A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

Journal of Quaternary Science, EarlyView.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

Journal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Revisiting Gubbio: Settlement Patterns and Ritual from the Middle Palaeolithic to the Roman Era

Land
The Gubbio Revisited project, initiated to reinterpret the archaeological evidence collected during the 1980s Gubbio Project, primarily by a conversion from a paper to a digital record, has revealed significant insights into the evolving settlement ...

Stratigraphy and chronology of a 15ka sequence of multi-sourced silicic tephras in a montane peat bog, eastern North Island, New Zealand. [PDF]

, 1999
We document the stratigraphy, composition, and chronology of a succession of 16 distal, silicic tephra layers interbedded with lateglacial and Holocene peats and muds up to c. 15 000 radiocarbon years (c.

Skeletal Dysplasia During the Bronze Age in Northeast Thailand (3000–2500 BP)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study examines a case of skeletal dysplasia in an adult male (B290) from the Bronze Age at the site of Ban Non Wat, Northeast Thailand. Skeletal dysplasia, a group of genetic disorders affecting bone and cartilage growth, presents diagnostic challenges due to overlapping clinical features.

Burial and Origin of Permafrost‐Derived Carbon in the Nearshore Zone of the Southern Canadian Beaufort Sea

Geophysical Research Letters, 2020
Detailed organic geochemical and carbon isotopic (δ13C and Δ14C) analyses are performed on permafrost deposits affected by coastal erosion (Herschel Island, Canadian Beaufort Sea) and adjacent marine sediments (Herschel Basin) to understand the fate of ...

A new model of cosmogenic production of radiocarbon 14C in the atmosphere

, 2012
We present the results of full new calculation of radiocarbon 14C production in the Earth atmosphere, using a numerical Monte-Carlo model. We provide, for the first time, a tabulated 14C yield function for the energy of primary cosmic ray particles ...

Stable Carbon and Nitrogen Isotope Analysis Explores Diverse Domestic Goose Management Practices in Medieval and Postmedieval Russia

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Studying goose domestication through archaeological finds has been challenging due to the similar skeletal morphology of the European domestic goose and its wild progenitor, the greylag goose (Anser anser). We analyzed stable carbon (δ13C) and nitrogen (δ15N) isotopes from bone collagen of subfossil domestic and potentially domestic geese to ...

Les datations radiocarbone du Tardigravettien ancien à crans de l’abri de Chinchon 1 à Saumane‑de‑Vaucluse et la chronologie du Paléolithique supérieur récent provençal

Gallia Préhistoire, 2016
The lithic industry with shouldered points and truncated backed bladelets from the rockshelter of Chinchon 1 in the Vaucluse has been variously interpreted over the past few decades : some authors clearly see it as belonging to an ultimate, classic ...
