“…All stable isotope results derived were summarized in Ccol vs. δ 1 5 Ncol from Roughground Farm. Ccol vs. δ 1 3 correspond to previous research, [15][16][17] where the larger isotopic spacing was reported in ruminants in comparison with the non-methanogenic animals.…”

“…1 On the other hand, diet-to-apatite carbonate carbon isotopic enrichment was reported as being 9.4‰, although that of ruminants was reported as being around 12-14‰, whereas that of non-methanogenic animals is about 9‰. [15][16][17] Therefore, additional isotopic information can be obtained from bone collagen and apatite carbonate together, compared to the results produced by collagen itself, because the δ 13 C value of bone carbonate neither overestimates-nor underestimates the proportions of carbon atoms from dietary components. 3 For example, the isotopic analysis of collagen may over-represent a δ 13 C enriched marine diet, and may also under-represent δ 13 C enriched plant foods such as maize.…”

This paper presents a stable isotope chemistry of bone collagen and carbonate. Bone carbonate has the potential to provide additional isotopic information. However, it remains controversial as to whether archaeological bone carbonate retains its original biogenic signature. I used a novel application of bone density fractionation and checked the integrity of δ 13 C apa values using radiocarbon dating. Diagenesis in archaeological bone carbonate still remains to be resolved in extracting biogenic information. The combined use of bone density fractionation and differential dissolution method shows a large shift in the δ 13 C apa values. Although δ 13 C apa values are improved in lighter density fractions, a large percentage of contamination in bone carbonate was reported via 14C dating compared to that noted with bone collagen.

“…The δ 13 C apa-col values for herbivores fall within the previously reported range (7‰; however, there are δ 13 C apacol differences between large (cattle and red deer) and small herbivores (ovicaprines and swine). Cattle exhibit enriched δ 13 C apa-col values, probably due to methanogenesis (Hedges, 2003). According to Ambrose and Krigbaum (2003), ruminant herbivores have symbiotic digestive microbes that produce large amounts of methane.…”

This study presents for the first time the diet of a Late Antiquity population in southern Portugal (Civitas of Pax Julia), from the Roman villa of Monte da Cegonha (predominantly 7th century CE). Stable isotope analysis (δ 13 C, δ 15 N, δ 18 O, 87 Sr/ 86 Sr) of human and faunal bone collagen and apatite was conducted in order to understand the influence of Roman subsistence strategies on the way of life of rural inhabitants of the area of Pax Julia and to explore their diet (types of ingested plants, amount of animal resources, terrestrial versus marine resources). X-ray diffraction (XRD) and Fourier transform infra-red spectroscopy (FTIR) analyses were used to determine the degree of bone diagenesis and assess the reliability of the bone stable isotopic composition for palaeodietary reconstruction. Anthropological analysis revealed a cariogenic diet, rich in starchy food and carbohydrates, in at least in two individuals based on the frequency of dental caries. Collagen and apatite carbon isotopic analysis suggested that C 3 plants were the basis of the population's diet, complemented with some terrestrial meat and its byproducts as reflected by the observed bone collagen nitrogen isotopic composition. Moreover, whilst the fairly low apatite-collagen spacing recorded in some skeletons (at around 4‰) may have been due to freshwater organisms intake, the relatively low nitrogen values observed indicate that this consumption did not occur very often, unless in the form of fresh fish of low trophic level or fish sauces. There were no significant differences in isotopic values depending on gender or burial type. Strontium and oxygen isotopic composition of bone apatite revealed a sedentary community, with the exception of a male individual who probably did not spend his childhood in Monte da Cegonha.

IntroductionIn order to gain an understanding of the economic basis of prehistoric communities, the identification of dairying is essential, particularly in northwest Europe, where a high degree of lactose tolerance suggests that fresh milk has long been a significant dietary component. Currently, prehistoric dairying is investigated using a variety of techniques.The two techniques that have been most widely applied are the examination of faunal remains and compound-specific stable isotope analysis of lipids in pottery residues.Examination of faunal remains to determine age-at-death slaughter patterns (mortality profiles) and female to male ratios (Higham 1968;Payne 1973) allows the economic role of a particular species (e.g. for meat, wool, milk or traction) to be inferred (e.g.Legge 1981), whilst lipid analysis is effective at identifying the presence of milk products in the archaeological record (e.g. Dudd and Evershed 1998;Copley et al. 2005a). Recent developments in the detection of archaeological proteins have allowed the identification of milk proteins to species in both organic residues and human dental calculus (e.g. Hong et al. 2012;Buckley et al. 2013; Warinner et al. 2014).An additional approach to identify cattle (Bos taurus) dairying in prehistoric communities is explored in this paper: a possible relationship between calving seasonality, i.e. the distribution of births throughout the year, and economic focus. For economies focussed on the year-round production of fresh milk as a staple food product, it has been postulated that multiple-season calving would have been necessary (Towers et al. 2011;Balasse et al. 2012a;Gron et al. 2015). In contrast, a strategy of singleseason calving, probably in spring, may have been favoured for meat-based economies or economies focussed on storable milk products. Increasingly, birth seasonality of domestic herbivores has been investigated using intra-tooth isotope ratio analysis of molar enamel (e.g. Balasse et al. 2003;Balasse and Tresset 2007;Blaise and Balasse 2011;Towers et al. 2011;Balasse et al. 2012a;Balasse et al. 2012b;Tornero et al. 2013;Towers et al. 2014;Buchan et al. 2015;Gron et al. 2015).Each of the aforementioned techniques to identify p...
