A revised terrace stratigraphy and chronology for the Little Ouse River as a framework for interpreting the late Lower and early Middle Palaeolithic of central East Anglia, UK

Abstract

The Breckland of central East Anglia has a Pleistocene geological sequence spanning c. 1 million years, providing a framework for assessing changes in human technology and behaviour within a single changing palaeolandscape. The geological record and its associated Palaeolithic archaeology divides into three chronological periods: the fluvial deposits of the River Bytham, which span c. 1 ma to 450 ka; the Hoxnian interglacial sites (c. 400 ka); and the fluvial terraces of the post-Anglian drainage network, which records the past c. 400,000 years. This paper focuses on the third of these periods, presenting results from new work on the fluvial sediments and Palaeolithic archaeology associated with the Little Ouse River. Fieldwork was conducted at four Palaeolithic sites; Barnham Heath, Redhill, Santon Downham, and Broomhill Pit. The new sedimentological and stratigraphic data are used in conjunction with existing borehole records to construct long profiles for the river terrace aggradations and establish a terrace stratigraphy for the Little Ouse. Correlation with the marine isotope record is supported by age estimates from electron spin resonance (ESR) dating of sand units within the terrace aggradations. The results provide an age-constrained lithostratigraphic framework for understanding the Lower and Middle Palaeolithic records of the Little Ouse. The results can be added to previous work on the Bytham and Hoxnian sites, enabling an assessment of human activity in the region from c. 800–200 ka.
