Just a selection of surprisingly well preserved limpet shells, probably Patella vulgata Linnaeus, from an archaeological excavation of a medieval UK east coast town. They are about 900 years old and were found in a food rubbish pit dug between the 12th and 13th centuries. The shell sculpturing survives but the surfaces have lost their sheen and colour. These are now matt and dusty due to partial denaturing of the shell – the organic lattice of the shell structure has disappeared, leaving just the mineral components.
