Living by the lake: Plant food diversity in a prehistoric lake‐dwelling community in the Republic of North Macedonia

open access: yesArchaeometry, EarlyView.
Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...

Levantine Hacksilber and the flow of silver in early Mediterranean commerce

open access: yesArchaeometry, EarlyView.
Abstract This study presents a comprehensive approach to provenancing ancient silver artefacts, introducing a novel algorithm to correct for mass‐dependent isotope fractionation. Applied to a Pb isotope database of 281 Hacksilber samples from southern Levantine hoards (1700–600 BCE) and compared with approximately 7000 galena ores from Spain to Iran ...

Food web reconstruction of Barmaky, the oldest post‐LGM hunter‐gatherer site in north‐western Ukraine

open access: yesBoreas, EarlyView.
The site of Barmaky currently marks the oldest Epigravettian occupation of north‐western Ukraine shortly after the Last Glacial Maximum (LGM), dated to around 19 cal. ka BP. Stable isotope analyses of bone collagen from six terrestrial mammals and two bird species show a comparatively highly structured palaeo‐food web.
