Validity of radiocarbon ages of Siberian yedoma

GeoResJ, 2017
Abstract The ice wedges are considered as key subjects for 14C aging of yedoma, as there are no any exchange processes between the environment and the ice wedges. Syngenetic sediments contain allochthonous organic admixtures which originated at a distance from its present position.

The role of the Eastern Mediterranean in human evolution: recent results from Greece Le rôle du Bassin méditerranéen oriental dans l’évolution humaine : résultats récents en Grèce

Journal of the Royal Anthropological Institute, EarlyView.
The Eastern Mediterranean lies directly on the principal migration route for human groups dispersing across Africa, Europe, and Asia. It also encompasses the Balkans, where fauna and flora, as well as hominin populations, are thought to have persisted through glacial periods.

New radiocarbon dates from the Bapot-1 site in Saipan and Neolithic dispersal by stratified diffusion [PDF]

, 2010
The colonisation of the Mariana Islands in Western Micronesia is likely to represent an early ocean dispersal of more than 2000 km. Establishing the date of human arrival in the archipelago is important for modelling Neolithic expansion in Island ...

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.

Geochronology of the Upper Ice Complex (Yedoma) exposed in the Batagay Megaslump, East Siberia

Arctic, Antarctic, and Alpine Research
The Batagay Megaslump in eastern Siberia exposes one of the oldest permafrost archives and provides insights into Beringian paleoenvironments. However, its geochronology calls for improvement given known difficulties with permafrost dating and current ...

Improved Radiocarbon Age Estimation Using the Bootstrap [PDF]

Radiocarbon, 1995
This paper proposes the use of the statistical bootstrap technique as an aid in combining radiocarbon date estimates The rationale for the use of the bootstrap is the theoretical result that, even if individual date estimates are normally distributed, their combination by the usual formula results in a random quantity that is not normal but rather a ...
