Below New Seawall LR 54 – Erosion patterns on the surface of a seashore limestone pavement below the new sea wall at Church Cliff in Lyme Regis, Dorset, UK, in June 2017, showing a patchwork of irregular shallow depressions caused by a combination of chemical (acid water) erosion and bio-erosion (mostly holes made by marine worms and scrapings by limpets). Photographed June 2017.
