Neolithic fish remains from the freshwater shell midden Riņņukalns in northern Latvia

The Neolithic site Ri??ukalns in the Lake Burtnieks/River Salaca area in northern Latvia is the only freshwater shell midden in the eastern Baltic Sea area. An excavation carried out in 2011 revealed an intact stratigraphy with alternating layers of unburnt and burnt mussel shells and yielded various kinds of archaeological finds, among them several thousand fish remains. To gain an understanding of the fish species and specimens caught by the Neolithic settlers, and to discern any temporal development in the fish species composition, we analysed fish remains from different sections and layers. Results from both the archaeozoological and stable isotope data, give evidence for a change in the relevance of fish species during the period of use, and they also provide information for reconstructing the former river and lake hydrology in the vicinity of the midden. The Stone Age landscape seems to have been very similar to the present situation, so that the study area has been an extraordinarily stable ecosystem for more than 5000 years. Comparisons with the results of recent monitoring programmes, long-term changes since Medieval times, and written sources from the 18th century, show that the fish species community is almost unchanged since the Stone Age. This underlines the importance of the region in nature conservation.     

State‐of–the–art imaging in palaeopathology: the value of multislice computed tomography in visualizing doubtful cranial lesions

Non‐invasive imaging techniques are of great value in palaeopathology. Computed tomography (CT) is widely established to visualize changes in human remains that occurred both pre and post mortem. Since 1999 an advanced form of helical CT—so called Multislice‐CT (MSCT)—has become available for clinical purposes. We now present for the first time three historic cranial lesions of doubtful aetiology visualized by MSCT. Both original images and virtual reconstructions of the specimens are of high quality. In combination with peri‐lesional bone density measurements these images allow an improved assessment of aetiology. The cases presented are diagnosed by MSCT as being of intra vitam nature in two individuals and of post mortem character in one case. Time consuming post‐processing analysis and the still small number of scanners presently available may limit application of this new technique. Nevertheless, based on our preliminary results, we strongly recommend non‐invasive evaluation by MSCT to be used for non‐clinical purposes such as palaeopathological research.

Southern Iberia and the Mediterranean Trade-routes

The early Iron Age sites of southern Iberia (8th century to c. 600 BC) have produced large numbers of imports from the eastern Mediterranean, while only a very small number of southern Iberian objects found their way to other parts of the Mediterranean. Despite their scarcity these items can provide valuable information about the shift of trade routes in the Mediterranean at around 600 BC.
