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.

Direct Evidence of the Geographic Origins of Horse in the Yaoheyuan Site From Ningxia, China

Archaeometry, EarlyView.
ABSTRACT In this study, It is explores the geographic origin of horses by analyzing the strontium isotope ratio of horses from the Yaoheyuan site, an important site in the northwest region of China during the Western Zhou Dynasty. The results show that most of the horses at the Yaoheyuan site were domesticated locally, while a small number came from ...

Proteomic Sex Estimation From Embedded Tooth Enamel

Archaeometry, EarlyView.
ABSTRACT Teeth hold insights into childhood diet, health and demography—including chromosomal sex. Proteomic analysis can detect peptide biomarkers from amelogenin genes encoded on X and Y chromosomes, allowing sex estimation. Embedding resins, necessary for thin sectioning teeth, can damage analytical systems, preventing proteomic analysis. We present

The Early Upper Palaeolithic open‐air site of Friedrichsdorf‐Seulberg, Germany, in the context of the northern central European Aurignacian

Boreas, EarlyView.
Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...

Ecological variability of Hippopotamus antiquus from the late Early–Middle Pleistocene of Megalopolis Basin (Greece): Evidence for dynamic habitats in a glacial microrefugium

Boreas, EarlyView.
This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

Understanding Rheumatoid Arthritis‐Oral Health Perceptions Around Diagnosis and the Early Disease Course: A Phenomenological Approach

Community Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives To explore how Dutch adults with rheumatoid arthritis (RA) perceive their oral health around the diagnostic process and the early disease course. The primary objective was to describe these perceptions in depth, and a secondary objective was to identify areas for future patient‐centred research.
