Figure 1: Microliths diagnostic of assemblage types. Row 1. Star Carr-type microliths from Star Carr, N. Yorks. Row 2. Deepcar type microliths from Lackford Heath, Suffolk. Row 3. A basally modified assemblage. A Honey Hill-type assemblage from Two Mile Bottom, Norfolk (redrawn from Jacobi 1984). Row 4. Small scalene triangles from Seamer K, N. Yorks (redrawn from David 1998)
Figure 2: Overall form of the chronological models for the currency of different microlith types in Britain
Figure 3: Probability distributions of radiocarbon dates associated with long blades. Each distribution represents the relative probability that an event occurs at a particular time. For each of the dates two distributions have been plotted: one in outline, which is the result of simple radiocarbon calibration, and a solid one, based on the chronological model used. Distributions other than those relating to particular samples correspond to aspects of the model. For example, the distribution 'start long blades' is the estimated date when long blades were first used in Britain. Measurements followed by a '?' have been excluded from the model for reasons described in the text. The large square brackets down the left-hand side along with the OxCal keywords define the overall model exactly. (red: excluded from model; grey: TPQ possible old-wood effect or hard-water error; blue: TPQ/TAQ stratigraphic constraint; red: excluded from model)
