Hair Degradation Patterns in Aquatic and Soil Environments

Archaeometry, EarlyView.
ABSTRACT Hair is a biological material that can provide information in archaeology and forensics. Previous studies have mainly examined changes occurring post‐mortem. In this study, we focused on hair pulled out ante‐mortem. The aim of the study was to identify patterns in the degradation of hair in water and soil.

Between Gaps and Voids: An Archaeometrical Study of Degraded Fibers in a Sherd From the Cueva dos Chinches Muertas, Siltzul (Raxruha, Alta Verapaz, Guatemala)

Archaeometry, EarlyView.
ABSTRACT In 2019, excavations at the Cueva dos Chinches Muertas carried out by the Raxruha Viejo Project uncovered a small ceramic sherd distinguished by a stratified structure composed of multiple layers of textile imprints, both superficial and transversal.

Geomagnetic Intensity of Hellenistic Pottery and Stamped Rhodian Wine Amphorae From Jerusalem

Archaeometry, EarlyView.
ABSTRACT Stamped amphora handles produced on Rhodes during the Hellenistic period are well suited for archaeointensity studies because they often bear the names of annually appointed magistrates (eponyms) and fabricants, allowing dating to narrow time intervals.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.
