Cordage, basketry and containers at the Pleistocene-Holocene boundary in southwest Europe. Evidence from Coves de Santa Maira (Valencian region, Spain)

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

Occurrence of whale barnacles in Nerja Cave (Málaga, southern Spain): Indirect evidence of whale consumption by humans in the Upper Magdalenian

A total of 167 plates of two whale barnacle species (Tubicinella majorLamarck, 1802 and Cetopirus complanatusMörch, 1853) have been found in the Upper Magdalenian layers of Nerja Cave, Mina Chamber (Maro, Málaga, southern Spain). This is the first occurrence of these species in a prehistoric site. Both species are specific to the southern right whale Eubalena australis, today endemic in the Southern Hemisphere. Because of Antarctic sea-ice expansion during the Last Glacial Period, these whales could have migrated to the Northern Hemisphere, and reached southern Spain. Whale barnacles indicate that maritime-oriented forager human groups found stranded whales on the coast and, because of the size and weight of the large bones, transported only certain pieces (skin, blubber and meat) to the caves where they were consumed

Car d’hom cert era: Pràctiques de canibalisme en el Mesolític de les Coves de Santa Maira (Castell de Castells, la Marina Alta, Alacant)

Es presenten evidències de pràctiques antropofàgiques en un grup del Mesolític mediterrani. S’han documentat trenta restes humanes en el nivell mesolític de les coves de Santa Maira. A més de la descripció de les marques antropogèniques identificades, també se situa la troballa en el seu context regional dins les pautes de subsistència dels grups mesolítics de la zona, i es plantegen hipòtesis sobre la seua intencionalitat

Taphonomic Criteria for Identifying Iberian Lynx Dens in Quaternary Deposits

For decades, taphonomists have dedicated their efforts to assessing the nature of the massive leporid accumulations recovered at archaeological sites in the northwestern Mediterranean region. Their interest lying in the fact that the European rabbit constituted a critical part of human subsistence during the late Pleistocene and early Holocene. However, rabbits are also a key prey in the food webs of Mediterranean ecosystems and the base of the diet for several specialist predators, including the Iberian lynx (Lynx pardinus). For this reason, the origin of rabbit accumulations in northwestern Mediterranean sites has proved a veritable conundrum. Here, we present the zooarchaeological and taphonomic study of more than 3000 faunal and 140 coprolite remains recovered in layer IIIa of Cova del Gegant (Catalonia, Spain). Our analysis indicates that this layer served primarily as a den for the Iberian lynx. The lynxes modified and accumulated rabbit remains and also died at the site creating an accumulation dominated by the two taxa. However, other agents and processes, including human, intervened in the final configuration of the assemblage. Our study contributes to characterizing the Iberian lynx fossil accumulation differentiating between the faunal assemblages accumulated by lynxes and hominins

Population genomics of post-glacial western Eurasia.

Western Eurasia witnessed several large-scale human migrations during the Holocene <sup>1-5</sup> . Here, to investigate the cross-continental effects of these migrations, we shotgun-sequenced 317 genomes-mainly from the Mesolithic and Neolithic periods-from across northern and western Eurasia. These were imputed alongside published data to obtain diploid genotypes from more than 1,600 ancient humans. Our analyses revealed a 'great divide' genomic boundary extending from the Black Sea to the Baltic. Mesolithic hunter-gatherers were highly genetically differentiated east and west of this zone, and the effect of the neolithization was equally disparate. Large-scale ancestry shifts occurred in the west as farming was introduced, including near-total replacement of hunter-gatherers in many areas, whereas no substantial ancestry shifts happened east of the zone during the same period. Similarly, relatedness decreased in the west from the Neolithic transition onwards, whereas, east of the Urals, relatedness remained high until around 4,000 BP, consistent with the persistence of localized groups of hunter-gatherers. The boundary dissolved when Yamnaya-related ancestry spread across western Eurasia around 5,000 BP, resulting in a second major turnover that reached most parts of Europe within a 1,000-year span. The genetic origin and fate of the Yamnaya have remained elusive, but we show that hunter-gatherers from the Middle Don region contributed ancestry to them. Yamnaya groups later admixed with individuals associated with the Globular Amphora culture before expanding into Europe. Similar turnovers occurred in western Siberia, where we report new genomic data from a 'Neolithic steppe' cline spanning the Siberian forest steppe to Lake Baikal. These prehistoric migrations had profound and lasting effects on the genetic diversity of Eurasian populations

The Solutrean Antlerworking in Hort de Cortés–Volcán del Faro (Valencia, Spain) in the Southwest Europe Context: a Preliminary Study

In this work, we present a preliminary analysis of the Solutrean antlerworking at Hort de Cortés–Volcán del Faro (Valencia, Spain) (ca. 26–21 ka cal BP). A restudy of its archaeological sequence, which came to encompass the Early Upper Palaeolithic to the Magdalenian period, has been a mandatory subject in the last years. This site became an archaeological reference since the beginning of its excavation in the 1960s but has not been systematically studied. The implementation of more specialized studies is used a) to observe the distribution of technical pieces in the stratigraphy and identify possible stratigraphic alterations and b) to restudy a huge lithic, osseous, and faunal collection which can provide new information that may clarify them. The aim is to develop a systematic study, from a technological point of view, to identify and characterize operational schemes and to define the modalities of antlerworking. The technological analysis of waste products, blanks, roughouts, and objects allows us to observe how raw material is obtained and transformed into a toolkit following the refitting by default method. It will help us analyze some questions about the raw material acquisition and transformation like (1) selection between hunted and shed antlers and its possible explanation, (2) the existence of planning of tool manufacture, and (3) the step-by-step production of the debitage. We will extract conclusions and analyze different social aspects: (1) by identifying technical traditions and comparing them with other studied sites and periods and (2) by knowing a new aspect of the way of life of these human groups
