Dates, Diet, and Dismemberment
We present radiocarbon dates, stable isotope data, and osteological analysis of the remains of a minimum of 17 individuals deposited in the western part of the burial chamber at Coldrum, Kent. This is one of the Medway group of megalithic monuments – sites with shared architectural motifs and no very close parallels elsewhere in Britain – whose location has been seen as important in terms of the origins of Neolithic material culture and practices…
Compound-Specific Radiocarbon Dating of Essential and Non-Essential Amino Acids
When humans consume foods from different radiocarbon reservoirs offset in age to the atmosphere, inaccuracies in the 14 C date of bone collagen can occur. Mesolithic human skeletons from the Iron Gates section of the Lower Danube Valley have yielded reservoir offsets of up to ∼500 yr. This has been demonstrated through direct dating of bulk collagen from human bones and the remains of ungulate bone projectile points that were found embedded in th…
Evaluating marine diets through radiocarbon dating and stable isotope analysis of victims of the AD79 eruption of vesuvius
The stable carbon (δ 13 C) and nitrogen (δ 15 N) isotope values of bone collagen are frequently used in paleodietary studies to assess the marine contribution to an individual's diet. Surprisingly, the relationship between stable isotope these values characteristics and the percentage of marine foods in diet has never been effectively demonstrated. To clarify this relationship, the stable isotope values and radiocarbon dates of nine humans and on…
Roots of diversity in a Linearbandkeramik community
The early Neolithic in northern Central Europe ought to be the theatre in which incoming farmers meet local hunter-gatherers, with greater or lesser impact. By way of contrast, the authors use isotope analysis in a cemetery beside the Danube to describe a peaceful, well-integrated community with a common diet and largely indigenous inhabitants. Men and women may have had different mobility strategies, but the isotopes did not signal special origi…

Improvements to the Pretreatment of Bone at Oxford
Bone is one of the most widely used materials for dating archaeological activity. It is also relatively difficult to pretreat effectively and new methods are an area of active research. The purpose of the chemical pretreatment of bone is to remove contaminants present from burial and to do so in a way which does not add any additional laboratory contaminant. To some extent, these two aims must be balanced since, on the whole, the more complex the…
Differentiating Bone Osteonal Turnover Rates By Density Fractionation; Validation Using the Bomb 14 C Atmospheric Pulse
The density (BSG) of bone increases, at the osteon scale, during lifetime aging within the bone. In addition, post-mortem diagenetic change due to microbial attack produces denser bioapatite. Thus, fractionation of finely powdered bone on the basis of density should not only enable younger and older populations of osteons to be separated but also make it possible to separate out a less diagenetically altered component. We show that the density fr…
New evidence of Lateglacial cereal cultivation at Abu Hureyra on the Euphrates
Hitherto, the earliest archaeological finds of domestic cereals in southwestern Asia have involved wheats and barleys dating from the beginning of the Holocene, 11–12000 calendar years ago. New evidence from the site of Abu Hureyra suggests that systematic cultivation of cereals in fact started well before the end of the Pleistocene by at least 13000 years ago, and that rye was among the first crops. The evidence also indicates that hunter-gather…

Archaeology and genetics
We review some of our recent work on the analysis of DNA extracted from skeletal remains up to four thousand years old, which is made possible by the exquisite sensitivity of the polymerase chain reaction. To do this, we consider in some detail our approach to a particular archaeological problem, the question of the scale and nature of the settlements which took place in post‐Roman Britain. This involves the analysis of the mitochondrial DNA cont…
