The inland town of Aalst is located on the banks of the River Dender, which is part of the Scheldt basin that drains the major part of Flanders, the northern part of Belgium. In an attempt to look for diachronic trends in fish consumption, ichthyological remains from 34 stratigraphic units, derived from seven different sites within the town, are compared, spanning the period from the twelfth to the end of the eighteenth century AD. It was hypothesised that for the medieval and postmedieval periods, the relative frequencies of the various taxa would reflect the historically established development of marine fish consumption and the gradual decline of freshwater fish exploitation due to overfishing and pollution of local freshwater habitats. While it was taken into account that factors such as social position and purchasing power will have influenced the spectrum of fish consumed, the results show that there is an unexpected large inter- and even intra-site variation, even within a restricted time period, patterns difficult to explain and hampering most interpretations. Considering diachronic comparison of the fish assemblages, this inevitably raises the question whether new insights will be easier to gain from wider generalisation or from going into greater interpretational detail.

The morphometric affinities of the 33,000 year old skeleton from Nazlet Khater, Upper Egypt are examined using multivariate statistical procedures. In the first part, principal components analysis is performed on a dataset of mandible dimensions of 220 fossils, sub-fossils and modern specimens, ranging in time from the Late Pleistocene to recent and restricted in space to the African continent and Southern Levant. In the second part, mean measurements for various prehistoric and modern African and Levantine populations are incorporated in the statistical analysis. Subsequently, differences between male and female means are examined for some of the modern and prehistoric populations. The results indicate a strong association between some of the sub-Saharan Middle Stone Age (MSA) specimens, and the Nazlet Khater mandible. Furthermore, the results suggest that variability between African populations during the Neolithic and Protohistoric periods was more pronounced than the range of variability observed among recent African and Levantine populations. Results also demonstrate a general reduction in the degree of sexual dimorphism during the Holocene. However, this pattern of reduction pattern varies by geographic location and is not uniform across the African continent.
