Micro-archaeological data from sites located in central and eastern Europe show that, in comparison with other Upper Paleolithic hunter-gatherers, Gravettian foragers used fire more intensively and for a wider range of purposes. In these regions, this shift in pyrotechnology overlaps with the onset of periglacial conditions and comparable micro-archaeological datasets from milder regions, such as Cantabria, remain scarce. As result, it is difficult to conclude whether these fire behaviors were cultural traits of the Gravettian tradition, or whether they reflect adaptations to regional environments. To further investigate these hypotheses, we studied the sequence preserved at the cave of Fuente del Salín, in Cantabria, where previous excavations unearthed potential fire residues of Gravettian age. Using micromorphology, µ-X-ray fluorescence, and Scanning Electron Microscopy we reconstructed multiple phases of human visits to the site. Our results show that, during the main Gravettian occupation, foragers made intensive use of fire, as indicated by abundant heated bones and seashells, charcoals, amorphous char, fat-derived char, and in situ remains of stacked open hearts as well as burnt grass beddings. The intensive burning, systematic reuse of combustion features, and multiple purposes of the fires at Fuente del Salín are comparable with Gravettian sites from central and eastern Europe, indicating that these fire-use traits were not related with periglacial environments but with lifeway aspects and traditions of Gravettian hunter-gatherers.

Micro-archaeological data from sites located in central and eastern Europe show that, in comparison with other Upper Paleolithic hunter-gatherers, Gravettian foragers used fire more intensively and for a wider range of purposes. At these sites, this shift in pyrotechnology overlaps with the onset of periglacial conditions. Gravettian occupations of non-periglacial regions have been poorly investigated with micro-archaeological methods, and it remains to be further demonstrated whether these foragers also made a similar intensive and multipurpose use of fire. To further investigate this topic, we studied the sequence preserved at the cave of Fuente del Salín, in Cantabria, where previous excavations unearthed potential fire residues of Gravettian age. Using micromorphology, µ-X-ray fluorescence, and Scanning Electron Microscopy we reconstructed multiple phases of human visits to the site. Our results show that, during the main Gravettian occupation, foragers made intensive use of fire, as indicated by abundant heated bones and seashells, charcoals, amorphous char, fat-derived char, and in situ remains of potential stacked open hearths as well as burnt grass beddings. The intensive burning, systematic reuse of combustion features, and multiple purposes of the fires at Fuente del Salín are comparable with Gravettian sites from central and eastern Europe, indicating that these fire-use behaviors probably do not reflect a regional adaptation to periglacial environments but a cultural trait of the Gravettian tradition across Europe.

Quaternary fluvial carbonate deposits of the Almonda River Valley, Central Portugal

This paper discusses the formation and preservation of a fluvial tufa system influenced by Atlantic climate based on stratigraphical, chronological (amino-acid racemization, AAR), sedimentological and stable-isotope analyses. On the southwestern Iberian Peninsula, the tufas and associated deposits of the Almonda River valley occur as isolated terraced bodies and reach 25 m thick. AAR dated most deposits to within the warm Marine Isotope Stage 5 (MIS-5). Two Holocene ages were reset within MIS-5 based on diverse criteria. Widely varied carbonate and minor allochthonous coarse detrital facies occur arranged in four simple vertical associations. The deposit geometry and facies association distribution correspond to a low- to moderate-sloped fluvial valley consisting of several short knickpoints and extensive flat areas between them. The latter are occupied by slow-flowing water facies (carbonate sand, lime mud, phytoclast and oncoid rudstones, and up-growing stem boundstones). Facies that formed in moderate- to high-slope substrates were stromatolite, moss and down-growing stem boundstones. The homogeneous Miocene bedrock lithology and gentle structural deformation propitiated this depositional architecture. Calcite δ13C and δ18O values suggest that the aquifer water provided the outflowing Almonda water with (1) 18O-enriched water, compared with present precipitation and groundwater δ18O values, and (2) 13C-depleted CO2 from bituminous rocks and vegetation cover in the catchment. The proximity to the Atlantic coast favoured the Mesozoic-rock aquifer recharge with 18O-enriched water precipitation, assuring water availability during the formation of the studied tufas. No evidence of frequent intense erosion phases might indicate stable precipitation regimes, which would have allowed the preservation of loose fine-grained and palustrine deposits.
