This thesis examines technological behaviour during the early British Middle Palaeolithic (Late OIS 9-7), as reflected by lithic artefacts. The British data-set, whilst containing few high-resolution sites providing information relevant to ethnographic-scale behavioural reconstruction, actually forms a valuable corpus of well-contextualised locales within a tightly constrained chronostratigraphic framework. Lithic artefacts from these sites can be used to address broader questions concerning the emergence and nature of particular "Middle Palaeolithic" behaviours; specifically, the emergence of, and variability within, Levallois technology in Britain, and increasing complexity in the organisation of technology in the landscape.
