Mc Burney's Layer XXV, associated with Upper Palaeolithic Dabban blade industries, has a clear stratigraphic relationship with Campanian Ignimbrite tephra.
Microlithic Oranian technologies developed following the climax of the Last Glacial Maximum and the more microlithic Capsian in the Younger Dryas.
Despite problems of sediment transport and reworking, using a Bayesian statistical model the new dating program establishes a robust framework for the five major lithostratigraphic units identified in the stratigraphic succession, and for the major cultural units.
The age of two anatomically modern human mandibles found by Mc Burney in Layer XXXIII near the base of his Levalloiso-Mousterian phase can now be estimated to between 73 and 65 ka (thousands of years ago) at the 95.4% confidence level, within Marine Isotope Stage (MIS) 4.
In Libya, most of the socialising is around weddings.
In a culture where romantic relationships outside wedlock are heavily frowned upon and where it is taboo to live with someone other than your husband, marriage is the only acceptable route to a relationship and to leave your father’s house to create one of your own.
Comparison with unfired parent material indicates that anthropogenic firing of hearth rocks was sufficient to empty the OSL source traps.
The OSL ages for hearth rocks are internally consistent and suggest use around 8 ka.
Neolithic pottery and perhaps domestic livestock were used in the cave from the mid Holocene but there is no certain evidence for plant cultivation until the Graeco-Roman period.
Circular concentrations of burned stone fragments are widespread in the Sahara, and are generally interpreted as ancient hearths.
