Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-10 (2022)
Here the authors demonstrate the use of zinc isotopes (δ66Zn) to geochemically assess trophic levels in extant and extinct sharks. They show that the Neogene megatooth shark (Otodus megalodon) and the great white shark (Carcharodon carcharias) occup

Description
Subarctic climate at an early H. sapiens site in Europe shows that expansion of our species was not predicated on warm climates.
The expansion of Homo sapiens across Eurasia marked a major milestone in human evolution that would

Oxygen isotopes in bioarchaeology: Principles and applications, challenges and opportunities
Autor: Sarah Pederzani, Kate Britton
Publikováno v: Earth-Science Reviews. 188:77-107
Oxygen isotope analyses of skeletal remains (18O/16O, δ18O) are a powerful tool for exploring major themes in bioarchaeology (the study of biological archaeological remains) and can aid in the reconstruction of past human-environment interactions, s

Oxygen (δ18O) and carbon (δ13C) isotopic distinction in sequentially sampled tooth enamel of co-localized wild and domesticated caprines: Complications to establishing seasonality and mobility in herbivores
Autor: Cheryl A. Makarewicz, Sarah Pederzani
Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 485:1-15
Dietary intake, drinking behavior, and physiology together influence the isotopic composition of herbivore tooth enamel, but the degree to which these factors influence the sequence of δ 13 C and δ 18 O values along the tooth crown remain underexpl

Oxygen isotope analysis of Equus teeth evidences early Eemian and early Weichselian palaeotemperatures at the Middle Palaeolithic site of Neumark-Nord 2, Saxony-Anhalt, Germany
Autor: Sabine Gaudzinski-Windheuser, Lutz Kindler, Sarah Pederzani, Kate Britton, Michael P. Richards, Thomas Tütken, Wil Roebroeks
Here we present phosphate oxygen isotope (δ 18OPO4) data from horse (Equus sp.) tooth enamel (bioapatite) from early Eemian and early Weichselian find levels at the archaeological site of Neumark-Nord 2, Germany. Based on the relationship between δ

Publikováno v: Chemical Geology. 534:119455
Preventing the inclusion of oxygen bearing compounds from the organic fraction of skeletal tissues is often considered key to obtaining faithful δ18O measurements of the mineral fraction, which are widely used across the archaeological, forensic and

Ahead of the curve?
Autor: Cheryl A. Makarewicz, Sarah Pederzani, Taylor Hermes
Vertical transhumance is a productive strategy used by pastoralists around the world. This type of mobility entails the movement of livestock to pastures located at different elevations, with moves calculated according to local, altitude-dependent av
