Abstract

We report here that shells of the marine bivalve mollusc Arctica islandica, collected near King Edward, Scotland, yield isoleucine epimerization D/L ratios only slightly higher than ratios in late-glacial specimens of the same taxon collected from nearby sites. We have determined the ages of two of the King Edward shells by tandem-accelerator mass spectrometry (TAMS) radiocarbon dating to be >40kyr. From the difference in D/L ratios, we calculate the average temperature depression during the last glaciation to have been ≥9 °C below Holocene temperatures.
