Symbolic use of marine shells and mineral pigments by Iberian Neandertals

Two sites of the Neandertal-associated Middle Paleolithic of Iberia, dated to as early as approximately 50,000 years ago, yielded perforated and pigment-stained marine shells. At Cueva de los Aviones, three umbo-perforated valves of Acanthocardia and Glycymeris were found alongside lumps of yellow and red colorants, and residues preserved inside a Spondylus shell consist of a red lepidocrocite base mixed with ground, dark red-to-black fragments of hematite and pyrite. A perforated Pecten shell, painted on its external, white side with an orange mix of goethite and hematite, was abandoned after breakage at Cueva Antón, 60 km inland. Comparable early modern human-associated material from Africa and the Near East is widely accepted as evidence for body ornamentation, implying behavioral modernity. The Iberian finds show that European Neandertals were no different from coeval Africans in this regard, countering genetic/cognitive explanations for the emergence of symbolism and strengthening demographic/social ones.

The Upper Paleolithic in Mediterranean Spain: A Review of Current Evidence

In spite of an active and sophisticated archaeological research program, the Paleolithic of the Iberian peninsula remains comparatively little known to English-speaking prehistorians, with the exception of Cantabrian Spain. The rich data set compiled by Spanish prehistorians and their colleagues over the past several decades stands to make a valuable and unique contribution to our understanding of the Pleistocene prehistory of Europe. We present a detailed overview of Upper Paleolithic chronology, sites, and assemblages for Mediterranean Spain, an area of over 1,600,000 km2that extends from the French border to the Straits of Gibraltar. To interpret these data, we employ a regional perspective that emphasizes studies of paleoeconomy (especially zooarchaeology) and settlement. The Middle–Upper Paleolithic transition and Upper Paleolithic art also receive detailed treatment, and the Upper Paleolithic of Mediterranean Spain is discussed in the broader context of the late Upper Pleistocene of western Europe and the Mediterranean Basin.

The Pleistocene/Holocene transition in the Iberian Peninsula: Continuity and change in human adaptations

Abstract Data obtained from recent excavations (as well as from selected older excavations) are used to outline the principal environmental, technological and economic aspects of the Pleistocene–Holocene transition in three distinct regions of the Iberian Peninsula: Portugal, Cantabrian and Mediterranean Spain. The period covered extends from the terminal Paleolithic Magdalenian period to the initial Neolithic. Despite proximity to SW France and many similarities with that classic prehistoric culture area in terms of artistic/symbolic expression and technology, the Iberian regions show significant differences, especially in terms of subsistence strategies and their development during the Tardiglacial. While there are striking similarities among the three regions with respect to overall patterns of changes in technology, art and subsistence, there are interesting differences of detail, probably linked to environmental differences among these distinctive coastal zones. Changes in artistic activity are also examined, including the disappearance of cave art and the development of geometric motifs in mobile art in Cantabria, as well as a reinterpretation of Levantine art.

The human remains from Cova Negra (Valencia, Spain) and their place in European Pleistocene human evolution

Abstract The phylogenetic and chronological positions of the Cova Negra human remains are discussed. These remains include an adult right parietal bone, a juvenile right mandibular body fragment with a deciduous second molar, and an isolated permanent upper central incisor. There are 40 levels in the Cova Negra sedimentary sequence, ranging from the Riss-Wurm to the beginning of the Wurm III. The Cova Negra A phase (Riss-Wurm) is faunally and industrially sterile. Several variants of the Mousterian (Charentian type) are known from the beginning of the Wurm (Cova Negra B phase) to the end of the sequence (Cova Negra E and F phases). All human remains are assigned to the Wurm. On the basis of the parietal bone, uni- and bivariate analyses show that the Cova Negra biparietal vault was very broad. The cluster analysis groups Cova Negra with the biggest Neandertal neurocrania (specimens generally sexed as males). Also, this parietal bone exhibits a subcircular profile in posterior view, a trait considered as a Neandertal autapomorphy. The mandibular fragment shows three foramina mentalia and a steep linea mylohyoidea. These and other traits lead us to include this specimen in the Neandertal group. The crown dimensions and the morphology of the deciduous molar are consistent with this taxonomic attribution. The comparative study of the crown and root dimensions of the permanent incisor, as well as the presence of traits such as a strong tuberculum linguale, well developed marginal ridges (shovelling), and the marked lingual inclination of the buccal face, lead us to attribute this tooth to the Neandertal group.

Large carnivore attacks on hominins during the Pleistocene: a forensic approach with a Neanderthal example

Interaction between hominins and carnivores has been common and constant through human evolution and generated mutual pressures similar to those present in worldwide modern human-carnivore conflicts. This current interaction is sometimes violent and can be reflected in permanent skeletal pathologies and other bone modifications. In the present paper, we carry out a survey of 124 forensic cases of dangerous human-carnivore encounters. The objective is to infer direct hominin-carnivore confrontation during the Pleistocene, which is important to understand behavioral changes during human evolution. In addition, the case of Neanderthals is analyzed in order to find evidence of past attacks using forensic observations. The results obtained pose that Neanderthals could potentially have been involved in dangerous encounters during the Pleistocene, validating our methodology to approach past attacks from a forensic perspective.

Symbolic use of marine shells and mineral pigments by Iberian Neandertals 115,000 years ago

U-Th dating of archaeological deposits of Cueva de los Aviones provides evidence for Neandertal symbolism 115,000 years ago. Cueva de los Aviones (southeast Spain) is a site of the Neandertal-associated Middle Paleolithic of Europe. It has yielded ochred and perforated marine shells, red and yellow colorants, and shell containers that feature residues of complex pigmentatious mixtures. Similar finds from the Middle Stone Age of South Africa have been widely accepted as archaeological proxies for symbolic behavior. U-series dating of the flowstone capping the Cueva de los Aviones deposit shows that the symbolic finds made therein are 115,000 to 120,000 years old and predate the earliest known comparable evidence associated with modern humans by 20,000 to 40,000 years. Given our findings, it is possible that the roots of symbolic material culture may be found among the common ancestor of Neandertals and modern humans, more than half-a-million years ago.

Precise dating of the Middle-to-Upper Paleolithic transition in Murcia (Spain) supports late Neandertal persistence in Iberia

The late persistence in Southern Iberia of a Neandertal-associated Middle Paleolithic is supported by the archeological stratigraphy and the radiocarbon and luminescence dating of three newly excavated localities in the Mula basin of Murcia (Spain). At Cueva Antón, Mousterian layer I-k can be no more than 37,100 years-old. At La Boja, the basal Aurignacian can be no less than 36,500 years-old. The regional Middle-to-Upper Paleolithic transition process is thereby bounded to the first half of the 37th millennium Before Present, in agreement with evidence from Andalusia, Gibraltar and Portugal. This chronology represents a lag of minimally 3000 years with the rest of Europe, where that transition and the associated process of Neandertal/modern human admixture took place between 40,000 and 42,000 years ago. The lag implies the presence of an effective barrier to migration and diffusion across the Ebro river depression, which, based on available paleoenvironmental indicators, would at that time have represented a major biogeographical divide. In addition, (a) the Phlegraean Fields caldera explosion, which occurred 39,850 years ago, would have stalled the Neandertal/modern human admixture front because of the population sink it generated in Central and Eastern Europe, and (b) the long period of ameliorated climate that came soon after (Greenland Interstadial 8, during which forests underwent a marked expansion in Iberian regions south of 40°N) would have enhanced the “Ebro Frontier” effect. These findings have two broader paleoanthropological implications: firstly, that, below the Ebro, the archeological record made prior to 37,000 years ago must be attributed, in all its aspects and components, to the Neandertals (or their ancestors); secondly, that modern human emergence is best seen as an uneven, punctuated process during which long-lasting barriers to gene flow and cultural diffusion could have existed across rather short distances, with attendant consequences for ancient genetics and models of human population history.

Neanderthal use of plants and past vegetation reconstruction at the Middle Paleolithic site of Abrigo de la Quebrada (Chelva, Valencia, Spain)

Despite phytoliths having been used to understand past human use of plants and palaeoenvironment in Middle Paleolithic sites, little is known on this aspect in the well-documented central region of Mediterranean Iberia. This paper presents the first phytolith and mineralogical study conducted at Abrigo de la Quebrada (Chelva, Valencia). Forty-one samples were analyzed through phytoliths and Fourier transform infrared spectroscopy (FTIR) from different areas, stratigraphic levels, and archeological contexts (hearth, hearth-related, and non-hearth-related sediments) of the shelter. The results obtained point towards a different pattern of preservation in the site depending firstly on the stratigraphy and secondly on the area where the samples were collected. Postdepositional processes that may have chemically affected phytolith preservation are discussed. Grasses are the main plant component identified in all the samples while woody plants are scarce. The abundance of grasses in the non-hearth-related sediments might be related, at least partially, to the dispersion of ashes from hearths, as indicated by the FTIR results. The results are indicative of an occupation of the site during the spring-autumn season. At this time, the area would be dominated by a semi-open environment with supramediterranean vegetation.

Identification of plant cells in black pigments of prehistoric Spanish Levantine rock art by means of a multi-analytical approach. A new method for social identity materialization using chaîne opératoire

We present a new multi-analytical approach to the characterization of black pigments in Spanish Levantine rock art. This new protocol seeks to identify the raw materials that were used, as well as reconstruct the different technical gestures and decision-making processes involved in the obtaining of these black pigments. For the first of these goals, the pictorial matter of the black figurative motifs documented at the Les Dogues rock art shelter (Ares del Maestre, Castellón, Spain) was characterized through the combination of physicochemical and archeobotanical analyses. During the first stage of our research protocol, in situ and non-destructive analyses were carried out by means of portable Energy Dispersive X-Ray Fluorescence spectrometry (EDXRF); during the second stage, samples were analyzed by Optical Microscopy (OM), Raman spectroscopy, and Scanning Electron Microscopy coupled with Energy Dispersive X-ray spectroscopy (SEM-EDX). Two major conclusions have been drawn from these analyses: first, charred plant matter has been identified as a main component of these prehistoric black pigments; and second, angiosperm and conifer charcoal was a primary raw material for pigment production, identified by means of the archaeobotanical study of plant cells. For the second goal, black charcoal pigments were replicated in the laboratory by using different raw materials and binders and by reproducing two main chaînes opératoires. The comparative study of the structure and preservation of plant tissues of both prehistoric and experimental pigments by means of SEM-EDX underlines both a complex preparation process and the use of likely pigment recipes, mixing raw material with fatty or oily binders. Finally, the formal and stylistic analysis of the motifs portrayed at Les Dogues allowed us to explore the relationship between identified stylistic phases and black charcoal pigment use, raising new archaeological questions concerning the acquisition of know-how and the transfer of traditionally learned chaînes opératoires in Spanish Levantine rock art.

Luminescence Dating of Fluvial Deposits in the Rock Shelter of Cueva Antón, Spain

Abstract The fluvial sediments at Cueva Antón, a Middle Palaeolithic rock shelter located in the valley of the River Mula (Southeast Spain), produced abundant lithic assemblages of Mousterian affinities. Radiocarbon dates are available for the upper part of the archaeological succession, while for the middle to lower parts chronometric data have been missing. Here we present luminescence dating results for these parts of the succession. Quartz OSL on small aliquots and single grain measurements yield ages ranging from 69 ± 7 ka to 82 ± 8 ka with a weighted mean of 72 ± 4 ka for sub-complexes AS2 to AS5. Equivalent dose estimates from large aliquots were highest and inconsistent with those from single grains and small multiple grain aliquots. This is probably caused by the presence of over-saturating grains, which have been quantified by single grain measurements. Additional post-IR IRSL measurements on coarse grained feldspar give strong support to a well-bleached quartz OSL signal. While independent chronometric control is missing, the results are within the expected age range and support the notion of a rapid accumulation of the fluvial deposits.
