Spondylolysis in Inuit skeletons from Arctic Canada

Inuit skeletons from archaeological sites in Arctic Canada were examined for the presence of spondylolysis. The largest series represent the Thule culture and historic Inuit from northwest Hudson Bay and Labrador, and Sadlermiut from Southampton Island. The condition was found in 90 individuals, with a total of 120 affected vertebrae producing 198 hemi‐arch defect sites. As in other studies, L5 is affected most frequently, followed by L4 and L3, but examples of L1, L2, L6, and S1 involvement are represented. Incomplete separations account for 20% (40) of the 198 defects, and 5% (10) occur at sites other than interarticularis. Affected males outnumber females at a ratio of 2.4 to 1. The condition was found to increase in frequency from adolescence to young adulthood, and then decrease to middle adulthood and decrease again to old adulthood, but the drop in frequency with age in the adult categories is significant only at the .20 level. Where comparisons could be made, the data obtained from the Canadian Inuit closely resemble those obtained from Alaskan Eskimos and Aleuts, especially their closest linguistic relatives, Inupiat speakers in northern Alaska.

The role of labrid fish in prehistoric economics in New Zealand

Labrids are one of the most common types of fish to occur in inshore rocky marine habitats in New Zealand. There are major discontinuities in their relative abundance in archaeological sites from different regions of New Zealand, and these are difficult to reconcile with known distributional patterns. A number of possible explanations are examined such as changes in fishing technology and various ecological factors. It is concluded that the reasons for these observed fluctuations may vary considerably from one case to another, but where large numbers were caught by prehistoric people who had access to alternative fish resources, unreliability of some major aspect of the economy may be inferred. A combination of poor sea conditions and marginal horticulture is likely to increase the importance of labrid fish.     

Isotopically distinct modern carbonates in abandoned livestock corrals in northern Kenya

We report δ¹⁸O and δ¹³C data from modern carbonate in soils and dung samples from 3 recently abandoned livestock corrals in northern Kenya. Calcium carbonate content is higher within ∼5 cm depth that contains a mixture of dung and surface soils of corrals than in soils below 5 cm depth. We radiocarbon dated carbonates from 0.5 to 40 cm depths in two corrals and one control site. Surface carbonates (0.5 cm) from the two corrals were formed from modern carbon (>1955) when the corrals were active, while all other carbon is >16,000 years (BP) old. Shallow carbonate is also enriched in ¹⁸O (δ¹⁸O up to 3.0‰) and depleted in ¹³C (δ¹³C up to −12.0‰) with respect to carbonate at deeper levels and at two control sites. The δ¹⁸O and δ¹³C of soil carbonates (δ¹⁸O_SC and δ¹³C_SC respectively) in corrals are inversely correlated for depths up to about 15 cm where organic carbon is greater than 0.5%. Below that depth, there is a positive correlation between δ¹⁸O_SC and δ¹³C_SC values, similar to that observed in a control site.     

A palaeodietary investigation of carbon (C/C) and nitrogen (N/N) in human and faunal bones from the Copper Age cemeteries of Varna I and Durankulak,Bulgaria

Stable isotope analyses have been applied to human and faunal bone collagen from the Varna I and Durankulak cemeteries to explore palaeodietary adaptations in the Neolithic and Eneolithic (Copper Age). The results suggest both populations primarily utilised terrestrial, C₃-based diets, despite their proximity to the Black Sea. The wider δ¹⁵N range of the Durankulak humans likely indicates the differential utilisation of terrestrial meat sources, which is probably related to the degree to which primary and/or secondary ovicaprid products were consumed, particularly since ovicaprid δ¹⁵N values differ from other herbivores. The isotopic distribution of Varna I reflects a linear relationship between δ¹⁵N and δ¹³C, suggesting that a minority of individuals enriched in both isotopic parameters supplemented their diets with marine resources. These burials include the well known ‘chieftain’ (burial 43) and show notable material wealth by way of grave goods. At the population level, however, there is no significant correlation between stable isotope values and material wealth at Varna I, a fact with implications for theories regarding emergent social/economic hierarchies in Balkan prehistory. Five burials at Durankulak were found to have relatively enriched δ¹³C and δ¹⁵N values with respect to the rest of the population. These burials reflect a prominently marine-based or mixed terrestrial C₃-based diet that included C₄ inputs, possibly from millet, for which the limitations of stable isotope analysis on bulk collagen are not able to differentiate. AMS dating has shown that these burials belong to a much later period.
