A method to assess wear rate in pig teeth from archaeological sites

The recording of age at death is an important aspect of zooarchaeological analysis as it provides evidence about a variety of research questions, spanning from the origins of domestication to husbandry strategies. Age estimation based on tooth eruption and wear is a commonly used method to establish the age at death of archaeological populations. However, this approach has its limitations. It relies on the principle that tooth wear rate is relatively constant in different populations but, since no method has ever been developed to quantify the rate of wear, such an assumption has never been fully verified. As a consequence, the extent to which variable speeds of wear in different populations may affect age estimations is still unknown. To clarify this bias and offer transparency into the issue, the development of a method to assess wear rate in archaeological teeth is of paramount importance. In this paper, we propose a simple system that allows such an assessment to be undertaken. The system has been developed for pig mandibular/lower teeth but can also be extended to other species. The methodology is then tested on several English Late Medieval and Early Modern pig assemblages which represent ideal case studies as they cover a historical period when extensive changes in pig dietary regimes occurred. The evidence reassuringly suggests that differences in wear rates between these periods were not substantial, which bodes well for the comparability of kill-off patterns. However, comparisons with several outgroups indicate that the potential range of wear rates is much greater than attested in our core case study. Wild boars and prehistoric pigs, in particular, appear to wear their molars more slowly. Caution is therefore needed and it is suggested that tooth wear rates (TWR) and average wear rates (AWR) should routinely be calculated when tooth-based age profiles are analysed

Animal husbandry between the Roman times and the High Middle Ages in central Europe : a biometrical analysis of cattle, sheep and pig

This paper presents a meta-analysis of biometrical data of cattle (Bos taurus), sheep (Ovis aries), and pig (Sus domesticus), with a diachronic, long-term approach (first–twelfth centuries AD) and at a large regional scale (Switzerland and adjacent areas of France), with the aim of looking at changes in animal husbandry during the transition between Roman times and the Early Middle Ages. With this in mind, a comprehensive biometrical analysis is carried out, on the basis of the log-ratio technique (or logarithmic size index — LSI). The results show an increase of the size of domesticates during the Late Roman period, as well as a long period of size decrease in the subsequent centuries. The possible reasons behind this size decrease are discussed, focusing on three factors: a genetic change, less direct control over feeding and breeding, and changing patterns of herd sex ratios. We argue that these changes should be seen as an efficient adaptation of animal husbandry strategies to broader social, economic, and political transformations

Chronological characterization of medieval villages in Northern Iberia: A multi-integrated approach

Defining the occupation sequence of medieval rural farming sites in Northern Iberia is complicated, since they feature low density of stratigraphic relationships and few finds and because of the intensive agricultural activities developed there during the last few decades. This paper presents the chronological characterization of the medieval village of Zornoztegi, located in the Basque Country, in the province of Alava. At this site, dwellings extend over an area of approximately two hectares and consist mainly of negative structures excavated in the bedrock. Radiocarbon dating measurements carried out on 32 samples, together with mortar optical microscopic analyses and other information obtained from stratigraphic relationships, changes in the settlement organization and the study of material culture, allowed structuring and characterizing the occupation sequence of the site of Zornoztegi. Furthermore, Bayesian statistics was used to reduce the range of the calibrated dates and to refine the chronology of the sequence

Diet and food strategies in a southern al-Andalusian urban environment during Caliphal period, ecija, Sevilla

The Iberian medieval period is unique in European history due to the widespread socio-cultural changes that took place after the arrival of Arabs, Berbers and Islam in 711 AD. Recently, isotopic research has been insightful on dietary shifts, status, resource availability and the impact of environment. However, there is no published isotopic research exploring these factors in southern Iberian populations, and as the history of this area differs to the northern regions, this leaves a significant lacuna in our knowledge. This research fills this gap via isotopic analysis of human (n = 66) and faunal (n = 13) samples from the 9th to the 13th century Écija, a town renowned for high temperatures and salinity. Stable carbon (δ13C) and nitrogen (δ15N) isotopes were assessed from rib collagen, while carbon (δ13C) values were derived from enamel apatite. Human diet is consistent with C3 plant consumption with a very minor contribution of C4 plants, an interesting feature considering the suitability of Écija to C4 cereal production. δ15N values vary among adults, which may suggest variable animal protein consumption or isotopic variation within animal species due to differences in foddering. Consideration of δ13C collagen and apatite values together may indicate sugarcane consumption, while moderate δ15N values do not suggest a strong aridity or salinity effect. Comparison with other Iberian groups shows similarities relating to time and location rather than by religion, although more multi-isotopic studies combined with zooarchaeology and botany may reveal subtle differences unobservable in carbon and nitrogen collagen studies alone.OLC is funded by Plan Galego I2C mod.B (ED481D 2017/014).

Beyond faith: Biomolecular evidence for changing urban economies in multi‐faith medieval Portugal

During the Middle Ages, Portugal witnessed unprecedented socioeconomic and religious changes under transitioning religious political rule. The implications of changing ruling powers for urban food systems and individual diets in medieval Portugal is poorly understood. This study aimed to elucidate the dietary impact of the Islamic and Christian conquests.info:eu-repo/semantics/publishedVersio

The 'long' 16th century : a key period of animal husbandry change in England

Although many historians have extensively discussed the agricultural history of England between the Late Middle Ages and the Modern Era, this period of crucial changes has received less attention by archaeologists. In this paper, zooarchaeological evidence dated between the Late Middle Ages and the Early Modern period is analysed to investigate changes in animal husbandry during the ‘long’ sixteenth century. The size and shape of the main domestic animals (cattle, sheep, pig and chicken) is explored through biometrical data and discussed in line with evidence of taxonomic frequencies, ageing and sex ratios. Data from 12 sites with relevant chronologies and located in different areas of the country are considered. The results show that, although a remarkable size increase of animals occurred in England throughout the post-medieval period, much of this improvement occurred as early as the sixteenth century. The nature and causes of such improvement are discussed, with the aim of understanding the development of Early Modern farming and the foundations of the so-called Agricultural Revolution

Socio-economic status and religious identity in medieval Iberia: The zooarchaeological evidence

This paper synthesises faunal data from medieval archaeological sites in the Iberian Peninsula, aiming to identify zooarchaeological evidence that can improve our understanding of socio-economic status and cultural identities. The main zooarchaeological indicators for social differentiation are explored: food procurement and cuisine (taking into account different types of sites – high status, urban and rural), and different socio-political systems (Islamic and Christian regions), from a diachronic perspective

Peasant economy in Late Roman Alava: Zooarchaeology of Zomoztegi

Zomoztegi is a rural settlement located in the Alava plateau (Basque Country, Spain), and it was occupied between the Bronze Age and the Late Middle Ages. During a recent archaeological project, a small settlement consisting of two dwellings dated to the 4 th -5 th centuries was found. The archaeological evidence suggests that this site was probably a small rural settlement dependent on a higher rural centre, perhaps a Roman villa. In this paper, the results of the analysis of the animal remains recovered in this chronological phase are shown. The faunal assemblage is one of the biggest analysed samples dated to the 4th-5 th centuries in the Basque Country. The taxonomic composition, the kill-off patterns, the butchery patterns, the body part frequencies and the biometric data constitute good evidence for understanding peasant economy during Late Roman times. Finally, the faunal evidence will be. discussed together with other types of archaeological records for analysing peasant activity in Late Roman Alava

Reprint of: Urban medieval and post-medieval zooarchaeology in the Basque Country: Meat supply and consumption

This paper examines the zooarchaeological evidence from six Basque towns (Bilbao, Vitoria-Gasteiz, SalvatierraeAgurain, Balmaseda, Orduna and Durango), and compares it with historical written sour- ~ ces. The key aims are a better understanding of urban diet, the provisioning of meat to towns, and the relationship between town and country, in the 12the18th centuries. Taxonomic frequencies, kill-off patterns, butchery practices and biometrical data are examined in a diachronic perspective. The results reveal that, although there are some signs of economic specialization, patterns of urban consumption remained fairly stable. It is suggested that the strict taxation and legislation for meat supply and the ownership of livestock by urban elites meant that urban demand for meat was too tightly regulated to bring about substantial changes in the mechanisms of livestock breeding and supply. The economic system appears to have mainly been geared towards the socio-economic needs of the countryside, despite the central role of some of the Basque towns in international trade
