Coastal landscape underlain by limestone which has been eroded by dissolution. Where known this has been subdivided thus: 1. Caves; 2. Sinkholes; 3. Solution pans; 4. Cockpits; 5. Karst cones; 6. Towers; 7. Boulder piles; 8. Tor; 9. Other. Note that we are using the term ‘sinkhole’ to include dolines, cenotes and swallow holes. Chronological information is presented as calendar age BP. Confidence is defined as follows: 1. High: Sampled feature with good age and palaeoenvironmental control. 2. Sampled feature with poor or none age and palaeoenvironmental control. 3. Constructed by remote sensing data only. 4. Low: Reasonable without any direct evidence.
