Abstract High-altitude island environments, with their characteristic strong seasonal contrast and limited resources, are challenging contexts for human subsistence. However, although archaeological in this kind of setting hold great potential to explore the diversity biological cultural adaptations, such sites rare. In paper, we present results a microcontextual geoarchaeological study carried out at Roques de García Rockshelter, highest altitude cave site Canary Islands (Spain). The was...
Abstract Tar or pitch produced from pine resin and wood played an important role in the past as adhesive, waterproofing medicinal product. However, formation biomolecular composition of tar only under different combustion conditions (i.e., temperature oxygen availability during heating) has not been widely investigated by dry distillation birch bark tar, for which extensive literature is available. This lack information hampers technological interpretations data obtained organic residue...
Abstract Different types of plant tissues and resin can account for the wax lipids found in sedimentary contexts archaeological samples. Consequently, there is increasing research to characterize fatty acid carbon isotope ratios different anatomical parts their exudates (resin). With aim explore isotopic differences between tissues, state fine organic matter, effect thermal degradation, identify residues we measured δ 13 C values short-chain acids (δ 16:0 18:0 ) in: i) dead fresh (collected...
