U-series dating of Paleolithic art in 11 caves in Spain. Paleolithic cave art is an exceptional archive of early human symbolic behavior, but because obtaining reliable dates has been difficult, its chronology is still poorly understood after more than a century of study. The results demonstrate that the tradition of decorating caves extends back at least to the Early Aurignacian period, with minimum ages of These minimum ages reveal either that cave art was a part of the cultural repertoire of the first anatomically modern humans in Europe or that perhaps Neandertals also engaged in painting caves. The timing of archeological industries in the Levant is central for understanding the spread of modern humans with Upper Paleolithic traditions. The dates confirm that the Early Ahmarian industry was present by 46, calibrated years before the present cal BP , and the Levantine Aurignacian occurred at least between 38, and 34, cal BP. This timing is consistent with proposed migrations or technological diffusions between the Near East and Europe.

The Middle to Upper Paleolithic Transition: Dating, Stratigraphy, and Isochronous Markers. Scientific article published on 15 October trends.
PubMed Central. Methodological advances in dating the Middle to Upper Paleolithic transition provide a better understanding of the replacement of local Neanderthal populations by Anatomically Modern Humans. Today we know that this replacement was not a single, pan-European event, but rather it took place at different times in different regions. Thus, local conditions could have played a role. Iberia represents a significant macro-region to study this process.
Northern Atlantic Spain contains evidence of both Mousterian and Early Upper Paleolithic occupations, although most of them are not properly dated, thus hindering the chances of an adequate interpretation. Here we present 46 new radiocarbon dates conducted using ultrafiltration pre-treatment method of anthropogenically manipulated bones from 13 sites in the Cantabrian region containing Mousterian, Aurignacian and Gravettian levels, of which 30 are considered relevant.
These dates, alongside previously reported ones, were integrated into a Bayesian age model to reconstruct an absolute timescale for the transitional period. According to it, the Mousterian disappeared in the region by

She considered the Baltic Magdalenian to date to the end of Allerød and the remains challenging (Eriksen ), although isochronous tephra layers occurring in demonstrate that there are regional lead-lag differences in the transition from stratigraphic resolution poor or non-existent (Vermeersch ; Crombé et al.
Many lines of evidence point to the period between roughly 40 and 30 ka BP as the period in which modern humans arrived in Europe and displaced the indigenous Neandertal populations. At the same time, many innovations associated with the Upper Paleolithic–including new stone and organic technologies, use of personal ornaments, figurative art, and musical instruments–are first documented in the European archaeological record.
Dating the events of this period is challenging for several reasons. In the period about six to seven radiocarbon half-lives ago, variable preservation, pre-treatment, and sample preparation can easily lead to a lack of reproducibility between samples and laboratories. A range of biological, cultural, and geological processes can lead to mixing of archaeological strata and their contents.
Additionally, some data sets point to this period as a time of significant spikes in levels of atmospheric radiocarbon. We conclude that variable atmospheric radiocarbon production contributes to the problems of dating the late Middle Paleolithic and the early Upper Paleolithic. To help establish a reliable chronology for the Swabian Aurignacian, we are beginning to focus our dating program on short-lived, stratigraphically secure features to see if they yield reproducible results.
This approach may help to test competing explanations for the noisy and often non-reproducible results that arise when trying to date the transition from the Middle to the Upper Paleolithic. Tags Type your tag names separated by a space and hit enter. J Hum Evol.

This paper critically reviews the culture-historical framework for the re-colonisation of Lithuania during the Final Palaeolithic in the light of recent palaeoclimatic and palaeoenvironmental data. We argue that the existing chronology of the Final Palaeolithic in Lithuania suffers from an undue western European orientation grounded in research history, and that it likely requires reconsideration. The lack of well-constrained excavations, the paucity of both radiocarbon dates and of palaeoenvironmental data pertinent to the Last Glacial-Interglacial Transition LGIT lead us to be cautious with regard to the existing chronology.
In reviewing the typological classification of the relevant lithic material, we argue in particular that there is a lack of reliable evidence not only for Hamburgian occupation but also for any substantive Federmessergruppen, Brommean and Ahrensburgian presence. Whilst Swiderian sites are better represented, a large majority of these may date to the early Holocene.
In light of the current evidence, we question the usefulness of existing archaeological taxonomies for this period and favour a model of punctuated colonisation for the Lithuanian territory, where periodic and ephemeral forager presences are interspersed with longer periods of depopulation.

To celebrate our appearance at the first Independent Bath Market more on that here , we asked Instagrammer, Alixe Lay, to take over our Instagram account and share her 3 favourite spots from the beautiful city of Bath. A: I grew up in Malaysia and came to live in Bath about three and a half years ago to pursue a degree in Psychology.
I have a love-hate relationship with London — I love the vibrance, the buzz, the never-ending list of places to visit and dine in, but hate the crowds and the pollution. R: Architecture seems to play a big role in the photos you take – do you have a favourite architectural style or period? A: Hah, did I fool you?

Arctic landscape evolution and long-term coastal change Poster Only. This session invites contributions dealing with long-term changes in coastal environments in the Arctic and the relevant processes that govern late Quaternary and Holocene landscape evolution. Coasts in the polar regions are at present rapidly changing under the influence of a pronounced climate warming trend. This induces erosion due to the retreat of sea ice, the increase of wave forcing along coasts and a general susceptibility of thawing permafrost shorelines.
Long-term rates of carbon and nutrient release, patterns of dynamic coastal geomorphological change, studies of sedimentary archives of past environments such as beach ridges or coastal lakes, and investigations into past sea-level change are topics that help to understand the functioning and response of modern Arctic coasts to climate change. The coastal environment is here considered in a wide definition of landscapes located at the land-sea transition, including terrestrial and shelf sea environments that have e.
Thematically, this session is placed between Quaternary geology and Holocene coastal geomorphology and aims at contributions looking into sedimentary archives, climate forcing, coastal erosion, or the release of organic matter and sediment over decadal to millennial time scales. Contributions by early-career researchers are highly encouraged as well as interdisciplinary studies looking into the biological responses to coastal change and biogeochemical cycling. Back to the future: Submerged shorelines on the shelf as tools for climate, sea-level and future shoreline reconstructions.
Given the context of changing climates and the increasing threat to coastal areas from increasing rates of sea-level rise, it has become increasingly important to understand the manner in which coastal systems and their shorelines may respond to future sea level rises.
