Three new finite radiocarbon dates Suggest that (i) the thermnal maximum of the Port Talbot interstadial ocurred prior to 47,000 years before the present and (ii) the interstadial deposits were overridden by a glacial advance approximatels 44,000 years before the present. To facilitate correlaltions with other areas, new rock-stratigraphic names are proposed for the Port Talbot type section.
