Coastal curios? A new paper explores recent finds on the beach at Happisburgh 

A new paper by Dr Rachel Bynoe, with PAB researchers and three collectors, has recently been published in Journal of Quaternary Science (the paper is available under open access here).

The paper reports on the large collection of ex situ flint artefacts and mammalian fossils found on the beach and it demonstrates the way in which the time spent on the beach collecting Palaeolithic artefacts and Pleistocene fossils can contribute to research knowledge and understanding. The paper explores the material collected by three of the co-authors, Tim Grimmer, Jo Leonard and Darren Nicholas, along a 5km stretch of the Norfolk coast from Happisburgh to Eccles North Gap between 2013 and 2017. A total of 741 artefacts and 157 mammal fossils were included in this study.

The collections were made available to the PAB project by the collectors and handed over to Rachel Bynoe for detailed analysis of the lithics and identification of the fossil material. The artefact assemblage is dominated by hard hammer flakes and cores, though there are also eight handaxes. Among the mammal fossils are several specimens that are identifiable to species, including the extinct horse Equus altidens, the mammoths Mammuthus meridionalisand Mtrogontherii, the extinct elk Cervalces latifrons and giant deer Megaloceros dawkinsi. 

Importantly, all the finds were geolocated by the collectors using hand-held GPS devices. The location data was used to map all the finds in GISthe results of which showed some interesting spatial patterning. There are significant concentrations of lithics and fauna in close proximity to the known archaeological deposits at Happisburgh Site 1 and site 3 and in addition there is a substantial ‘hotspot’ at Eccles North Gap, which cannot be linked to any known occurrence of the Cromer Forest-bed Formation. While the concentration is partly the result of being ‘trapped’ up-drift of the most northerly of the Sea Palling rock reefs, it may indicate that there is an outcrop immediately offshore from which the artefacts are being eroded and transported only a short distance onto the beach. The distribution of the faunal finds also shows concentration close to Sites 1 and 3, but again there are other interesting patterns that might suggest as yet unidentified source deposits. 

The handaxe finds are also of interest. Only one, the Happisburgh handaxe, has been found in situ over the last 20 years, and this was associated with the Site 1 deposits. The discovery of several handaxes in the vicinity of Site 3, which has previously been considered as a core and flake assemblage, raises the question of whether they are an additional component of the Site 3 assemblage. Further handaxe discoveries in situ within the Site 3 deposits are needed to verify this. 

The intriguing possibility that there are archaeological deposits immediately offshore at Happisburgh is a question that Rachel Bynoe is currently investigating through her diving survey work with some promising initial findings. Onshore the collecting continues, with a growing band of enthusiastic collectors. More material has been discovered since 2017 and the diligence and persistence of the collectors who return to the beach again and again has been amply rewarded by the creation of a substantial body of information that has contributed to our understanding of this important Palaeolithic locality.
