Barnham 2021 Gets Underway

After a year without fieldwork, the PAB team is excited to be back out in the field at Barnham. Excavations since 2013 at this important Lower Palaeolithic site have revealed a lot of new information and transformed our understanding of the site and its wider context and significance. The stratigraphy and the relationship of the handaxe and core-and-flake assemblages at Barnham have both be revised, these findings were published in 2016.  As well as significantly increasing the number of lithic artefacts from the site, a large-scale sieving programme of the fine-grained sediments in the centre of the basin has yielded much new environmental information including several additions to the faunal list. The palaeobotanical information from the site has also been enhanced through the location of an organic unit which has enabled new pollen and plant macrofossil work. The excavations have also yielded a large quantity of burnt flint fragments, most are natural fragments, but a few are lithic artefacts. To explore this intriguing evidence of burning at Barnham, analysis of sediment found associated with the burned flint has been carried out using Fourier-Transform Infrared Spectroscopy (FTIR) techniques to detect a heating signal. Careful excavation has also identified several possible charcoal fragments, which await further detailed study.

After two years of collapse and vegetation regrowth, the site is going to need quite a lot of work to recover the excavation and with a scaled-down research team on site everyone will be working hard to make up for lost time and get the research project back on track. Priorities for this year are to complete the sampling and processing of the sediments in Area III. Sieving is done on site, so the excavated sediment is first dried, then soaked overnight with a dispersant before being washed through a fine-mesh sieve and the retained residues are then taken back to London for sorting and identification. We also hope to continue the search for artefacts. This will allow the archaeological evidence to be more closely tied into the geological, environmental record at Barnham.
