The prehistoric dwellers in central Sudan, however, had “unusual” burial rites as evidenced by the prone and extended position of the skeletons found in Al Khiday 2.Read More Published on August 25, 2010 Beta Analytic, Inc.These remains include the fossils (preserved bones) of humans, food remains, the ruins of buildings, and human artifactsitems such as tools, pottery, and jewelry.From their studies, archaeologists attempt to reconstruct past ways of life.Archaeology is an important field of anthropology, which is the broad study of human culture and biology.

In addition, samples from the twopithouses (sites FB 5820 and FB 5843) were examined for possible protein residues.

In this study we present and assess a process to enhance archaeological residue AMS dating by focusing on contaminant confinement.

The sequence of methods applied consists of: 1) optical residue and use-wear analyses, 2) experimental designs addressing cleaning treatments to mitigate impact of contaminants, 3) preparation and extraction of residues from (mostly) previously dated stone artefacts, and 4) establishing the elemental characteristics of residues by using SEM/EDX as a final step to avoid sample contamination during analyses.

Clusters of towers have been erected on mountain slopes, and lone towers were built in river valleys. How they survived in a region prone to strong earthquakes is yet another unanswered question.
