Bokkapitel (refereegranskat)abstract
- The article summarizes the results of work since 2010 to develop non- destructive energy dispersive X-ray fluorescence analysis (EDXRF) as a non-destructive method for determining the provenience of flint in northern Europe. Some 40 localities from Sweden, Denmark, Germany, Poland, and Ukraine have been sampled and analyzed. Trace elements have not proven particularly effective in drawing distinctions between and among flint and chert because they often occur below, or near, detection limits. However CaO and Fe compositions usually generated the highest count rates and total counts using EDXRF and their concentrations allowed satisfactory partitioning of some of the flints we analyzed. EDXRF can help us to discriminate among various outcrops of flint used for tool production during prehistory. Future work involves investigating correlations between flint chemistry and visual appearance, as well as investigating source-critical aspects of post-depositional effects on tool surfaces.

- We investigated the genetic composition of six Canis remains from western Iberia, directly radiocarbon dated to 7,903-7,570 years (cal BP). They were identified as dogs via their archaeological and depositional context, osteometry, and a high percentage of aquatic diet shared with humans. For comparison, genetic data were obtained from an additional 37 Iberian dog remains from the Neolithic to Late Antiquity, as well as two Palaeolithic and a Chalcolithic Canis identified as wolves. Previous data indicated that dog mtDNA haplogroup A (HgA) is prevalent in extant European dogs ( > 50%), in the Near East and Asia, but rare or absent ( < 10%) in European Canis older than 3,000 years (cal BP). We found a high frequency (83%) of dog HgA in Mesolithic Iberian dog remains. This is the first report of a high frequency of dog HgA in pre-Neolithic Europe. We show that, contrary to the current view, Canis with HgA did not necessarily arrive in Europe from East-Asia. This phylogeographical difference in HgA frequency demonstrates that genetic differentiation was high prior to, or as a consequence of, domestication which may be linked with pre-Neolithic local processes for Iberian wolf domestication. Our results emphasize that knowledge of both ancient wolves' and early dogs' genetic profiles from the European periphery should improve our understanding of the evolution of the European dog.

Konferensbidrag (refereegranskat)abstract
- Research on the sourcing of siliceous raw materials in Prehistory has taken a step forward with the addition of geochemical techniques and elemental analysis to the archaeopetrological method. Counter to the macroscopic techniques, which retain an elevated subjective percentage in their results, geochemical techniques and especially LA-ICP-MS analysis generate objective, quantifiable and usable data, helping us to complete another mineralogical analysis.95% of the siliceous raw material from the Hort de la Boquera archaeological site (Margalef de Montsant, Tarragona, Spain) is a type of flint from an evaporitic origin that petrografically is characterized by a chalcedonic matrix with gypsum lenticules as inclusions.Siliceous Raw Material Exploitation at Hort De La Boquera Site 235Multiple flint outcrops from an evaporitic origin (Eocene-Oligocene) and with many closed characteristics such as the lithic raw material from Hort de la Boquera are located near the site (Cornudella Group-Ulldemolins Complex), making them very suitable to supply the inhabitants of the Hort de la Boquera site.We have two different but complementary goals in this research: on the one hand, to characterize, describe and create a database for all the different types of flint recovered, emphasizing their geochemical marks. On the other hand, we have the aim to compare these results with those obtained from the raw materials recovered at the site, which would provide a range of complementary data to discover the potential catchment areas and help us to understand certain behaviours of the prehistoric communities from the Hort de la Boquera site.
