The "trophic level enrichment" between diet and body results in an overall increase in nitrogen isotopic values as the food chain is ascended. Quantifying the diet-body Δ(15) N spacing has proved difficult, particularly for humans. The value is usually assumed to be +3-5‰ in the archaeological literature. We report here the first (to our knowledge) data from humans on isotopically known diets, ...

Abstract Stable carbon and nitrogen isotopic ratios (δ 13 C, δ 15 N) in bone collagen of archaeological skeletal finds are indicators the protein sources individuals’ basic diet. Isotopic sourcing allows us to quantify biomass contribution major dietary components differentiate between source various animal species (domesticates, game). We re-evaluated previously published signatures skeletons ...

This study compares trends in dietary composition in two large cemetery populations from the site of Kulubnarti (AD 550–800) in Sudanese Nubia. Bone collagen and bone apatite carbonate were analysed to characterise stable carbon, nitrogen and oxygen isotopes. Previous research on these cemeteries has suggestedmarked differences in nutritional status and health between the populations. Contrary ...

We report here on the first measurements of N34S in small (6 10 mg) samples of ancient bone collagen extracted from humans (n = 23) and animals (n = 4) from various European archaeological sites. Measurement of N34S values complement collagen N13C and N15N measurements and can provide corroboratory palaeodietary insights or new locality information. In areas where there are clear N34S differenc...

The Present study carried out on the bone samples collected from Roopkund Lake in Chamoli Garhwal, Uttarakhand, which is located 5029 meters from main sea level in between Nanda Ghunghti and Trishuli peak. This historical site belongs to the 9th century A.D.  All the samples selected for the study were dried in room temperature, as well as in hot air ovens at 32 degree Celsius. The Cleaning, pr...
