The relevance of TL signal measured in the laboratory to the archaeological event to be dated is discussed, together in general terms with the types of material that are datable. The stability and saturation of the signal and the bearing of these factors on the upper age limit of the method are also considered. The necessity of in situ measurement of radiation levels on any site to be dated is emphasised. The development, limitations and some examples of the application of TL dating to three materials is then discussed in more detail. These materials are burnt flint, stalagmitic calcite and sediment and are those most commonly used for TL dating to the Palaeolithic.

Recent progress in ESR dating of tooth enamel opens the possibility to evaluate age assignments for many sites. The dating range of this new technique is between a few thousand to at least 1-2 million years, which covers approximately the entire Pleistocene epoch. However, this method, which is still under research, contains some problems, especially the still unknown process of uranium accumulation in teeth. Nevertheless, comparative studies with other dating methods, e.g., at Bilzingsleben gave very promising results.

The technique is compared to TL (Thermoluminescence) dating of sediments, to which it is closely related. The particular advantage of using zircon grains is indicated as well as the likely age for the techniques in general, and expected archaeological applications.

Many of the ages obtained relate to Middle Palaeolithic industries or the hominids we assume made them. While undoubtedly many of these datings will come to be revised in future as our understanding of the technical problems involved in these dating techniques evolve, nonetheless enough dates now exist for us to re-examine the chronological pattern of cultural change they suggest. An attempt will be made to present an overview of the corpus of dates already published and their implications for the thorny, if ancient, question of the meaning of the patterned technological variation found in Middle Palaeolithic assemblages, particularly from deeply-stratified sites.

For the Neanderthal child and adult remains from Fate cave (Finale Ligure, Italy), we obtained a U-Th age of 83 + 35/-24 Kiloyears (ky) and a U-Pa age of 76 +18/-13 ky. These ages are in good agreement with the ESR ages of the two lower stalagmitic layers of this cave : 78 ± 9 ky and 78 ± 13 ky. 2. Animal bones from Tournal cave, Genay Breccia site (France) and Arbreda cave (Spain) are also dated. U-Th and U-Pa ages of these sites are respectively, 33 ± 8 ky and 33 ± 4 ky for Tournal cave, 82 +20/-16 ky and 75 ± 6 ky for Genay Breccia site, 85 +38/-28 ky and 83 +11/-9 ky for Arbreda cave.
