The Materiality of the Cloggs Cave Rockshelter's Painting, GunaiKurnai Country (East Gipplsland), Southeastern Australia

open access: yesArchaeometry, EarlyView.
ABSTRACT The materiality of the white pigment motif at the Cloggs Cave rockshelter, near Buchan in GunaiKurnai Country (southeastern Australia), contains details about the cultural and environmental contexts in which the art was created and preserved. Here, we (1) present physicochemical analyses of the pigment composition; (2) explore implications for

Safety pharmacology of acute mescaline administration in healthy participants

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Psychedelics, including mescaline, may serve as novel treatments for depression and anxiety. However, data is scarce on the safety of mescaline. Methods The present pooled analysis included two double‐blind, randomized, placebo‐controlled studies with a total of 48 participants and 96 mescaline administrations. Single oral‐dose administrations (n =

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

open access: yesBoreas, 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.

Pitfalls in the calibration of radiocarbon ages

open access: yesJournal of Nordic Archaeological Science – JONAS
The further back the calibration of the radiocarbon time-scale extends, the more it will be used. Calibration is not simple, however, and it may even lead to erroneous conclusions unless certain precautions are taken. Confusion may be caused by the use of different symbols for citing dating results, ages based on different half-lives, and incorrect ...

The Early Upper Palaeolithic open‐air site of Friedrichsdorf‐Seulberg, Germany, in the context of the northern central European Aurignacian

open access: yesBoreas, EarlyView.
Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...

Purification of hydroxyproline for small-scale radiocarbon dating verified using archaeological bone collagen

open access: yesProgress in Earth and Planetary Science
We developed a novel technique for the accurate radiocarbon dating of single amino acids from archaeological human and animal remains. Despite the extensive use of bulk collagen for radiocarbon dating of archaeological bones, obtaining accurate dates can

Environmental dynamics and timing of the late Eemian interglacial to the Weichselian pleniglacial at Lichtenberg, Germany: implications for the Oerel and Glinde interstadials

open access: yesBoreas, EarlyView.
The terrestrial sediment archives of northern Germany provide important insights into Late Pleistocene climate variability, but continuous and well‐dated records remain rare. In particular, the age and stratigraphic position of the Oerel and Glinde interstadials within the Early Weichselian to pleniglacial transition remain poorly constrained.

Early to Mid‐Holocene molluscan community dynamics in Billefjorden, central Svalbard: the interplay of local geomorphology and regional climate

open access: yesBoreas, EarlyView.
The postglacial evolution of High Arctic coastal environments is recorded in the rich fossiliferous archives of raised marine terraces. This study employs a multi‐proxy approach combining molluscan community analysis, taphonomy and sedimentology to reconstruct the Early to Mid‐Holocene environmental dynamics of the Mimerdalen embayment in the ...
