| Abstract: | The lowest stratigraphic unit of Theopetra cave (Greece) contains a Middle Palaeolithic sequence radiocarbon dated to between 46 and 35 ka BP; at the limit of this dating method. The upper part of this sequence has yielded late Middle Palaeolithic lithic assemblages containing several early Upper Palaeolithic artifacts. To get more precise dates for the human occupation of the cave, burnt flint specimens from these Middle Palaeolithic layers were dated by thermoluminescence. The dates obtained are coherent and indicate that the first human occupation of the cave took place at the end of isotopic stage 6 or more probably at the beginning of stage 5, much earlier than previously proposed. In the light of this new evidence, it is reasonable to assume that: (a) Theopetra contains the oldest dated Middle Palaeolithic deposits of Greece and (b) that the assemblages first interpreted as “Transitional Middle/Upper Palaeolithic” industries may be the result of post-depositional mixing of cultural material. |
