Here we analyze the radiocarbon record of Iberia to reconstruct long-term changes in population levels and test different models of demographic growth during the Last Glacial-Interglacial transition. Our best fitting demographic model is composed of three phases. First, we document a regime of exponential population increase during the Late Glacial warming period (c.16.6-12.9 kya). Second, we identify a phase of sustained population contraction and stagnation, beginning with the cold episode of the Younger Dryas and continuing through the first half of the Early Holocene (12.9-10.2 kya). Finally, we report a third phase of density-dependent logistic growth (10.2-8 kya), with rapid population increase followed by stabilization. Our results support a population bottleneck hypothesis during the Last Glacial-Interglacial transition, providing a demographic context to interpret major shifts of prehistoric genetic groups in southwest Europe.

Various hypotheses have been used to explain the disappearance of Neanderthals from Eurasia. However, very few studies have explicitly examined the causative role of demography on Neanderthal and anatomically modern humans (AMH) interaction. Here we use an integrative method based on computational modelling and the analysis of archaeological data to construct an agent based model that explores the influence of demographic variables (birth and death rates) and mobility (home range size) on the bio-cultural interaction between AMH and Neanderthals during the transition from the Middle to Upper Palaeolithic on the Iberian Peninsula (50 ka to 30 ka BP). Our simulation results are consistent with the current radiocarbon framework for the disappearance of Neanderthals in this region. This suggest that the extinction of Neanderthals could be explained by inter-specific differences in demographic behaviour and mobility patterns compared with AMH.

Previous studies have produced 14 radiocarbon dates using bone collagen samples from human burials. However, no attempt has been made to date the stratigraphic sequence to address the formation time of the shell midden and establish a chrono-stratigraphic framework for the study of bio-archaeological and cultural assemblages. We critically evaluate the available radiocarbon record of the site and present 6 new AMS radiocarbon dates on ungulate bones with anthropic fractures and bivalves from the three major stratigraphic horizons. Then, we integrate our results with previously published AMS radiocarbon determinations on human samples into a chronological Bayesian model, constraining the radiocarbon distributions with prior information about the samples stratigraphic provenance. Finally, we correlate the results of the chronological model with the regional archaeological sequence and the available data on coastal evolution at regional and local scales. The vertical distribution of the radiocarbon dates makes evident some strati-graphic disturbance caused by the repeated presence of pit graves, agricultural activities and low stratigraphic control of the excavation process. However, once the problematic determinations are identified as outliers, the remaining radiocarbon dates grouped according the major stratigraphic divisions , and the calibrated distributions modelled-constrained, the resulting Bayesian phase model reveal high agreement index (Ac ¼ 103). The shell midden formation took place from the bottom of the sequence, spanning 1022e1965 calibrated years (CI 95.4%). The occupations documented at Phase 1 (Level IV) are dated to the Early Holocene (9828e9551 cal BP). The Phase 2 (Level II), encompass radiocarbon evidence of both burial and occupational activities dated to 9437 to 8477 cal BP, spanning 779e985 calibrated years (CI 95.4%). Finally, the Phase 3 (Level I) records Late Mesolithic occupations deposited between 8509 and 8391 cal BP for the start boundary and 8499e8060 cal BP for the end boundary (CI:95.4%). There are no individual radiocarbon dates during or postdating the chronological span of the 8.2 ka climatic event (8300e8140 cal BP).

Human palaeodietary reconstructions based on bone collagen d 13 C and d 15 N isotope ratios, identified a variable contribution of marine proteins, ranging from fully terrestrial diets to a maximum input of 25%. Most subsequent research on Mediterranean coastal and dietary adaptations refers to the site's funerary record and palaeodietary study, but the composition of its shell midden has remained unstudied. This work reports the first systematic study of a representative sample of mollusc and a comparatively small assemblage of fish bone recovered from the different stratigraphic horizons of El Collado site. Results indicate a mixed marineeterrestrial mollusc composition of the shell midden. The edible land snail Sphincterochila candidissima and the marine bivalve Cerastoderma glaucum are the best represented species throughout the archaeological sequence. The pattern of intertidal resource exploitation is clearly dominated by bivalves (C. glaucum, Glycimeris violacescens, and Ruditapes decussatus) and gastropods (Cerithium vulgatum, Hexaplex trunculus) inhabiting mud and sand flats in coastal lagoon environments. The presence of rocky shore intertidal species is minimal, mostly related to the manufacture of pierced shell ornaments made from Columbella rustica. On the other hand, fish bone assemblages are overwhelmingly dominated by the gilthead sea bream (Sparus aurata) a coastal species frequent in brackish water coastal lagoons and estuaries, both on rocky and sandy grounds. The biometric analysis of C. glaucum records differences on shell size amongst the different layers, suggesting variations of marine productivity throughout the archaeological sequence.

In this paper, we analyze people’s perceptions of environmental and climate-related transformations in com-munities across the Western Solomon Islands throughethnographic and geospatial methods. Specifically, we docu-mented people’s observed changes over the past decadesacross various environmental domains, and for each change,we asked respondents to identify the causes, timing, andpeople’s adaptive responses. We also incorporated thisinformation into a geographical information system databaseto produce broad-scale base maps of local perceptions of environmental change. Results suggest that people detectedchanges that tended to be acute (e.g., water clarity, loggingintensity, and agricultural diseases).

These dry events consist of an increase in the aridity quotient calculated as a function of selected pollen taxa at 13.4, 13, 12.55, 12.2, 11.9, 11.45, 11, 10.6, 10.3, 10, 9.5 and 8.3 ka cal BP. These dry events correspond to the previous identified cold spells such as the Younger Dryas, as well as the 8, 7, 6 and 5 Bond events, and 11.4 and 9.3 events. This climate record highlights the complex glacial-interglacial transition in extra-tropical latitudes, with centennial-scale abrupt climate fluctuations, a signature scarcely recorded in other palaeoecological records of the SE Iberian Peninsula. This work has major implications for the study of human socio-ecological systems and resilience in SE Iberia during the Epipaleolithic and Mesolithic periods.

However, the difficulty in developing suitable chronological frameworks from surface assemblages has limited their use. Additionally, surface scatters are composed of artifacts that can accumulate across multiple occupational episodes. A challenge to chronology building in such surface contexts is the necessity to assess the probability of occupation during each time period. We describe a new method of dating surface lithic assemblages using empirical Bayesian methods, with an example from northeastern Spain. We use Bayesian methods to estimate the probability of occupation during 11 temporal periods (c.13,000-4,200 cal BP) for a sample of 25 lithic surface. A Bayesian approach allows us to combine prior knowledge, with different degrees of uncertainty, about the temporal sensitivity of projectile forms statistically derived from a regional calibration data set of 35 dated assemblages to estimate the age of each surface collections probabilistically. This approach provides new insight into the settlement history of the Maestrat in the first half of the Holocene, during the transition from foraging to food production and offers a powerful tool to archaeologists for the dating of surface collections.

excavation was conducted over two seasons in 1987 and 1988. The archaeological work
excavated a surface area of 143m2 where 14 burials were discovered, providing skeletal remains
from 15 individuals. We have obtained AMS dates for 10 of the 15 individuals by
means of the direct dating of human bones. The ranges of the probability distribution of the
calibrated dates suggest that the cemetery was used during a long period of time (781–
1020 years at a probability of 95.4%). The new dates consequently set back the chronocultural
attribution of the cemetery from the initial proposal of Late Mesolithic to an older
date in the Early Mesolithic. Therefore, El Collado becomes the oldest known cemetery in
the Iberian Peninsula, earlier than the numerous Mesolithic funerary contexts documented
on the Atlantic façade such as the Portuguese shell-middens in the Muge and Sado Estuaries
or the funerary sites on the northern Iberian coast.

In this paper, we report the oldest evidence of land snail exploitation as a food resource in Europe dated to 31.3-26.9 ka yr cal BP from the recently discovered site of Cova de la Barriada (eastern Iberian Peninsula). Mono-specific accumulations of large Iberus alonensis land snails (Ferussac 1821) were found in three different archaeological levels in association with combustion structures, along with lithic and faunal assemblages. Using a new analytical protocol based on taphonomic, microX-Ray Diffractometer (DXR) and biometric analyses, we investigated the patterns of selection, consumption and accumulation of land snails at the site. The results display a strong mono-specific gathering of adult individuals, most of them older than 55 weeks, which were roasted in ambers of pine and juniper under 375°C. This case study uncovers new patterns of invertebrate exploitation during the Gravettian in southwestern Europe without known precedents in the Middle Palaeolithic nor the Aurignacian. In the Mediterranean context, such an early occurrence contrasts with the neighbouring areas of Morocco, France, Italy and the Balkans, where the systematic nutritional use of land snails appears approximately 10,000 years later during the Iberomaurisian and the Late Epigravettian. The appearance of this new subsistence activity in the eastern and southern regions of Spain was coeval to other demographically driven transformations in the archaeological record, suggesting different chronological patterns of resource intensification and diet broadening along the Upper Palaeolithic in the Mediterranean basin.

Live-collected individuals exhibited body ( 21.8 1.6%) and shell ( 5.8 1.4%) d13C values typical of a C3 plant diet, probably combined with carbonate ingestion. Calculations of a carbon flux balance-mixing model suggest that living specimens experienced similar metabolic rates, with comparable ratio of input and output fluxes of bicarbonate from the snail hemolymph. All fossil shells showed comparable d13C values among each other, but values were 2% higher than living specimens. This may be explained by higher water stress at the YD–Holocene transition or by the Suess effect. Shell d18O values averaged þ1.3 0.8% for living individuals, 0.5 0.8% for Holocene (8.4–10.2 cal ka BP) specimens and þ0.4 0.6% for YD (12.0–12.4 cal ka BP) snails. An oxygen flux balance-mixing model suggests that YD shells precipitated during relative humidity (RH) values of 79–82%, after which RH increased gradually reaching maximum values of 87–88% at 8.4–8.6 cal ka BP and, from there, RH eventually declined to present values of 82%. Comparisons with other snail data suggest that the xerophilous

We provide direct AMS radiocarbon dating and carbon (δ13C) and nitrogen (δ15N) stable isotope analysis were carried out on bone collagen samples of two single burials from the recently discovered open-air Late Mesolithic site of Casa Corona (Villena, Spain). The results shed new light on the chronology and subsistence patterns of the last Mesolithic communities in the Central Mediterranean region of the Iberian Peninsula. Radiocarbon results date the human remains and funerary activity of the site to 6059-5849 cal BC, statistically different from other Late Mesolithic sites and the earliest Neolithic contexts, and bridging the 500 yrs chronological gap of the Mesolithic-Neolithic transition from the area. Isotopic evidence shows that diet was based on terrestrial resources despite the proximity to the site of lagoon and marine ecosystems. This and previous isotope studies from the region suggest a lower reliance upon marine resources than for Atlantic and Cantabrian sites, although intra-regional patterns of neighbouring Mesolithic populations exhibit both fully terrestrial diets and diets with significant amounts of aquatic resources in them. We hypothesize that in the Central Mediterranean region of Spain the Late Mesolithic dietary adaptations imposed structural limits on demographic growth of the last foragers and favoured rapid assimilation by the earliest Neolithic populations.

Recent excavations have provided evidence of non-marine assemblages dominated by terrestrial (Sphincterochila candidissima and Iberus alonensis) and fresh water gastropods (Melanopsis tricarinata tricarinata) associated with habitation structures. These sites represent the first documented cases of systematic land snail consumption at
open-air residential camps in the Iberian Mediterranean Region. This report presents the assemblage composition and modern ethological parameters, and discusses taphonomic processes, gathering strategies, seasonal patterns and their implications in subsistence practices. The pattern of occurrence of these species is contrasted with lake environmental records at a local scale to trace paleoecological conditions in the study area.

ABSTRACT: Fieldwork carried out in the prehistoric site of Arenal de la Virgen (Villena, Alicante) have provided thorough evidences for the first lacustrine occupation belonging to Notches and Denticulates Mesolithic in the Iberian Peninsula. In this paper we present chronostratigraphical and palaeoenvironmental data along with material culture, subsistence and habitat record. The whole information is discussed in the context of cultural processes and environmental dynamics that took place along Early and Middle Holocene transition in the Iberian Mediterranean region. The results point out an advanced chronology in the Notches and Denticulates Mesolithic period and situate the occupation in one of the most humid periods during the
Holocene.

Particularly important in this region, the 8,200 cal BP event is marked by colder and more arid conditions. During this episode, we identify a pattern of abandonment episodes at five Late Mesolithic sites. We suggest that such desertion episodes are correlated with adjustments in the logistic mobility system undertaken in the context of broader structural changes in regional settlement organization.

Abstract : Tabular flint use in the late prehistory of Valencian country (Mediterranean Spain). The on tabular flint lithic production is one of the more significant technological characteristics of the Late Neolithic and Eneolithic periods in the Valencian country. The exploitation and the use of this type of flint is reduced to these periods, and it's usually associated with craft productions (large knives and daggers) and raw material circulation networks. The site of Ereta del Pedregal (Navarrés, Valencia), an important establishment of habitat, has delivered the best ensemble of tabular flint with two differents techno-industrial destinations according two varietys : the local tabular flint was employed to manufacture arrowheads, while the no local tabular flint were used preferentially to fabricate cutting tools. This second production in the site of Ereta, according to the stratigraphic available data, appears to be placed at he initial time of the neo-eneolithic sequence.
discoveries and discussion points about Late Mesolithic and
Early Neolithic art in Eastern Spain. First, we will review the post-
Palaeolithic sequence to give an account of recent advances
in chronology and interpretative changes in cultural affiliation
of some styles. Then, we will focus on the main spatio-temporal
patterns of stylistic variation at the macro-regional scale. Such
a perspective is more suitable for analysing the relationship
between social contexts of art production with the underlying
mechanisms of the neolithisation process (spread of farming,
cultural interaction between foragers and farmers, ethnicity and
social networks among different Neolithic groups).
We will argue that the Neolithic transition in the study area
involved an abrupt change in artistic traditions and belief systems.
For this presentation, we provide an updated overview of the
post-Palaeolithic artistic sequence as an empirical framework for
further discussions about the neolithization process in Eastern
Spain.
The Iberian Mediterranean region harbours one of the
richest post-Palaeolithic rock art records of Southern Europe. The
current data is irregularly distributed over the archaeological
sequence. During the Late Mesolithic (of Castelnovian tradition),
the art record is fragmentary, quantitatively meaningless and
geographically sparse. Technically, it consists of linear and
geometric (non figurative) motifs engraved on small slabs.
To date, no parietal evidence has been definitely attributed
to this chronological horizon. On the basis of technical and
graphic conceptions, no phylogenetic relationships can be
established regarding the engraved Upper Magdalenian or Early
Epipaleolithic parietal and mobile art.
In contrast, the record of figurative and geometric
representations on both rock and portable art dated to the Early
Neolithic is overwhelmingly higher and varied. It encompasses
different rock art styles with figurative and geometric motifs,
also represented in ceramic wares found in archaeological
contexts. Three main styles are dated at the Neolithic period: the Macroschematic, the Schematic and the Levantine rock art.
The Macroschematic art is geographically restricted to the
central region of Mediterranean Spain. Its distribution is delimited by the settlement territory of the earliest Cardial Neolithic sites. It mainly consists of large representations of individual or double anthropomorphic figures with upraised arms, series of parallel curved lines and zigzags and other schematic motifs interpreted as human, vegetation or bull representations. This imagery reflects a strong symbolic and religious component, closely connected with iconographic concepts identified in the material culture of
other Mediterranean Neolithic cultures.
The Schematic rock art displays a wider geographical
distribution and more extended chronology, from the Early
Neolithic through the Bronze Age. Schematic motifs include
very simplistic representations of anthropomorphic and
zoomorphic figures (sheep, deer) and other geometric ones
such as bars, broken lines, triangles, suns or dots created with
digital imprints. Recent studies on rock art and material culture
have allowed the identification of an iconographic body of
Early Neolithic representations, which displays formal and
conceptual similarities with the Macroschematic art. In fact,
motifs of both styles are well documented on Early Neolithic
ceramic decorations during the Cardial and Epicardial phases.
A noticeable variability in rock art sites in terms of motifs, location
patterns, number of representations and composition complexity
suggest different social contexts of production and use.
Finally, the Levantine style is characterized by figurative and
naturalistic representations of animals and human figures often in
scenes with a clear narrative sense (animalistic scenes, individual
and collective hunting events, social aggregations and warfare
confrontations). It is widely distributed along the Mediterranean
regions of the Iberian Peninsula except for Central and Northern
Catalonia.
Stylistic variability within the Levantine rock art gives
account of both regional variations and chronological differences also reflected in technical and composition conceptions. From a regional perspective, it suggests the emergence of intergroup identity processes that operated at different geographic scales.
The chronology and cultural affiliation of the Levantine rock
art has been deeply discussed during last decades. Chromatic
stratigraphy, by means of superimposition of Levantine figures to Macroschematic and Early Schematic motifs, clearly indicates
a Neolithic chronology. Previously accepted, Levantine
mobiliar evidences on impressed ceramics have been recently
discarded and attributed to the Schematic style. In addition, the
representation of some objects associated with Levantine human figures, such as bracelets, some specific types of geometric microliths (crescents or long trapezes) and bifacial arrow points argues for a Neolithic chronology as well, encompassing more advanced archaeological phases (Middle Neolithic, Late Neolithic and Eneolithic). Recently, the relative chronology based on radiocarbon dating on oxalate crusts brackets the production of Levantine figures between the 6th and the 2nd millennium cal. BC.
Neolithic transition. In conclusion, we propose that the initial colonization process was the result of two successive and spatially heterogeneous migrations: Maritime Pioneer Colonization and targeted migration to places favorable to the new economic system.

Sin embargo, la incorporación de estas herramientas no ha ido siempre acompañada de la introducción de protocolos normalizados de adquisición, producción y publicación de datos espaciales. Este problema ha derivado
en situaciones prácticas de fragmentación de la información geoespacial y de imprecisión locacional. En este contexto urge el desarrollo de acciones coordinadas entre las distintas administraciones e instituciones implicadas
en la gestión e investigación del Arte Rupestre. La presente comunicación plantea posibles líneas de trabajo en este sentido empleando como marco de referencia el paradigma de las Infraestructuras de Datos Espaciales.

Abstract: Since the declaration of the Rock Art at the mediterranean façade in the World Heritage list, we have witnessed a global technological revolution. The use of Global Position Systems and the growing use of Geographical Information Systems are the main poles of this renewal process.However the use of these technologies has not been followed always by the introduction of normalized protocols on the production and publication of spatial data. This problem is responsible of practical situations of fragmented spatial information and locational inaccuracies. In this context, it is necessary coordinate actions by the different administrations and institutions involved on the rock art research and management. This text explores different proposals using as reference the Spatial Data
Infrastructures paradigm.

Se presenta un avance de los resultados obtenidos en la excavación de un nuevo yacimiento neolítico ubicado
en el núcleo de arte rupestre levantino Valltorta-Gasulla. Su secuencia presenta diversos niveles arqueológicos
comprendidos entre el Mesolítico Reciente y el Neolítico Final. Se incide en la aproximación a las características
de las ocupaciones desde los estudios tafonómicos, y en su integración en el proceso de neolitización a escala
regional.
Abstract
We present an advance of the excavation results of a new Neolithic site located in Valltorta-Gasulla Rock Art
nucleus. Their sequence presents diverse archaeological levels between the Recent Mesolithic and Final Neolithic
periods. We make a first approach to the characteristics of the occupations from the taphonomy, and the site is
integrated in the neolithisation process to regional scale.
industrias líticas talladas que durante los últimos años hemos realizado diferentes contextos de hábitat neolíticos del área
septentrional del País Valenciano.La producción lítica de este periodo incorpora dos novedades significativas:
1.-La documentación del tratamiento térmico en la producción laminar y en la fabricación de puntas de flecha, sobre los que
se presentan diversos testimonios.
2.-El empleo de la técnica de microburil en la fracturación de los soportes laminares como un procedimiento técnico
estrechamente ligado a la fabricación de armaduras geométricas del Neolitico Final y el Eneolítico.
Estos aspectos son valorados en el marco de la evolución de las industrias líticas del Neolítico en la fachada mediterránea
de la Peninsula Ibérica.

ABSTRACT: The arrow-heads in the Levantin Rock Art: apports from the projectil analysis from the archaeological record of the Riu de les Coves (Alt Maestrat, Castelló). In this paper we study the arrow-heads of Levantin Rock in contrast camparation with the lithic projectiles founded in the Mesolithic and Neolithic sites of Valltorta-Gasulla prehistoric art core. The analysis of the differents ways of representation and the patterns of use, inferred after the use-wear study of archaeological projectiles, shows the importance of the armament associated to the late Neolithic phases. The differences in the Mediterranean context about the projectil techonology and their representation in the rock art, suggest the existence of regionalisation process.

Partiendo de los problemas derivados de la naturaleza de la información manejada se aborda su contextualización en el marco de la
secuencia arqueológica y del hábitat del Holoceno inicial en el Maestrazgo y en el contexto regional. Los resultados obtenidos permiten
por un lado, relativizar la idea de una secuencia local continua e ininterrumpida desde el Magdaleniense superior hasta el Mesolítico
Reciente, y por otro, la sucesión de dos modelos diferentes de ocupación del territorio.

In this paper we present the study of five different sites located in the Riu de les Coves (Alt Maestrat, Castellón). Bearing in mind the problems
related with the nature of the managed data, they will be contextualized in the Early Holocene archaeological sequence of the
Maestrazgo area and also on a broader regional context. The results allow us, on the one hand, to reconsider the general idea about a
continuous and interrupted local sequence from the Upper Magdalenian to the Late Mesolithic, and in the other hand, to establish two
different settlements models successive on time.
Key words: Epipaleolithic, Mesolithic, archaeological sequence, settlement
work we’ll present the results of the morphological, technological and use-wear studies from different sites –villages and burials– of the Mediterranean
side (Cataluña and País Valenciano).
During the Early and the Middle Neolithic the geometric microliths used like projectiles have a good representation. However during the Late
Neolithic and the Chalcolithic periods the importance of the projectiles elements is major in the bifacial arrow heads than the microliths."
établissement d’habitat, est celui qui a livré les meilleures données sur l’approvisionnement en silex en plaquettes, tant sur le plan des variétés exploitées (les unes locales, d’autres sans doute de provenance étrangère), que sur celui des procédés de transformation. En ce qui concerne ces derniers aspects, on a ainsi pu observer des destinations techno-industrielles différentes selon les classes de plaquettes : celles
d’origine locale ont été employées pour la fabrication de pointes de flèches, tandis que celles qui semblent avoir une autre origine, ont été utilisées préférentiellement pour la mise en forme d’outils coupants. Cette seconde production paraît se placer au moment initial de la séquence néo-énéolithique si l’on se fie aux indications stratigraphiques disponibles dans le site de la Ereta.
la culture matérielle, comme un des éléments les plus caractéristiques de l’Énéolithique de la région valencienne, en raison de leur présence généralisée - surtout - dans les mobiliers funéraires des nombreuses grottes sépulcrales de cette période. Hormis la simple constatation de la taille exceptionnelle de quelques exemplaires par rapport aux produits laminaires des étapes plus anciennes du Néolithique, aucune étude approfondie n’a été consacrée à ces lames. L’objectif de cet article est d’entreprendre une telle approche dans une perspective globale et analytique. Nous rendrons ici compte des matières premières employées et de leur problématique, des modules typométriques documentés et de leur signification, des caractéristiques morphotechniques liées au débitage de tels modules, des techniques probables d’extraction et des morphologies observées en relation avec des paramètres fonctionnels. Tous ces points renvoient aux grands thèmes que sont la circulation des matériaux et des objets finis et bien sûr les relations culturelles qui en dérivent.
• Archaeological records of the Mesolithic and Neolithic periods both in terms of change in settlement distribution over time along coasts and hinterlands, and in past dietaries (bioarchaeological remains of animals - invertebrates and vertebrates- as well as geochemical analysis);
• Paleogeographical studies recording geosystem adjustment to sea-level rise (multiple-core analysis, 3D modelling, time-slice reconstruction);
• Paleoecological studies focusing in coastal biotope reconstructions (palynology, aquatic fauna, geochemical analysis);
• Spatial and temporal correlations between archaeological and palaeoenvironmental records of the socio-ecosystem changes;
• Comparisons of European coastal areas (Mediterranean, Atlantic, Baltic, Black Sea) in order to highlight similarities and discrepancies.
Thus, we encourage participation of researchers that are interested in understanding of past human-coastal environment feedbacks during the Early to Mid-Holocene. Ultimately, this session aims to take benefit of past evidences in order to better understand resilience of societies to current global changes.
