Contemporaneity of Clactonian and Acheulian flint industries at Barnham, Suffolk, Antiquity 68: 585-9.
On the Clactonian industry at Swanscombe, Proceedings of the Prehistoric Society of East Anglia 6:79-116.
This industry in the past has been termed Clactonian (Paterson 1937; Wymer 1985).
At Barnham an industry which has traditionally been interpreted as Clactonian is also seen to be contemporary with biface manufacture.
There are large Clactonian
notches on all four margins.
After a brief introduction to the Clactonian problem, the first chapters provide an excellent review of which hominin species might have been present in Britain during the Lower Palaeolithic, the sequence and nature of climatic change as evidenced by the scale of the Marine Isotope Stages, and the models that have been developed by geographers to account for the specific form of the build-up of river terraces in the major river basins in Southern England and the Midlands.
The second part of the book stands back and explores our understanding of this period and of the Clactonian problem as a form of intellectual history, setting out when particular terms, forms of classification and understandings of change came into being, and the effects that they have exerted on later scholars.
Spatial analysis shows that the low technical investment inherent in the Clactonian
method could signify that it meets only temporary needs that develop with the movement of the flint block on the site.
Archaeologically, Barnham is most famous for the cultural succession first defined by Paterson (1937) and modified by Wymer (1985): abraded and fresh Clactonian assemblages from within and atop the cobble band, with a fresh Acheulean assemblage in the immediately overlying brickearth.
Indeed, chronologically there is still no concrete evidence for an Acheulean in Hoxnian Britain before pollen subzone HoIIc, while Clactonian occurrences appear to be restricted to HoIIb and earlier (cf.

Number of operational surfaces contrasts Levallois, Clactonian
and Discoid structures, which include two surfaces, to the triface structure which includes three.
