Figures 18a and 18b: Entries of possibly Iron Age and possibly Roman date: comparison between the former (18a) and latter (18b) show some areas complementarity, with Romano-British settlements perhaps developing alongside the communication network and the rest of the countryside remaining unchanged. Elsewhere, new Roman sites concentrated in the Howardian Hills and the shift in focus from the Wolds to the Vale of York may be genuine changes dating to the latter period.
