ABSTRACT
This chapter concerns the period of time spanning late MIS 12 which is the end of the Anglian glaciation, the interglacial that followed MIS 11 often called the Swanscombe Interglacial, and the return to arctic conditions at the beginning of MIS 10. The flatter ovate and cordiform morphologies are present in the Boyn Hill/Orsett Heath Middle Thames, but in much smaller numbers the pointed and well-shaped handaxes with straight sides predominate. Bridgland's river terrace model was primarily developed on sites from the Lower Thames Valley which explains why it is particularly suited to the sites discussed. On the face of it, the Severn and Avon system should potentially be another Lower Thames Valley; long rivers providing access for hominins ranging inland, and a clear flight of terraces up the sides of the valleys. The Solent continued to flow in its valley as it did in pre-Anglian times, and remained the main drainage artery for the Hampshire basin.
