Stratigraphic Unit 13 of Oscurusciuto Rockshelter (Ginosa, Taranto, Southern Italy) is a short Mousterian palimpsest representing the first stable occupation of the site soon after the deposition of ...a thick layer of tephra (Mt. Epomeo Green Tuff - Ischia datable around 55 kya BP).
Different activities were identified by integrating the study of lithic finds, faunal remains, and the microarchaeology of combustion features. Additionally, geo-statistical analysis of these data has been carried out using a specifically designed geodatabase within a GIS platform.
Our results produced an articulated picture of this Neanderthal site as a tripartite location made of spatially segregated and integrated activity areas. A hearths' alignment (parallel to the rockshelter wall) divides the settled area into an inner and outer part. The inner part, between the hearths and the shelter wall, displays an abrupt rarefaction of the anthropic finds and was interpreted as a possible sleeping/resting area. In the outer part, several multipurpose activity areas have been identified, mostly associated with the combustion features. The Northern sector of the settlement appears devoted particularly to lithic production (to a lesser degree, activities related with lithic tools use and faunal processing took place). In the Southern sector the main activities carried out represent more intensive production and use of lithic tools and the butchering and consumption of animal resources. Additionally, in this sector evidence of space maintenance behaviour (cleaning up of working areas and refuse dumping) has been attested.

This study represents the first integrated approach to the lithic raw materials exploited by the Neanderthals that occupied the Abric Romaní site (NE Iberia). Focusing on chert as the most abundant ...raw material (>80% of the assemblages), we determine the potential procurement areas and the mobility patterns. Geo-archaeological surveys within a radius of 30 km from the site documented 32 primary locations with silicifications. The chert abundance ratio, a quantitative approach to the raw material availability, together with macroscopic and petrographic analyses, confirm the underexploitation of the local raw materials (<10 km).
The main procurement areas are located between 16 km (Sant Martí de Tous chert) and 24 km (Panadella chert), indicating different procurement strategies and mobility patterns. Stone tool assemblages from levels M and Oa fall within a foraging radius, whereas level P, in part, suggests a logistical radius, demonstrating a complex scenario of extensive knowledge and intensive exploitation of the landscape among Neanderthals.
•Landscape exploitation and mobility among Neanderthals at Abric Romaní (NE Spain).•Petrologic analyses and statistics models determine the stone tools provenance.•Results suggest a regional range for procurement, denying the distance-decay model.•Different mobility strategies are detected independently of technological constraints.•Behavioral complexity based on group size, occupation duration and/or site function.

The interior of the Iberian Peninsula has few Middle Palaeolithic sites, especially when compared to other areas of the Mediterranean Basin and the northern Spanish region. Few in number too are the ...zooarchaeological and taphonomic studies that throw light on the relationships between Neanderthal groups, their environment, and the use they made of it. The present work examines, both zooarchaeologically and taphonomically, the faunal remains of levels F and D of the Navalmaíllo Rock Shelter (Pinilla del Valle, Madrid, Spain) - the largest collection of such remains ever studied from the Iberian interior. The results allow this site to be interpreted as a Neanderthal hunting camp where occupations were short-term. Neanderthal people were the main agents that accumulated the site's faunal remains - largely those of large bovids and to a lesser extent medium-sized cervids. The activity of carnivores was also identified, but these animals mostly left behind the remains of small prey or fed upon carcasses abandoned at the camp by human hunters.
•Navalmaíllo Rock Shelter has been interpreted as a Neanderthal hunting camp.•All phases of butchery were identified, along with the extraction of bone marrow.•Bovines and cervids are the more common taxa in the assemblage.•There is a low degree of competition between hominins and large carnivores.•The faunal assemblage was little affected by post-depositional processes.

This paper presents a multiproxy palaeoenvironmental study from Abric del Pastor (Alcoy, Spain), a rock shelter which has yielded evidence for Middle Palaeolithic human occupation. The sedimentary ...sequence has been analysed for lipid biomarker n-alkane abundances (ACL, CPI), compound specific leaf wax δ2H and δ13C, and bulk organic geochemistry (TOC, %N, %S), providing a record of past climate and local vegetation dynamics. Site formation processes have been reconstructed through the application of soil micromorphology. Analyses of anthracological, microvertebrate and macrofaunal assemblages from selected subunits are also presented here. Our data indicates that a variable climate marked by predominantly cold conditions persisted through most of the sequence and that Neanderthal occupations in stratigraphic unit IVd, assigned to MIS 4 or late MIS 5, occurred in a landscape setting characterised by a mosaic of biotopes. The presence of key resources inside the ravine where the site is located suggests that the occupation of the rock shelter may have been strategically motivated by a subsistence and mobility strategy which focused on zones of localised ecological resilience, such as intra-mountainous valleys or ravines, during periods of global or regional environmental downturn.
•New palaeoenvironmental data for Neanderthal site of Abric del Pastor is presented.•Degradation of n-alkanes linked to anthropogenic fire.•Occupations in S.U. IVd occurred in generally cold and dry conditions.•The Barranc del Cinc acted as a vegetation refugium.•Occupation of rock shelter may have been strategically motivated by its location.

Based on previous radiocarbon and U-series (Diffusion/Adsorption) dating of bone samples, the Middle Palaeolithic has been thought to persist at Gruta da Oliveira until ∼37 thousand years (ka) ago. ...New U-series ages for stratigraphically constraining speleothems, coupled with new luminescence ages for sediment infill, show that the site’s ∼6 m-thick archaeological stratigraphy dates entirely within a <30 ka interval spanning substages 5a-5b of Marine Isotope Stage (MIS) 5. Significant technological change is observed across the sequence, akin to that seen in the Upper Palaeolithic over similar timescales. Flake-cleavers and bifaces, normatively definitional of the Vasconian facies, are restricted to a short interval correlated with Greenland Stadial (GS) 22, 85.1–87.6 ka ago. In cave and rock-shelter sites of southern and western Iberia, intact archaeological deposits securely dated to the ∼37–42 ka interval remain elusive. Geological dynamics (e.g., erosion, sedimentation hiatuses, palimpsest formation) and human adaptive responses to climate-driven environmental change (e.g., abandonment of now forest-covered low- and mid-altitude karst areas, concentration of settlement in alluvial plains and coastal settings) are possible explanations for this pattern.

The timing, duration and evolution of sea level during the Marine Isotope Stage 5e (MIS 5e) highstand is a subject of intense debate. A major problem in resolving this debate is the difficulty of ...chronologically constraining the sea level fall that followed the peak of the highstand. This was mainly controlled by ice-sheet dynamics, the understanding of which is relevant for assessing future sea-level behavior due to global warming. Here we use stratigraphical and geochoronological (U/Th dating and tephra fingerprinting) evidence from the Infreschi archaeological cave (Marina di Camerota, Southern Italy) to constrain relative sea level (RSL) evolution during the MIS 5e highstand and younger stages. Uranium-thorium dating of speleothem deposition phases places the maximum highstand RSL at 8.90 ± 0.6 m a.s.l., as indicated by the near-horizontal upper limit of Lithophaga boreholes measured for along a ∼3.5 km coastal cliff section. Geochronological data show that RSL fell more than 6 m before ∼120 ka, suggesting a duration of the Last Interglacial highstand significantly shorter than proposed in some previous studies. Modelling shows that the RSL trend predicted by the ICE-5G and ICE-6G ice-sheet simulations is consistent with our data, but requires an additional significant reduction of both Greenland and Antarctic ice sheets to match the height of the local maximum highstand if no correction for tectonics is applied. Reconciling field data and models requires an earlier and likely shorter duration of the MIS 5e highstand. This suggests that our new data can constrain global ice-volume variations during the penultimate deglaciation, as well as glacial inception at the end of the Last Interglacial. According to our chronology, there is no local evidence of higher-than-present-day sea levels after 120 ka.
•Infreschi cave data indicate that maximum highstand during MIS5e was ca. 8 m asl.•Infreschi cave data indicate RSL dropped of more than 6 m before 120 ka.•Infreschi cave data indicate that there is no evidence of RSL higher than present after 120 ka.

The emergence of the Upper Palaeolithic in Southwest Asia is considered a unique phenomenon in relation to other parts of the Old World. Besides the local circumstances that are particular to each ...region, this is the only region outside Africa with the clear presence of modern humans producing Middle Palaeolithic industries. Still, it seems that also here, as elsewhere outside Africa, the UP is conceived mostly as portraying a break with MP life-ways, and continuity, if indicated, is on a rather modest scale.
While the geographical extent of the Levant (i.e. the eastern Mediterranean, from the Taurus Zagros mountains in the north, to southern Sinai and from the coast eastwards of the Rift valley into the Saudi Arabian deserts) is relatively small, at least four or five variants of Initial Upper Palaeolithic lithic industries have been identified/defined, based on techno-typological criteria, geographical constraints and differing chronologies, as demonstrated at Boqer Tachtit, Tor Sadaf, Ksar Akil, Umm el-Tlel, and Ucagizli.
Besides the usual obstacles archaeologists face in trying to identify and define relationships between various archaeological assemblages in time and space, prehistoric research of the Levant, like other regions, suffers from its Eurocentric past and international present, whereby research reflects the different ‘weltanschauung’ and paradigms of the scholars currently conducting it.
We shall attempt to present a coherent picture of the present state of affairs, as well as our own understanding of the Levantine IUP, based on the locally available data within the wider context of current prehistoric research.

Excavations for the construction of thermal pools at Poggetti Vecchi (Grosseto, Tuscany, central Italy) exposed a series of wooden tools in an open-air stratified site referable to late Middle ...Pleistocene. The wooden artifacts were uncovered, together with stone tools and fossil bones, largely belonging to the straight-tusked elephant Paleoloxodon antiquus. The site is radiometrically dated to around 171,000 y B.P., and hence correlated with the early marine isotope stage 6 Benvenuti M, et al. (2017) Quat Res 88:327–344. The sticks, all fragmentary, are made from boxwood (Buxus sempervirens) and were over 1 m long, rounded at one end and pointed at the other. They have been partially charred, possibly to lessen the labor of scraping boxwood, using a technique so far not documented at the time. The wooden artifacts have the size and features of multipurpose tools known as “digging sticks,” which are quite commonly used by foragers. This discovery from Poggetti Vecchi provides evidence of the processing and use of wood by early Neanderthals, showing their ability to use fire in tool making from very tough wood.

One of the major challenges in scientific research is to understand past climate and the mechanisms of climate change. Small vertebrates, and especially rodents, are very sensitive to shifts in ...climate and habitat, and their variations over time in terms of taxa and abundance can be successfully used to reconstruct past environments. The vast array of approaches to palaeoclimatic reconstruction reflects the great effort that has gone into this line of investigation. Recently, the UDA-ODA discrimination technique has been postulated as a more reliable ecologically-based methodology compared to the classical MER method.
To provide biogeographical information to be analysed by the UDA-ODA discrimination technique, the distributions of four species (Sorex minutus, Chionomys nivalis, Talpa europaea and Crocidura russula) documented in levels O, N, E and D of the Abric Romaní site were processed. The results reveal a statistical difference between the climatic values for the occupied distribution areas (ODA) and those for the uncertain distribution areas (UDA). This technique was then applied to small-mammal assemblages from the above-mentioned levels of Abric Romaní, to test whether the use of the ODAs of the species improves the precision of the climatic reconstruction compared to the atlas distributions of the species used in MER procedures. Our results suggest an improvement in the discrimination analysis over the previous MER reconstructions when wider distributions for an assemblage are obtained. The coldest values obtained for level O of Abric Romaní seem to reinforce the pollen interpretation of the level as coetaneous with a cold period. For the whole MIS 3 climatic scenario for Neanderthals, a colder and wetter climate is derived from the small-mammal analysis. However, as different methods and analyses have inherent limitations, a standardization of the methods applied to the different levels and sites should be carried out in order to provide comparable results.
•Species' ODAs from Abric Romaní got more accurate climatic results only in level D.•Wider mutual distributions imply high probability of precision with ODAs.•Consistency between methods is observed in the climatic tendency along the sequence.•A cold and wet scenario is deduced from the different proxies and methods applied.

Most archaeological and palaeo-environmental archives are preserved in specific environments (buried sediments, rock shelters, cave environments). Hence, the information we can obtain is usually ...incomplete, and lacking spatial and morphological significance. Studying landscape evolution can help us to understand the location and distribution of past societies and their relation to Quaternary environments. In the Ardèche Valley, most Middle and Late Palaeolithic sites are preserved in caves and rock-shelters and in rare cases in fluvial sediments. Here we apply an integrated geomorphological approach to the study of the evolution of the Ardèche Valley combining multi-method dating, geomorphological mapping and surveys of cave and fluvial formations. We review chronological results obtained through multi-method dating (electron spin resonance (ESR), infrared stimulated luminescence (IRSL), uranium-series (U-series), combined electron spin resonance/uranium-series (ESR/U-series)) on cave and riverine objects and combine them with topographic and stratigraphic observations in an integrated Bayesian hierarchical model. The results are in agreement with those obtained from other rivers in mountainous environment around the Mediterranean Sea and show sedimentation/incision phases that match the 100 ka glacial/interglacial cycles. The mean rate of river incision deduced from the established chronology for the Middle and Late Pleistocene period, 76 ± 7 m.Ma−1, shows adjustments to a moderate uplifting dynamic that shaped the main topographical features seen today in the landscape of the Ardèche Gorge. The spatially reconstructed alluvial features provide a palaeogeographic framework that can be used directly as a chronological and topographical constraint for archaeological research in the Ardèche catchment.
•We review Middle and Late Pleistocene landscape evolution in the Ardèche valley.•80 ages are discussed together with 13 new U-series ages.•Ardèche fluvial evolution follows a climate-induced 100 ka cyclicity.•Relevant landscape transformations appeared during the Middle and Late Palaeolithic occupation.
