Lacustrine Paleoenvironments of the Area of Bir Tarfawi-Bir Sahara East Reconstructed from Fossil Os 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

Szeroczyńska processed 18 samples from the deep-water section of the Pool in Tr. 3/86, following the methods described by Siemińska (1964). The samples yielded very few diatoms, so an additional 22 sediment samples, taken from the near-shore section of the northern profile of

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

Remains of Small Vertebrates from Bir Tarfawi and Their Paleoecological Significance 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

Uranium-Series Dating of Carbonates from Bir Tarfawi and Bir Sahara Eastlf-lives are comparable to the time-scale of the Pleistocene. 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

The preliminary TL results were good but a lack of communication between laboratory and excavator led to the TL measurements being discontinued. In 1987, there was a revival of interest in the project, which has now been completed (Huxtable 1990)

These stored charges gradually build up in a crystal as a result of bombardment by natural radioactivity. The charge content at any time is therefore a measure of the acquired radiation d
