The post-glacial deposits of the Caldicot Level and some associated archaeological discoveries

The stratigraphy of the deposits is briefly described and the occurrence of Neolithic and Romano-British finds examined. The source of the Neolithic human skull found during the Newport Docks excavations in 1910, originally described as gravel, was almost certainly an overlying clay similar to that within which a second Neolithic skull was discovered at Newport in 1961. Archaeological finds suggest that some deposition of clay, following a rise in sea-level, has occurred since Roman times, though the magnitude of such a rise cannot be estimated until well-stratified datable remains are found.
