Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

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 ...

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

Lethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Biometric Analysis of Giant and Large Murid Remains From Matja Kuru 2, Timor‐Leste

Archaeometry, EarlyView.
ABSTRACT Published research on Matja Kuru 2 (MK2) demonstrates its significance for understanding human lifestyle during the terminal Pleistocene and Holocene. Murids represent the most commonly identified taxa in the site, with specimens preliminarily classified as small, large and giant based on size comparisons.
