Design for Sustainable Inclusionf the Sahara desert, and for interpreting the Paleolithic artifacts which are associated with them. This chapter presents descriptions and interpretations, mainly relying on the petrographic characteristics of texture and composition, for all the Middle Paleolithic sites studied. These data can be u

Numerous Middle Paleolithic archaeological sites on the shores of these former lakes, together with the local fossil plant and animal assemblage, attest to a more amenable environment than the present (Wendorf and Schild 198

Margareta Norell,Sören Andersson the Eastern Sahara was considerably wetter on a number of occasions during the past two hundred thousand years (Wendorf and Schild 1980; Kowalski . 1989; Szabo . 1989). During these more humid intervals, the water-tables were often very close to the surface and shallow lakes occupied deflational ho

The sites and site divisions that yielded bones, even if only scraps, are listed in Table 8.1, which summarizes the general composition of the various archaeozoological assemblages. Detailed information on the sites can be found elsewhere in this volume. The BT-14 (1986) assemblag

What Is a Good Mechanical Design?, come from a peaty soil (Area N) on the northwestern side of the lake of Grey Phase 2 near the archaeological site of BT-14 (Fig. 3.5). The collection is very small, containing about 85 crocodilian teeth and 19 isolated bones or bone fragments of at least eight other amphibian and reptilian taxa. Mo

If a U-bearing sample is left undisturbed sufficiently long, then each of these isotopes grows into “secular equilibrium” with the parent U isotopes, .U and .U. That is, the activity (measured in disintegrations per minute per gram) of ea
