At the time of excavation Savory assigned the plano-convex flint knives to the early Middle Bronze Age. Under the current chronology they are assigned to the Early Bronze Age Period III.

The horizon elevations given have been determined from Ordnance Survey 1:25,000 scale maps (Sheets ST 48/58 and ST 49/59) and the values are therefore subject to error. It is thought unlikely, however, that the error in elevation exceeds ± 0°.1, with a resulting declination error of around the same magnitude. The horizon is assumed to be free of vegetation cover and the observer's eye height has been taken as 1.55m. All declinations given have been calculated making the necessary allowances for refraction.
