Fossil beetles of Bognor Regis, West Sussex

David Bone (UK) Bognor Regis in West Sussex was wheret I spent my teenage years (a long time ago) and it is still a locality that I regularly visit and to where I also lead fossil hunting expeditions. Having said that, like many foreshore localities with no eroding cliffs, there are times when beach sand hides the underlying geology and a casual visitor can be very disappointed. Alistair describes the London Clay around the sandstone ‘Bognor Rocks’ and their many fossil molluscs, but he also briefly mentions that fossil beetles have been found at this locality. Bognor is one of very few places in Britain where Eocene fossil insects can be found and I have the privilege of being one of only a handful of people that have found them here. I believe that none have been found for at least 30 years due to lack of suitable foreshore exposures or, possibly, sufficiently dedicated collectors. My collections were mainly created in the 1970s and ‘80s, when ideal conditions periodically exposed large tracts of London Clay in the right area of foreshore known as the ‘Beetle Bed’, which is a narrow strip of clay just to the west of the Bognor Rocks (Fig. 1). Here, the London Clay (Division B) is a grey-brown, sticky clay, with occasional claystone nodules known as septaria. Fig. 1. Foreshore exposure of the Beetle Bed, London Clay, Bognor Regis in 1991.
