This paper focuses on the anthropic dynamics of environmental transformation and natural resource management in the specific case of the archaeological site of Tossal de la Vila in Castelló, Spain, a hillfort located at the end of the Eastern Iberian Cordillera. It presents two phases of occupation determined by multiple radiocarbon dating analyses: the first phase during the late Bronze Age (8th–7th centuries BCE) and the second at the beginning of the al-Andalus period (8th–10th centuries CE). The results of the comparison of the subsistence strategies and the biotic configuration of the natural environment in the same place at two different times have shown us that in the protohistoric period, the diversity of economic activities represented in the archaeobiological record is certainly heterogeneous, while in the al-Andalus period the complexity of these options is reduced to much less significant limits, possibly due to the different functionality of this space in both periods.

In this study we present evidence of braided plant fibres and basketry imprints on clay recovered from Coves de Santa Maira, a Palaeolithic-Mesolithic cave site located in the Mediterranean region of Spain. The anatomical features of these organic fibre remains were identified in the archaeological material and compared with modern Stipa tenacissima (esparto grass). Based on direct dating, the fragments of esparto cord from our site are the oldest worked plant fibres in Europe. Sixty fragments of fired clay are described. The clay impressions have allowed us to discuss the making of baskets and containers. According to their attributes and their functional interpretation, we have grouped them into five types within two broad categories, hearth plates and baskets or containers. The clay pieces identified as fragments of containers with basketry impressions are less common than those of hearth plate remains and they are concentrated in the Epipalaeolithic occupation material (13.2–10.2 ka cal bp). The clay impressions from Santa Maira indicate that some fibres were treated or flattened, a preparation process that is known from historical and ethnological sources. [ABSTRACT FROM AUTHOR]

This paper presents the results of the first excavation campaign of the Artusia rock shelter in Unzué, Navarre, Spain. Chronocultural and archaeobiological analyses revealed five different occupation phases (Artusia I–V) within the regional Mesolithic timeline, specifically in the Mesolithic of Notches and Denticulates (Artusia I and II) and the Geometric Mesolithic (Artusia III, IV, and V). In addition, the study of the sedimentological and palaeoenvironmental evolution in the entire record helped to clearly define several climatic events which developed around 6550 cal BC–8500 cal BP and 6250 cal BC–8200 cal BP. Here, we present a description of these events and their (pre)historical interpretation with the aim of recognizing how they influenced the Mesolithic hunter–gatherer groups living in the Ebro Basin of the Iberian Peninsula.

This study aimed to reconstruct the environmental conditions and the crop management practices and plant characteristics when agriculture appeared in western Europe. We analyzed oak charcoal and a large number of cereal caryopsides recovered from La Draga (Girona, Spain), an early (5300 to 4800 cal. BC) agricultural site from the Iberian Peninsula. The carbon isotope discrimination (Δ 13 C) values of oak, the dominant forest species in the region, indicates prevalence of a wet climate at the site. Further, we reconstructed crop management conditions, achievable yield, and crop characteristics through the analysis of Δ 13 C, nitrogen isotope composition (δ 15 N), nitrogen content, and the reconstructed weight of wheat and barley caryopsides, following protocols developed by our team [Araus et al. , Nat. Commun. 5 , 3953 (2014)] and comparison of these parameters with present-day organic agriculture in the region. In parallel, a regional perspective was achieved through the study of wheat and barley grains of seventeen Neolithic sites from the western Mediterranean. The results suggest that rather than small-garden cultivation, a more extensive agriculture was practiced under good water availability and moderate manuring. Moreover, results from La Draga evidence that grain weight and spike morphology were comparable to contemporary cereals. Growing conditions and the prevalence of improved crop traits indicate that agriculture was fairly consolidated at the time it reached the western edge of Europe., Competing Interests: Competing interests statement:The authors declare no competing interest.

There is a significant number of funerary contexts for the Early Neolithic in the Iberian Peninsula, and the body of information is much larger for the Late Neolithic. In contrast, the archaeological information available for the period in between (ca. 4800-4400/4200 cal BC) is scarce. This period, generally called Middle Neolithic, is the least well-known of the peninsular Neolithic sequence, and at present there is no specific synthesis on this topic at the peninsular scale. In 2017, an exceptional funerary context was discovered at Dehesilla Cave (Sierra de Cádiz, Southern Iberian Peninsula), providing radiocarbon dates which place it at the beginning of this little-known Middle Neolithic period, specifically between ca. 4800-4550 cal BC. Locus 2 is a deposition constituted by two adult human skulls and the skeleton of a very young sheep/goat, associated with stone structures and a hearth, and a number of pots, stone and bone tools and charred plant remains. The objectives of this paper are, firstly, to present the new archaeological context documented at Dehesilla Cave, supported by a wide range of data provided by interdisciplinary methods. The dataset is diverse in nature: stratigraphic, osteological, isotopic, zoological, artifactual, botanical and radiocarbon results are presented together. Secondly, to place this finding within the general context of the contemporaneous sites known in the Iberian Peninsula through a systematic review of the available evidence. This enables not only the formulation of explanations of the singular new context, but also to infer the possible ritual funerary behaviours and practices in the 5th millennium cal BC in the Iberian Peninsula., Competing Interests: The authors have declared that no competing interests exist.

Objective: To investigate the types of intestinal parasites that infected people living in Islamic period southern Iberia (al-Andalus), and compare with other regions of Europe., Materials: Four cesspits from 10 th -11 th century CE Córdoba (Spain), and two from 12 th -13 th century Mértola (Portugal)., Methods: Sediment from each cesspit was analyzed using digital light microscopy and enzyme-linked immunosorbent assay (ELISA)., Results: Analysis revealed eggs of roundworm (Ascaris lumbricoides) in every cesspit analyzed, but no evidence of other species of helminth or protozoal parasites., Conclusion: Differences were noted between parasite species found in Mediterranean Europe and northern Europe, where a range of zoonotic parasites were endemic alongside sanitation-related parasites. We suggest that the scarcity of zoonotic parasites in southern Europe in the medieval period may reflect contrasts in climate between northern and southern Europe., Significance: The repeated identification of roundworm eggs suggests that al-Andalus was less hygienic than historically depicted. We did not note a difference between parasites found in Muslim and Christian regions of Iberia, and the predominance of parasites spread by fecal contamination of food is consistent with past research., Limitations: The eggs of some species of parasite are fragile, so may theoretically have been present in the population but did not survive for us to identify them., Suggestions for Further Research: To further investigate the role of climate upon the parasites that affected past human populations., (Copyright © 2019 Elsevier Inc.
