These are very small fossil snails that I have photographed and processed for Richard Preece. The scale is 2mm in length so you can see the challenge. They were done on a lightbox with LED lights each side to give pretty even illumination. They are mainly focus stacks. Their significance I believe is because they are related species found in England and Scandinavia supporting the belief that until the middle Pleistocene, Britain was a peninsula off Europe, connected across the Straits of Dover.
