Pick the Right Pocket. Sub-sampling of Bone Sections to Investigate Diagenesis and DNA Preservation
Many archaeological bones display a heterogeneous degradation pattern. Highly degraded bones could contain pockets of well-preserved bone, harbouring good quality DNA. This dichotomy may explain why the relationships between global bone preservation parameters such as histological integrity, bone mineral crystallinity or collagen yield, and bulk DNA preservation/amplification success rate have been found to be at best, weak to moderate. In this p…
Non‐human primates avoid the detrimental effects of prenatal androgen exposure in mixed‐sex litters: Combined demographic, behavioral, and genetic analyses
Producing single versus multiple births has important life history trade-offs, including the potential benefits and risks of sharing a common in utero environment. Sex hormones can diffuse through amniotic fluid and fetal membranes, and females with male littermates risk exposure to high levels of fetal testosterone, which are shown to have masculinizing effects and negative fitness consequences in many mammals. Whereas most primates give birth t…
The Embarrassment of Riches: Rationalising Faunal Assemblages from Large Urban Sites
Museums and other curatorial bodies face the significant challenge of storing large volumes of material recovered from decades of archaeological excavation, amongst which are very large collections of animal bones. As stores fill up, there is pressure to reconsider curation policies, to the point of refusing further deposition and disposal of existing material. Faced with this situation, York Archaeological Trust looked to develop and implement a…
Walking on Eggshells: A Study of Egg Use in Anglo-Scandinavian York Based on Eggshell Identification Using ZooMS
Eggshell is a potentially common archaeological resource, but it tends to be ignored. The recent development of ZooMS (zooarchaeology by mass spectrometry) as a rapid and robust system for taxonomic identification of preserved eggshell fragments has facilitated new insights into patterns of egg use in the past. This paper presents a case study of egg use at two sites in Anglo-Scandinavian York (Hungate and Coppergate). The results described below…
Great ape genetic diversity and population history
High-coverage sequencing of 79 (wild and captive) individuals representing all six non-human great ape species has identified over 88 million single nucleotide polymorphisms providing insight into ape genetic variation and evolutionary history and enabling comparison with human genetic diversity. In an effort to provide insights into great ape genetic variation, the authors sequence 79 wild- and captive-born individuals from across all six great …
Excavations at Stackpole Warren, Dyfed
Excavations of sites spanning the Beaker to early Roman periods at Stackpole Warren, Dyfed, are described. The sites are in an area of blown sand which enhanced their preservation and led to the separation of several horizons. The earliest is a buried soil beneath the blown sand which contained Mesolithic to Bronze Age artefacts. At site A, there was a roundhouse associated with Early Bronze Age pottery and dated to 1620±70 and 1400±70 BC uncal.,…
