Beginning with two papers on the osteoarchaeological analysis of human bones and artefacts recovered from 24 Irish caves between 1870 and 1990, this volume presents detailed studies of nine artefact assemblages. Among the objects discussed are Neolithic and Bronze Age pottery; polished stone axe heads; perforated marine shells; perforated and worked animal teeth; early medieval and medieval pottery from sea caves along the Antrim coast; and Viking-age artefacts.
