Central Europe during the Last Glacial Maximum (LGM) was dominated by polar desert and steppe-tundra biomes. Despite this, a human presence during this time period is evident at several locations across the region, including in Switzerland, less than 50 km from the Alpine ice sheet margin. It has been hypothesised that such human activity may have been restricted to brief periods of climatic warming within the LGM, but chronological information from many of these sites are currently too poorly r...

Plant-derived secondary metabolites consumed in the diet, especially polyphenolic compounds, are known to have a range of positive health effects. They are present in circulation after ingestion and absorption and can be sequestered into cells within particular organs, but have rarely been investigated systematically in osteological tissues. However, a small number of polyphenols and similar molecules are known to bind to bone. For example alizarin, a plant derived anthraquinone and tetracycline...

Abstract Collagen isolated from archaeological bone is a common material for radiocarbon dating, stable isotope analysis, and zooarchaeology by mass spectrometry (ZooMS). However, not all bones contain extant collagen, leading to unnecessary destruction of unproductive bones and wasted laboratory time and resources. An aim of this research is to study bone diagenesis, particularly collagen destruction, in an effort to develop a minimally destructive method for identifying bones with high collage...

Abstract Results from AMS dating applied to insect chitin from a variety of contexts and different preservation conditions and retrieval methods are presented. Secure contexts, which include other dated organic material from different geographic locations ranging from Egypt to Greenland and different chronological periods, from Lateglacial to Medieval, have been used. In addition, insect species with different dietary requirements have been selected for dating purposes in order to provide an und...

Remains of insects are often found in an archaeological context, and because insects are sometimes temperature sensitive, their presence in archaeological and environmental contexts gives them climatic significance. The use of accelerator mass spectrometry (AMS) to date small samples has allowed for the direct analysis of insect remains, and these studies have given a deeper understanding of Quaternary climate change and its effects on human activity during this time. In addition, the presence o...

A versatile method for grafting reactive polymer onto macroporous polymer monoliths has been developed, and this method used to prepare a monolith containing primary amines. Reactive polymer was grafted onto residual olefins within the crosslinked monoliths using free-radical polymerization, and without requiring any pre-grafting activation. Capacities of the grafted monoliths were easily controlled by altering the composition of the grafting solution. Grafting N-vinylacetamide, followed by amid...

Coastal archaeological sites that lack organic remains for radiocarbon dating are often abundant sources of molluscan shells. As a substitute for materials such as bone and charcoal, shells can be analyzed with 14C dating to determine a site's age. Despite their being convenient, non-mobile archaeological artifacts, molluscan shells are plagued by several issues, including carbonate remodeling, in which aragonite in shells is converted to calcite as predicted by thermodynamics. We present here a...

Isolation of bone collagen for radiocarbon dating is a labor-intensive and time-consuming process that sometimes results in unacceptably low protein recovery. In preliminary studies reported here, micro-computed tomography (microCT), a nondestructive technique that uses X-rays to produce high-resolution three-dimensional images of mineralized materials such as bone, offers promise as a suitable prescreening option for bones of questionable preservation. We have found that the bone volume fractio...
