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 ...

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions
Archaeometry, EarlyView.ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Archaeometry, EarlyView.ABSTRACT Human skeletal remains constitute critical archaeological evidence for reconstructing past societies, yet their investigation requires careful ethical, cultural, and legislative consideration. This paper reports on the discovery, recovery and analysis of a set of skeletal remains encountered during a cultural heritage management (CHM ...

Amino acid racemization dating: Method development using African ostrich (Struthio camelus) eggshell [PDF]
, 2013 Ostrich eggshell (OES) is ubiquitous in archaeological sites in Africa and is a favoured substrate for amino acid racemisation (AAR) geochronology, yielding consistent results and thought to approximate a closed system with respect to protein diagenesis.

High field strength element systematics and Lu-Hf & Sm-Nd garnet geochronology of orogenic eclogites [PDF]
, 2008 Concerning the Bulk Silicate Earth (BSE), the depleted mantle and the continental crust are thought to balance the budget of refractory and lithophile elements, resulting in complementary trace element patterns.
