Twenty Palaeolithic sites have been identified in the Mendips, of which eleven represent faunal remains and lithic artefacts recovered from caves. The remaining eight sites refer to surface lithic discoveries, and the artefacts found include points, scrapers, and handaxes. Twenty-seven Mesolithic finds are represented by flint and chert lithics. Large numbers of artefacts have been found near Neolithic, Iron Age, and Bronze Age features, such as the barrows and forts around Priddy and at Dolebury Warren. The caves of Cheddar Gorge have yielded many archaeological remains, as flood waters have washed artefacts and bones into the caves and preserved them in silt. The Cheddar Man, Britain's oldest complete skeleton, was found in Gough's Cave, part of the Cheddar Complex.
