Fought under the walls of Bergida: KOCOA analysis of the Roman attack on the Cantabrian oppidum of Monte Bernorio (Spain)

As conflict archaeology has matured as a discipline, there have been calls for more unified analytical techniques. Several researchers advocate the adoption of codified analytical and planning concepts used by the United States Army. One of these concepts, KOCOA Terrain Analysis, shows promise as a locational and analytical aid in archaeological contexts. Defining terrain features are identified and categorized according to well-defined terminology, allowing for a detailed analysis of the effects of terrain on military operations. KOCOA’s structure and codification render the concept transferable between researchers and diachronically across different site types. KOCOA has only rarely been utilized outside the United States and only on historical battlefields. The ongoing archaeological research at the Monte Bernorio oppidum (Palencia, Spain) provides an opportunity to utilize KOCOA in a classical, proto-historical archaeological context.     

The potential of paleoethnobotanical evidence for the study of Teotihuacan foodways

Macro- and microscopic plant remains recovered from excavations at Teotihuacan over several decades contribute to an understanding of the subsistence resources available to the city’s inhabitants. However, associated contextual evidence may be inconclusive regarding the specific uses of the plants in question and, particularly, whether their presence or relative abundance indicates processing and consumption or the consequence of depositional processes. While the analysis of archeological plant remains is necessarily an interdisciplinary endeavor, involving aspects of botany, ecology, ethnography and history among other disciplines, contextual archeological evidence provides the matrix for interpretation. In this paper, we explore direct archeological evidence for plant use, considering the significance of appropriate contextual evidence (e.g., activity areas, associated ceramics, lithics, etc.) and the potential complementary role of analytical techniques such as residue analyses, and carbon isotope signatures in faunal and human osteological remains as well as stratigraphic sediments.     

The Nice Musical Chairs Model: Exploring the Role of Competition and Cooperation Between Farming and Herding in the Formation of Land Use Patterns in Arid Afro-Eurasia

Following a strictly theory-building approach, we developed an agent-based simulation model, the Nice Musical Chairs model, to represent the competition between groups of stakeholders of farming and herding activities in the arid Afro-Eurasia. The model deepens the questions raised by the results of our former model, the Musical Chairs model, and further introduces three socio-economic mechanisms, which modulate the behavior and performance of stakeholders and their groups. First, we define land use pairing as the awarding, regarding productivity, of any direct cooperation between farming and herding within a group. Second, group management is modeled as the prerogative of a group leadership to manage stakeholders to pursue a particular proportion between farming and herding. Third, we introduce restricted access to pasture as the engagement in territorial control of rangelands in opposition to an open access regime. An exhaustive exploration of scenarios and parameters placed the control over rangelands as the most significant factor in the formation of land use patterns, followed by land use management. While the effect of land use pairing is mild in comparison, it is still a significant factor in group selection and thus in the persistence of particular land use patterns in the long run.     

First Evidence of Collective Human Inhumation from the Cardial Neolithic (Cova Bonica,Barcelona, NE Iberian Peninsula)

Excavations at Cova Bonica (Barcelona, Spain) have revealed 98 human remains, grouped into five age clusters and corresponding to a minimum of six non-articulated individuals. The remains are clearly associated with Cardial pottery, lithic artifacts, and ornaments suggesting an Early Neolithic horizon. The radiocarbon dating of three human individuals provides a reliable attribution to this period, with a range between ca. 5470 and 5220 cal b.c., identifying it as one of the few assemblages of human remains directly dated from this period. These remains correspond to a rare collective human inhumation and join a growing body of samples from the Cardial Neolithic, which is providing some of the important sites for the study of population movement and the spread of Neolithization along the western Mediterranean coast.     

Electrochemical Characterization and Dating of Archaeological Leaded Bronze Objects Using the Voltammetry of Immobilized Particles

The application of solid state electrochemistry techniques for the characterization and dating of leaded bronze objects is described. Characteristic voltammetric signatures of copper and lead corrosion products were used as markers of more or less prolonged corrosion periods. The proposed methodology was applied to samples from the Roman archaeological sites of Valeria (Spain) and Gadara (Jordan), Roman and medieval sites in Xàtiva (Spain), and modern statuary exhibited outdoors, on the campus of the Universitat Politècnica of Valencia, Spain, covering a time interval between the fourth to second century bc and the 20th century ad . For such samples, the ratio between the signals for copper and lead corrosion products decreased monotonically with the corrosion time. This variation was modelled on the basis of thermochemical and kinetic considerations, the experimental data being consistent with a potential rate law for the corrosion process.     

Spatial Patterns in the Association between the Prevalence of Asthma and Determinants of Health

The World Health Organization endorses the study of diseases from the perspective of the Determinants of Health (DH), that is, the circumstances in which people are born and raised, the environment in which they grow up and age and their lifestyle. The aim of this study is to analyze the spatial behavior of the prevalence of asthma in Aragon, a Mediterranean region in Spain, under the DH approach. The methodological process entailed building a spatial database collating asthma prevalence as dependent variable, and lifestyle, socioeconomic, and climate indicators as explanatory factors, and then evaluating the spatial variability of the relationships by combining the Principal Component Analysis (PCA), Multiscale Geographically Weighted Regression (MGWR) models and cartographic design techniques. MGWR evidenced spatially varying relationships operating at different scales. Lifestyles seem closely tied to the prevalence of asthma in most of the study area while urban functionality and local climate patterns seem to boost prevalence rates in some specific enclaves. Consequently, the social and environmental conditions that characterize the study area translate into several DH scenarios modulating the spatial distribution of asthma. This differential DH behavior detected by local regression models is relevant to guiding and refining public health decision-making.

Late Miocene continental birds from the Cerro Azul Formation in the Pampean region (central-southern Argentina)

Cenizo, M.M., Tambussi, C.P. & Montalvo, C.I., iFirst Article. Late Miocene continental birds from the Cerro Azul Formation in the Pampean region (central-southern Argentina). Alcheringa, 1–22. ISSN 0311-5518.

The oldest known birds from the Cerro Azul Formation are described, including the oldest records for the genera Eudromia and Nothura (Tinamidae), Milvago (Falconidae), Pterocnemia (Rheidae) and an undetermined Tyrannidae. The first remains of Phorusrhacidae for this formation are reported and a specimen previously referred to the giant teratorn Argentavis magnificens is reassigned to this family. We outline and update the current knowledge of the groups studied herein. The palaeornithological record from the Cerro Azul Formation is congruent with palaeoenvironmental inferences previously drawn from mammalian assemblages recovered from this unit, which point to the existence of open environments, possibly xerophyllous shrubby steppes, perhaps with some trees. These records are the first indications of a typically Pampean bird fauna at the end of the late Miocene in central-southern Argentina.     

Palaeontology of the Cerros Bayos section,Roca Formation (Danian), La Pampa Province,Argentina

Palynofloras from an outlier of Tertiary sediments in the One Tree Hill area north of Adelaide are nonmarine and correlate with similar assemblages from Middle Eocene North Maslin Sands from Maslin Bay and Golden Grove. Although there are similarities with time-equivalent Lower Nothofagidites asperus Zone palynofloras in the Gippsland Basin, a number of species in the South Australian palynofloras do not extend below the Late Eocene in the Gippsland sequences. This indicates earlier appearances for these species in southcentral Australia. The sediments overlie a highly weathered bedrock palaeosurface, indicating that a phase of significant weathering occurred prior to the Middle Eocene. A number of selected taxa are illustrated and their distribution in the palynofloras is discussed. Two new species, Proteacidites mildenhallii and Proteacidites parrawirrensis, are described and one species, Rhoipites byfieldensis, is emended.
