology,Tooth Wear Assessment,and Linear Enamel Hypoplasia (LEH) Recording to Assess Pig Domestication in Neolithic Henan,China

Mandibles of Sus scrofa (wild boar/pig) from ritual pits H160 and H208 of Longshangang, a Late Yangshao Neolithic site in Xichuan County, Henan, were analyzed for evidence of domestication. Three methods of dental analysis were applied: odontochronology, tooth wear assessment, and linear enamel hypoplasia (LEH) recording, which provide age at death, season of kill, and season of birth data. We investigate whether: (i) the LEH height frequencies on the second molars of the mandibles correspond with the possibility of double farrowing and (2) double farrowing is supported by the season of and age at slaughter data. If so, these data suggest a substantial degree of human management of suids at the site. Copyright © 2014 John Wiley & Sons, Ltd.     

RETENTION OF PHOSPHATE IN BURIED CERAMICS: AN ELECTRON MICROBEAM APPROACH

Elevated concentrations of P₂O₅ of 2–12 wt% absolute were observed in the matrices of a small group of ceramics with the electron microprobe. P₂O₅, CaO and FeO^t are enriched towards the surfaces in some cases and elemental correlations suggest precipitation of a crystalline calcium phosphate with a stoichiometry close to CaO · P₂O₅. Scanning electron microscopy with X-ray mapping showed P₂O₅ to be dispersed in the ceramic matrix on a very fine scale, while X-ray diffraction detected no crystalline phosphate. Parallels are drawn with the precipitation of phosphate in the surfaces of weathered glass. It is concluded that the amorphous phases produced on firing behave as chemically active substrates which facilitate the adsorption or precipitation of very fine grained calcium phosphate from the burial environment.     

Exploring subsistence and cultural complexes on the south coast of Papua New Guinea using palaeodietary analyses

We present the results of a palaeodietary study of a skeletal sample (～800–300 BP) from the south coast of Papua New Guinea (Nebira, site ACJ) using multiple stable isotope analysis of bone collagen. The carbon, nitrogen and sulphur stable isotope ratios of 28 individuals (n = 12 males, n = 13 females and n = 3 subadults) suggested the diet at Nebira was based on C₃ plants (likely starchy vegetable staples) and included protein resources from the surrounding forested areas and C₃/C₄ savannah grasslands such as wallaby and other wild animals. Domestic species (e.g. Sus scrofa, Canis familiaris and Gallus gallus) may also have been consumed but could not be differentiated from wild species by stable isotope analysis. There were no significant differences in stable isotope values between males and females, but the δ³⁴S values of the juveniles suggest they may have consumed varied protein resources. The sulphur stable isotope ratios indicate there was no discernable marine component in the diet of any of the individuals from Nebira. The stable isotope results are interpreted within a wider context of Papuan south coast trade and exchange systems in an attempt to understand local interaction in the region.     

Two sides of the same coin—rocks, bones and site function of Picareiro Cave, central Portugal

The issue of site function rarely has been a main focus in the study of Portuguese Upper Paleolithic. This fact may be related to a lack of interest in this research area. More likely, however, it is due to the fact that there are relatively few Paleolithic sites with data that allow a serious study of site function. At Picareiro Cave, central Portugal, there are various data sets from level F/G dated to the latter Magdalenian that are adequate for this type of research. These are habitat structures, lithic artifacts, macro- and mesofauna, as well as 3D location of all artifacts and fauna larger than 1 cm. Based on the interpretation of the analytical results of each data set, it is possible to reconstruct site function of this particular level of Picareiro Cave. The morphology of one of the hearths, being very large in size, with the base prepared and a pavement surrounding it, as well as the condition and diversity of fauna, indicates that it was used for processing the meat of rabbits, red deer, and wild boar, probably through smoking and grilling. All of the evidence from the different types of data (lithic artifacts, habitat structures, use of space, and fauna) indicate that Layers F/G of Picareiro Cave are the result of a specific task, that of processing animal carcasses of rabbits, red deer, and wild boar.     

Mesospheric temperatures and the OH layer height as derived from ground-based lidar and OH1 spectrometry

Night-time mesospheric temperatures were simultaneously determined from the Doppler broadening of the D₂ resonance line of atmospheric sodium excited by a laser and from the rotational distribution of the P₁(1), P₁(3) and P₁(4) lines of the OH(3,1) band by an i.r. spectrometer. Both instruments were located at the Andøya Rocket Range (69°N, 16°E). The mesospheric temperature gradient permits determination of the altitude of the OH¹ emitting layer from a comparison of the equivalent layer temperatures calculated from the height-resolved Na Doppler temperatures with the observed OH¹ rotational temperatures. The altitude of the OH¹ layer maximum is determined with an accuracy of ±4 km. For 3 nights in January 1986 the OH¹ emission layer is found near an altitude of 86 km.     

Aquatic resources in human diet in the Late Mesolithic in Northern France and Luxembourg: insights from carbon,nitrogen and sulphur isotope ratios

We investigated the contribution of freshwater resources to the diet of seven Late Mesolithic hunter-gatherers (ca. 5300–7000 BC) from Northern France and Luxembourg using stable isotope ratios. In addition to the carbon and nitrogen stable isotope ratios (δ¹³C, δ¹⁵N), we explored the potential of the sulphur isotopic ratios (δ³⁴S) to detect and quantify the proportion of protein derived from aquatic foodstuff. In only two sites, animal remains from an associated settlement were available and subsequently examined to decipher the isotopic differential between terrestrial and freshwater resources. The quantification of their relative contribution was simulated using a Bayesian mixing model. The measurements revealed a significant overlap in δ¹³C values between freshwater and terrestrial resources and a large range of δ¹⁵N values for each food category. The δ³⁴S values of the aquatic and terrestrial animals were clearly distinct at the settlement in the Seine valley, while the results on fish from Belgium demonstrated a possible overlap in δ³⁴S values between freshwater and terrestrial resources. Local freshwater ecosystem likely contributed to ca. 30–40 % of the protein in the diet of the individuals found in the Seine settlement. Out of this context, the isotopic signature and thus contribution of the available aquatic foods was difficult to assess. Another potential source of dietary protein is wild boar. Depending on the local context, collagen δ³⁴S values may contribute to better assessment of the relative contribution of freshwater and terrestrial resources.     

Aging mountain gazelle (Gazella gazella): refining methods of tooth eruption and wear and bone fusion

This paper refines current methods for aging mountain gazelle (Gazella gazella), one of the most common species hunted by prehistoric humans in the southern Levant. Most importantly, we present a new tooth wear scheme for aging the lower deciduous fourth premolar (dP₄), the lower permanent molars (M₁, M₂, M₃) and the lower fourth premolar (P₄) of the gazelle. Broader wear stages for complete mandibles and individual teeth and bone fusion stages are also provided. Finally, a comparison of the tooth wear and bone fusion data indicates that the two methods can be linked at the important transition when a gazelle reaches adulthood (ca. 18 months of age). The completion of the fusion of the gazelle skeleton corresponds directly to the replacement of the dP₄ by the P₄ and the beginning of wear of the M₃. The coincidence of these aging indicators allows for direct comparison of gazelle bone fusion and tooth wear data.     

Stable isotope evidence of human diet at the Nukdo shell midden site,South Korea

Carbon and nitrogen stable isotope analysis was undertaken on bone collagen extracted from archaeological human (n = 48) and animal (n = 45) skeletons from the Nukdo site, Location I C, South Korea. This shell midden and grave site is dated from the late Mumun (550–300 BC) to early Iron Age (300 BC-1 AD) periods. The herbivorous mammals fell within the range of C₃ consumers, with average values of δ¹³C = −21.0 ± 0.5‰ and δ¹⁵N = 3.6 ± 0.5‰ for deer (n = 16) and δ¹³C = −20.6 ± 0.5‰ and δ¹⁵N = 4.5 ± 2.0‰ for wild boar (n = 17). Humans from this site averaged δ¹³C = −18.3 ± 0.4‰ and δ¹⁵N = 11.2 ± 0.7‰ for adults (n = 15) and δ¹³C = −18.7 ± 0.7‰ and δ¹⁵N = 12.5 ± 1.1‰ for juveniles (n = 33). These δ¹³C values indicate that there was no significant input of C₄ plants in the human diets and this may be associated with the spread of rice agriculture in the Mumun period. Human bone collagen δ¹³C and δ¹⁵N values indicate that there was some consumption of marine foods, although the main protein sources were from terrestrial foods. The isotope data demonstrate that the humans at Nukdo had mixed diets that included marine and terrestrial protein, including C₃ plants such as rice. Finally, the isotope results from the juveniles indicate that weaning occurred before the age of 1.5 years in this period.     

Chemical characterization of ancient pottery from sudan by x‐ray fluorescence spectrometry (xrf), electron microprobe analyses (empa) and inductively coupled plasma mass spectrometry (ICP–MS)*

Sixty‐four sherds and seven natural clays from prehistoric sites in northwestern Sudan have been submitted to petrological and chemical analysis using XRF spectrometry, EMPA and ICP–MS. According to their texture, the sherds form five different groups. The high contents of P₂O₅ (more than 0.5 wt%) discerned in 19 samples and the variation of the P₂O₅ content in two samples of the same vessel can be explained by post‐depositional processes or by the ancient organic contents (e.g., milk) of the vessel. Chemical classification of the pottery bulk suggests that vessels were made locally, as only sherds from the same area show homogeneity of data.
