Defining the Lead Isotopic Fingerprint of Copper Ores from North‐West Spain: The El Milagro Mine (Asturias)

This study is focused on the El Milagro mine (Asturias, Spain) and is part of a large‐scale effort on the measurement of the lead isotopic composition of Spanish copper ores from prehistoric mines in the provinces of Asturias and León, from which no data were available until recently. Lead isotopic values are compared to the published lead data from the El Aramo mine in the same region. The results show that both mines have a very similar lead isotopic composition, apart from some highly radiogenic samples in the El Milagro mine, which are clearly different from those previously reported for the Iberian Peninsula.     

An Industrial-Archaeological Approach to the Mineral Loading Docks in Rande Strait,North-Western Spain

During the 20th century, the need for raw material promoted a commercial transportation trade of iron ores from the deposits in north-western Spain, where Vigo city was considered one of the most important ports. The global energy crisis in the 1970s, as well as the strong competition from other exporting countries, dented the prolific activity of companies dedicated to the extraction and trading of iron ore. The main goal of this article is the evaluation of one particular element of the mining and industrial heritage — two old mineral loading docks in Ría de Vigo in the Rande Strait, linking the municipalities of Redondela and Moaña. Their development as a tourist resource would add to the cultural and economic activities already developed in the area.     

Oldest record of the scale-leaved clade of Podocarpaceae,early Paleocene of Patagonia,Argentina

A new podocarpaceous conifer is described from the early Danian Salamanca Formation (southern Chubut, Patagonia, Argentina) based on compressions of leafy branches with cuticular remains. Kirketapel salamanquensis gen. et sp. nov. has amphistomatic, scale-like leaves with marginal frills distinguishable at the apex; stomata oriented randomly in relation to the major axis of the leaf with four to five subsidiary cells and extremely reduced Florin rings; and irregularly shaped epidermal cells. We compare K. salamanquensis with extant and extinct members of the imbricate-leaved podocarps, among which it closely resembles Florin’s Dacrydium group C genera (i.e., Lagarostrobos, Manoao, Lepidothamnus and Halocarpus). Among these genera, only Lepidothamnus has a living representative in South America, the Chilean L. fonkii, whose leaf macro- and micromorphological characters are described in detail for comparison. Overall, the Patagonian fossil species is most similar to the extant and extinct members of Lagarostrobos in its cuticular micromorphology; however, macromorphological characters, such as the leaf size, apex curvature and mode of flattening, clearly differentiate it from all four genera of Dacrydium group C. We include Kirketapel salamanquensis in a combined molecular and morphological phylogenetic analysis conducted under the maximum parsimony criterion. The new, early Paleocene fossil taxon is confidently recovered as part of the scale-leaved clade as defined herein, which also includes Halocarpus, Phyllocladus, Lepidothamnus, Parasitaxus, Lagarostrobos and Manoao, and it constitutes the oldest record known for the group by at least 17 million years as well as its first fossil occurrence outside Australasia, establishing a widespread Gondwanan history. Furthermore, based on its oldest locality of occurrence, K. salamanquensis shows that the divergence of the total group of the scale-leaved podocarps occurred by at least 65 million years ago, adding to the growing systematic knowledge of earliest Cenozoic macrofloras in the Southern Hemisphere.

Settlement Dynamics and Social Organization in Eastern Iberia during the Iron Age (Eighth–Second Centuries BC)

Summary.   This paper explores the formation of urban societies in the eastern Iberian Peninsula. From the Early Iberian Iron Age onwards it is possible to trace the emergence of a hierarchical settlement pattern in which larger settlements carried out the most important functions of control and exploitation of the resources in this territory, extending their authority over several small farming villages. This settlement pattern is associated with the complex socio-economic structures and political organization of Iberian aristocracies. In this paper we will focus on the development of the Iberians' active role in exchanging goods with oriental traders; it is this contact which subsequently produces social change in the Iron Age period.     

Open Warfare or the Odd Skirmish? Bell Beaker Violence in the North‐Eastern Iberian Peninsula

Archaeological examples of violence in prehistory have increased in recent years. The evidence, methodology employed and interpretation of the data have been diverse, but in each case the myth of the ‘peaceful past’ is questioned. This work provides new data on the issue from the north‐eastern Iberian Peninsula, associated with the Bell Beaker culture (c.2800–2350 cal BC). Material from two megalithic tombs, Can Gol I and Can Gol II (Barcelona Province), in particular a set of flint arrowheads, has been revisited. Use‐wear analysis on the arrowheads confirmed the presence of impact fractures. This indicates that the arrowheads were not funerary offerings, but that they entered the graves lodged in the bodies of the deceased. The data from the only site with evidence of massive death by violence in the neighbouring region (Costa de Can Martorell) reinforce the hypothesis of episodes of conflict and violence during prehistory. However, the interpretation of the nature of such violence remains open to debate: was it an act of warfare or an occasional skirmish? And is the image of the Bell Beaker warrior identified in other European contexts also applicable to this area?
