Isotopic composition and identification of the origins of individuals buried in a Neolithic collective grave at Bronocice (southern Poland).

The oxygen present in a human organism comes from numerous sources, but the major factor that causes variation in the isotopic composition of this element in a tissue is available drinking water. The isotopic ratio of oxygen in an organism's tissue, including that found in bones and teeth, reflects the isotopic oxygen composition typical for the area where a given individual developed and lived. Of particular interest with regard to this issue were a series of skeletons from the multiple grave discovered at the Funnel Beaker-Baden settlement at Bronocice (southern Poland). The question therefore arose whether the specimens buried in this grave were part of the local community. The oxygen isotope level was established using apatite isolated from bones or teeth. A femur and root dentine samples taken from permanent teeth were subjected to oxygen isotope analysis. The oxygen isotope level of the site was established on the basis of local water precipitation and measurements taken from the oxygen isotope concentration in apatite samples isolated from the bones of animals co-occurring with the studied human group. It has been found that the oxygen isotope levels in the bones and dentine of almost all the analysed specimens from the excavated site at Bronocice were within the established range for the area's environment, providing evidence for their local origin. Thus, it can be assumed that the analysed group inhabiting the macrosettlement at Bronocice during the Funnel Beaker phase of the Baden culture was most probably of local origin.

Hyperostosis frontalis interna, a genetic disease?: Two medieval cases from Southern Poland.

Two cases of thickening of the internal tables of the frontal bones (hyperostosis frontalis interna, (HFI)) have been examined. These were two female skeletons from the 16th century Dominican Church in Raciborz (Southwest Poland). The similarity of their morphological and metrical traits indicates that they could be related, and suggests that HFI is likely to have a genetic base. These two skeletons are the subject of an analysis which may possibly throw some new light on the controversial and continually disputed nature of this illness.

Trace element analysis of Bronze Age skeletal and crematory graves from southern Poland for diet reconstruction.

The basic aim of the present study was to determine the diet of human populations dating from the Bronze Age and the time of Roman influence. The osseous material under examination came from skeletal and crematory burials of the Lusatian and Przeworks Cultures, found in a cemetery at Opatów, Klobuck District, Silesian Province. Three elements: strontium, zinc and calcium were chosen as basic diet determinants. The three elements and the proportions between them are the most frequently used factors that permit a description of the relative proportion of animal and plant protein in a diet. It was assumed that the differentiation of burial ritual was paired with a diverse mode and quality of nourishment. Interdisciplinary osteological analyses, based on physicochemical studies of the odontologic material in the context of archaeological data (culture affiliation, type of burial, grave furnishings), permit a complex analysis of the issues connected with the biology of human groups, their demographic structure or, eventually, paleostratigraphy of primeval communities. It has been found that the type of burial and the richness of grave furnishings are most closely connected with the ultimate differentiation of Zn and Ca concentrations and the value of the Sr/Zn ratio. Because the richly furnished graves are at the same time mostly skeletal burials, it cannot be unequivocally stated which of the above-mentioned factors is of paramount importance. It has also been demonstrated that representatives of the Przeworsk Culture, chronologically younger than the Lusatian one that inhabited the same geographic region, show a lower Zn concentration and a higher Sr/Zn ratio.

Cribra orbitalia and trace element content in human teeth from Neolithic and Early Bronze Age graves in southern Poland.

Determination of element levels in bones and teeth can complement knowledge of the diagnostics and etiology of various diseases in prehistoric populations. Calcium (Ca), cadmium (Cd), copper (Cu), iron (Fe), and lead (Pb) content were analyzed in teeth from human skeletons dated to 3,000-1,400 BC from Malopolska Upland loess. Levels of iron and calcium were determined using atomic absorption spectroscopy (AAS), and lead, cadmium, and copper levels were measured using anodic stripping voltametry (ASV). Molar teeth from specimens with cribra orbitalia were selected for analyses, and teeth from specimens with no pathological changes were used as a control. No significant correlations between the content of particular elements and the tooth class, specimen age, or depth of burial pit were observed. The Fe content in specimens with cribra orbitalia is not the best measure for this disease's etiology. Thus, interelement correlations and proportions might give a better picture of the biological condition of the specimen and of the investigated groups.
