Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

Archaeometry, EarlyView.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

Archaeometry, EarlyView.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

Archaeometry, EarlyView.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.
