Taphonomic modifications produced by modern brown bears (Ursus arctos)

Actualism has been a fundamental tool in taphonomy. The knowledge of accumulation patterning of modern faunal allows us to interpret the activity of different actors in the archaeological record and to reconstruct the behaviour of preterit animals and humans in which we are interested. However, until now, there are few works that include bone modifications made by bears amongst those made by carnivores. Most data about bone modifications made by bears have been obtained from the archaeo‐palaeontological record. In most of these assemblages, the presence of bears is related to their period of hibernation. Therefore, in these contexts, the changes documented on recovered bear bones are associated only with cannibalism. In this paper, we present an actualistic study about modifications on bones made by modern brown bears. These animals can cause damage similar to those produced by other large carnivores. Generally, bear activity leaves slight damage, mainly on large‐sized animal bones. However, on bones of small‐sized animals and those of greater fragility, the bears can produce abundant damage. Though not usual, bears can break long bones and consume the complete epiphysis. This study suggests that bears have the potential to be agents of bone modification in fossil assemblages. Consequently, they should be considered as a possible agent of modification of faunal remains in the fossil record. Copyright © 2011 John Wiley & Sons, Ltd.     

Taphonomic studies with wild brown bears (Ursus arctos) in the mountains of northern Spain

In this work we present data obtained from experiments with wild brown bears from the Cantabrian Mountains in northern Spain. Our results show that wild brown bears do not take carcasses to their dens, but can displace them by tens of meters before eating them, and the remains can become dispersed some meters around the place where the carcass is consumed. The long bones of large-sized carcasses show no fractures, but they do show tooth marks (scores, pitting, punctures and furrowing) especially on the cancellous bone of the epiphyses. Ribs and vertebrae show fractures and furrowing. The innominate also shows furrowing on cancellous bone of the ilium and ischium. The results of this study are in agreement with previous work and also shed some light on the behavior of this carnivore in the wild. The data gathered are of great importance when interpreting paleontological and archaeological sites where the bear is a likely taphonomic agent.     

Investigating foetal and perinatal mortality in prehistoric skeletal samples: a case study from a 3000-year-old Pacific Island cemetery site

The Teouma skeletal sample from Vanuatu represents one of the few truly colonising populations in the Pacific Islands. Therefore, investigating the factors that may have affected foetal/infant mortality in this population is potentially important for understanding the success of settlement in this region of the world. We investigate whether stable isotope analyses of carbon and nitrogen in conjunction with skeletal ageing techniques, can aid in identifying whether the subadults from Teouma died before or after birth in an attempt to understand the potential threats to foetal and infant survival. Multiple skeletal ageing methods using diaphyseal lengths were used to age the young subadults (n = 7). Using regression-based skeletal ageing methods, four of the individuals were aged at around full-term gestation (37–42 weeks gestation), while the remaining three individuals died preterm. The isotope analyses did not assist in identifying the individuals that survived post-birth because none of the subadults displayed the 2–3‰ trophic increase in δ¹⁵N values expected for a breastfed infant, probably as a result of their young age. However, all of the foetal/perinatal individuals exhibited higher δ¹⁵N values in their bone collagen compared with the adult females of the sample, with two of the individuals demonstrating unusually high δ¹⁵N values. The δ¹³C values of the foetuses/perinates did not exhibit the same variation. We explore a number of possible explanations for this elevation of perinatal/foetal δ¹⁵N values and tentatively suggest that this is a result of in utero stress as a consequence of chronic maternal ill-health. The osteological and palaeodemographic evidence supports the assertion that females, foetuses and perinates were susceptible to environmental stress within this colonising population, resulting in early death of the perinatal individuals in addition to early terminations of pregnancy or premature birth possibly caused by infectious and/or metabolic diseases.     

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.     

Morphological analysis of Ozarkodina prolata Mawson and Ozarkodina midundenta (Wang & Ziegler) (Emsian conodonts) from South China

Lu, J.-F., November 2015. Morphological analysis of Ozarkodina prolata Mawson and Ozarkodina midundenta (Wang & Ziegler) (Emsian conodonts) from South China. Alcheringa 40, xxx–xxx. ISSN 0311-5518.

Investigations of conodonts from Emsian (Lower Devonian) strata at Bahe, Liujing and Daliantang in Guangxi and Yunnan, South China, provide new data on the morphological variability and phylogenetic affinity of Ozarkodina midundenta, a species initially assigned to Pandorinellina but transferred to Ozarkodina herein. Morphological analysis suggests that O. midundenta probably developed from O. prolata by progressive fusion of denticles in the middle third of the blade above the basal cavity in the Pa element.

The Sheep Project (1): determining skeletal growth,timing of epiphyseal fusion and morphometric variation in unimproved Shetland sheep of known age,sex, castration status and nutrition

The Sheep Project was designed to investigate the effects of castration, breeding age and nutritional plane on bone growth, epiphyseal fusion, tooth eruption and tooth wear in sheep. The project investigates a population of 356 unimproved Shetland sheep skeletons evenly distributed between females bred at different ages, males and castrates, raised on either high or low nutritional planes. This first instalment focuses on two aspects of our larger study, namely bone growth and epiphyseal fusion as affected by sex, castration and nutrition. Nutrition, sex and castration are shown to influence bone growth in ways that are often element-dependant and not consistent through time. We demonstrate that metric variability (variance) is strongest in males, with little difference between females and castrates, and that, in our sample, nutrition has little influence on variance in any sex cohort. Of importance to the development of models of past animal management this study demonstrates that the standard epiphyseal fusion ranges used by zooarchaeologists are too narrow in most instances and do not account for the large variation between sexes or the lesser variation between planes of nutrition. We recommend methods for recognizing castration and the presence of more than one sheep breed, or type, within the zooarchaeological record.     

The Medieval lead-glazed pottery from Nogara (north-east Italy): a multi-methodological study

The present work focuses on the archaeometric characterisation of 10th–11th-century lead-glazed pottery from Nogara (Verona, north-east Italy), with the main aim of defining the production technology of both glaze and clay body, through a multi-methodological approach.     

Painted plaster from Bronze Age Thebes, Boeotia (Greece): a technological study

From the rather difficult excavations that have taken place in Thebes since the beginning of the last century, many fragmentary but often well-preserved paintings on plaster have been unearthed. These belong to several contexts and periods: House of Kadmos (Late Helladic IIIA), Treasury Room (Late Helladic IIIB1) and Oikopedon Spourli (Late Helladic III). Their iconography, style and technology fit well with other paintings from the Late Bronze Age sites found in the vicinity of Thebes (e.g. Gla and Orchomenos). This paper presents a technological study of the Bronze Age painted plaster from Thebes, Greece. The paintings were investigated by means of X-ray diffraction; stereo, reflected light and scanning electron microscopy; some by laser-induced breakdown spectrometry and by micro-Raman spectroscopy, in order to identify the pigments and the composition of the plaster layers, and to determine the painting technique(s) that the artisans may have employed. The plaster layer onto which the paint layer was applied was often the only layer and consisted mainly of calcite, while a clay plaster formed the backing between the lime plaster coat and the actual wall surface. The pigments identified were: yellow ochre, haematite (red), cuprorivaite (Egyptian blue), indigo and possibly riebeckite for blue, charcoal (black), calcite (white), and a combination of black and red for purple. A detailed macroscopic study of the painted surface revealed several features, which indicated that the technique of al fresco painting was employed extensively, a technique already in use since the start of the Late Minoan I phase on Crete. A generally lower level of quality in the appearance of the later paintings (Treasury Room and Oikopedon Spourli) was also noted, but this was not reflected in the materials used or in their overall manipulation.     

Non-ferrous metallurgy from the Phoenician site of La Fonteta (Alicante, Spain): a study of provenance

The lead isotope composition of 22 samples from the excavation of the Phoenician site of La Fonteta (Guardamar del Segura, Alicante, Spain) has been analysed in a preliminary study of their provenance. These materials span chronologically from the first half of the 8th century BC to the middle of the 6th century BC.The samples have been selected to include materials used in lead and silver production, as well as in copper-based metallurgy. Therefore, lead droplets, galena nodules and fragments of litharge have been analysed, together with a fragment of a copper ingot, an object, a melting waste composed of a Cu–Pb alloy, and two fragments of a material that we have provisionally labelled ‘Pb–Cu cupellation debris’.All these materials have been initially analysed by X-Ray Fluorescence-Spectrometry to identify their bulk compositions. Some of them have been also analysed by SEM–EDX and ICP–OES. Subsequently, lead isotope analyses (LIA) have been performed using Thermal Ionization Mass Spectrometry (TIMS). The new LIA data obtained has been compared with published lead isotope data from the Mediterranean area. The identification of different groups suggests a significant complexity of the internal and external trade routes during the Orientalising period. For this reason, the provenance study of these materials is especially important in shedding light on the commercial dynamics that the Phoenicians established with native people to control the raw materials and to commercialise finished products.     

Dama Dentition: A New Tooth Eruption and Wear Method for Assessing the Age of Fallow Deer (Dama dama)

Reliable ageing techniques for wild animals are notoriously challenging to develop because of the scarcity of sizeable collections of known‐age specimens. Without such techniques it is difficult to reconstruct hunting patterns, which is a significant problem for the examination of assemblages from pre‐farming cultures. This paper presents a new method, based on mandibular tooth eruption and wear, for assessing the age of fallow deer. The method was developed from a large collection (n = 156) of known‐age Dama dama specimens, has been blind tested by members of the zooarchaeological community and represents a user‐friendly system with the potential to generate large compatible datasets through which the dynamics of human–Dama relationships can be examined.

Ethnoarchaeological study of phytolith assemblages from an agro-pastoral village in Northern Greece (Sarakini): development and application of a Phytolith Difference Index

Phytolith assemblages are analysed in an ethnographic agro-pastoral community in Northern Greece. A new method for analyzing the data, combined with the concentrations of phytoliths per gram sediment, helps to differentiate diverse uses of space in the village. The Phytolith Difference Index (PDI) contrasts the phytolith assemblages in sediment samples from the region around the village least affected by human activities with those in the village and its immediate surroundings. The PDI reveals that many of the samples are dominated by the input of the stalks of the domestic cereal, rye, which is used for food, animal fodder and roof thatching. The PDI also differentiates between dung from mules or donkeys with dung from free ranging cows and goats. Activity areas analysed include storage areas, stabling areas, animal enclosures, floors from living areas that were repeatedly swept, hearths and open areas between structures. The combined use of the PDI, together with phytolith concentrations and phytolith morphotype analyses, may prove to be useful for deciphering activity areas in archaeological sites of not only agro-pastoralists, but also pastoralists and hunter–gatherers.     

Cribra orbitalia and porotic hyperostosis in a Greek colonial population (5th to 3rd centuries BC) from the Black Sea

Cribra orbitalia and porotic hyperostosis in Greek skeletal remains have typically been attributed to a genetic anaemia, most notably thalassemia due to the presence of endemic malaria in the Mediterranean region. This paper reports the results of an analysis of cribra orbitalia and porotic hyperostosis in a Greek colonial population (5th to 3rd centuries BC) from the Black Sea. Archaeological evidence, stable isotopic data, and other skeletal indicators of physiological stress are examined to determine the most likely cause(s) of these lesions. While the possibility that some of the colonists of Apollonia suffered from thalassemia cannot be entirely discounted, the skeletal evidence examined in this study is not consistent with a diagnosis of thalassemia. We must therefore be cautious in assuming that cribra orbitalia and porotic hyperostosis in Greek skeletal remains, and indeed skeletal remains from any region where malaria was endemic in the past, is always indicative of this condition. Nutritional deficiencies and exposure to infectious diseases probably played an equally, if not more, important role in the development of these lesions.

Manufacturing (co)agglomeration in a transition country: Evidence from Russia

We document the geographic concentration patterns of Russian manufacturing using detailed microgeographic data. About 80% of three-digit industries are significantly agglomerated, and a similar share of three-digit industry pairs is significantly coagglomerated. Industry pairs with stronger buyer–supplier links—as measured using Russian input–output tables—tend to be slightly more coagglomerated. This result is robust to instrumental variable estimation using either Canadian or US instruments. Using Canadian ad valorem transport costs as a proxy for transport costs in Russia, we further find that industries with higher transport costs are more dispersed, and industry pairs with higher transport costs are less coagglomerated.     

Mobility or migration: a case study from the Neolithic settlement of Nieder-Mörlen (Hessen,Germany)

A combination of stable carbon and nitrogen isotope analysis of collagen and radiogenic strontium isotope analysis of tooth enamel was used to investigate diet and mobility at the early Neolithic settlement of Nieder-Mörlen in Germany. The carbon and nitrogen ratios suggest a mixed terrestrial based diet that is consistent with data previously published for early Neolithic sites in Europe. The strontium isotope data indicate a high degree of human mobility with only one individual having an isotope ratio consistent with locally derived strontium. Unusually, a group of non-local juveniles with isotope ratios typical of upland regions is also present at the settlement but there are no adult burials with such values. Whilst transhumance is considered as an explanation, it would not explain why these non-local juveniles lived foreshortened lives and other possible mechanisms are therefore discussed.     

The Temple of Venus (Pompeii): a study of the pigments and painting techniques

We report here on a study of 57 fragments of wall painting excavated from the Temple of Venus (Pompeii). These samples were characterised by a wide range of analytical methods. Data showed that the palette is varied, although not so broad as that found in other buildings in Pompeii, and is consistent with pigments used elsewhere in Pompeii and in the Roman Empire. It is composed of: natural earths, minerals and rare artificial pigments. Paintings are made up of thin paint layers (0.01–0.10 mm thick) strongly adhering to the underlying preparation layer. Nonetheless, in some cases thicker layers (up to 0.40 mm) were recognised, often spread on other previous painting layers. Samples were also compared with the microstratigraphic criteria developed in Piovesan (2009) to distinguish wall painting techniques. This comparison demonstrated that both fresco and lime painting techniques were adopted.     

Evidence of contact between New and Old World: paleoparasitological and food remains study in the Tagus river population of Sarilhos Grandes (Montijo,Portugal)

The period of European maritime expansion that started in the fifteenth century had a great impact on trading, on human migrations and consequently in the dispersion of infectious diseases. Portugal was at the core of this expansion; however, studies about parasitic infections, especially helminths, are lacking. This study aims to help reduce this gap presenting the results of microscopic analysis of soil sediments collected from the São Jorge churchyard of Sarilhos Grandes (Montijo). Consecrated in the fourteenth century AD, it remained as a burial ground until the nineteenth century. Soil samples collected from the pelvic girdle of five adult individuals and samples taken as control were analysed under the microscope after current conventional methodological procedures were undertaken. Eggs from Ascaris lumbricoides were identified. Also eggs of trichostrongyle type species were identified in two individuals and may represent the first report in archaeological European samples. Food remains include potato and rice starches, muscle fibres, bivalves, pollen grains and fungi spores. The stratigraphy interpretation together with potato findings put the oldest skeletons to a chronology around the sixteenth century AD. These results are consistent with historical sources that documented the prominence of Tagus river nearby villages in maritime expansion.     

Spatial variation of biologically available strontium isotopes (Sr/Sr) in an archipelagic setting: a case study from the Caribbean

This paper presents the results of strontium (Sr) isotope analysis of modern and archaeological animal remains and modern plant samples from the Caribbean region. The goal is to assess if patterns of human mobility can be determined from the archaeological record in an archipelagic setting. The range of variability and spatial distribution of biologically available strontium isotope signatures is reported and data evaluated to determine if sufficient heterogeneity exists to permit the identification of mobility despite the presence of potentially large contributions of marine strontium in island and coastal ecosystems. The (is)landscape is divided into several sub-regions based on the age and lithology of underlying geology and the variability of ⁸⁷Sr/⁸⁶Sr ratios is reported as; mean ⁸⁷Sr/⁸⁶Sr ± 2 standard deviations, number of samples: 1) Volcanic and Intrusive rocks (0.7077 ± 0.0019; n = 162); 2) Cretaceous–Miocene Limestone (0.7085 ± 0.0009; n = 50); 3) Pliocene–Quaternary Limestone (0.7091 ± 0.0004; n = 54); 4) Sedimentary Deposits (0.7094 ± 0.0015; n = 16); 5) Metamorphic Deposits (0.7104 ± 0.0014; n = 6). There are substantial differences between expected ⁸⁷Sr/⁸⁶Sr values based on associated geology and measured ⁸⁷Sr/⁸⁶Sr in flora and fauna samples. These differences emphasize the importance of focusing on bioavailable strontium, as opposed to geological proxies, for estimations of Sr isotope ranges, especially in archipelagic environments. While some overlap exists between the ⁸⁷Sr/⁸⁶Sr ranges of certain sub-regions, other sub-regions possessed limited variation and could be distinguished based on strontium isotope data. This spatial patterning of biologically available strontium indicates that strontium isotope analyses can be successfully applied to the archaeological study of human mobility within the Caribbean region.     

Obsidian from Pulo di Molfetta (Bari,Southern Italy): provenance from Lipari and first recognition of a Neolithic sample from Monte Arci (Sardinia)

Twenty-four obsidian artefacts of the Neolithic Age were found at the large karstic doline of Molfetta (near Bari) along the Southern Italian Adriatic coast. Non-destructive chemical analyses of the glass, by SEM-EDS, allowed their source rock regions to be determined. Twenty-three of the studied artefacts had been traded from the island of Lipari. Only one sample had a glass composition and microphenocrysts (biotite, pyroxene and feldspar) that indicate provenance from the Monte Arci area of Sardinia, in particular from the Perdas Urias (SC) outcrops. The attribution of this artefact to Sardinia enlarges the geographical pattern of Monte Arci obsidian exploitation and distribution from island to Southern Italy during the Middle to Late Neolithic.
