<jats:title>Abstract</jats:title><jats:p>The Salado and Verde streams constitute the two main seasonally available freshwater courses that flow into the Atlantic coast of the Río Negro province (continental Patagonia, Argentina, 42° South). This would have favored their use in the past as corridors for human circulation between the coast and the interior. This paper presents the results of the techno‐morphological and geochemical analyzes of the obsidian artifacts recovered in the area to constrain mobility. The results allow us to propose the existence of toolkit reconditioning or replacement activities and the identification of different sources of provenance of the obsidians (Sacanana, Telsen and Portada Covunco, distant up to 800 km from the study area), reinforcing the hypothesis of a coast‐inland circulation, with the possible existence of circuits of exchange of this raw material.</jats:p>

<jats:title>Abstract</jats:title><jats:p>The Middle Nile Valley offers exceptional environmental conditions that allow the preservation of organic materials, including textiles. This paper presents the results of the analysis of 17 samples collected from wool, cotton, and silk textiles excavated in the ancient capital of Old Dongola from layers dated to the 17th and 18th centuries <jats:sc>CE</jats:sc>. Chemical analysis using high performance liquid chromatography coupled with mass spectrometry (HPLC‐MS/MS) have identified both plant and animal dyes. Locally produced textiles, mostly from wool and decorated with blue, green, orange, and yellow hues, were dyed with woad (<jats:styled-content style="fixed-case"><jats:italic>Isatis tinctoria</jats:italic></jats:styled-content>), flavonoid plants, and madder‐type roots, which were already known and used by medieval dyers in that area. For the first time, kermes (<jats:italic>Kermes vermilio</jats:italic>) and lac‐dye (<jats:italic>Kerria</jats:italic> species) have been also identified as a dye source in samples from this group. Imported fabrics, of cotton and silk, were dyed blue with woad (<jats:styled-content style="fixed-case"><jats:italic>I. tinctoria</jats:italic></jats:styled-content>) but also with indigo (<jats:styled-content style="fixed-case"><jats:italic>Indigofera tinctoria</jats:italic></jats:styled-content>); dyer's broom (<jats:styled-content style="fixed-case"><jats:italic>Genista tinctoria</jats:italic></jats:styled-content>) and kermes (<jats:italic>K. vermilio</jats:italic>) were other dyes identified in this second group. The results of this study provide the first dye identification for textiles produced in the 17th–18th c. Sudan and contribute new data to the research on textile production and trade in post‐medieval Sudan.</jats:p>
