The model for Deepcar-type assemblages is shown in Figure 5. Dates are available from nine sites, although only Oakhanger V/VII has more than four measurements. Five of these, however, contained a component of unidentified or pine charcoal, and so may have an old wood offset. With this caveat, occupation at Oakhanger is modelled as a continuous period of occupation.
This model suggests that Deepcar type assemblages first appeared in 9460–8705 cal BC (95% probability; start Deepcar-type; Figure 5), probably in 9090–8775 cal BC (68% probability). Deepcar-type assemblages disappeared in 8200–7240 cal BC (95% probability; end Deepcar-type; Figure 5), probably in 8075–7620 cal BC (68% probability).
