Isotopic paleotemperature analyses of belemnites and ammonites from the Belemnite Sands and Oxford Clay of Staffin Bay, Isle of Skye, are presented. Ammonites are depleted in 18O compared with co-existing belemnites, which give mean temperatures of around 22??C, consistent with the Skye belemnite analysed by Urey et al. . Possible reasons for the ammonite-belemnite difference are discussed. ?? 1970.
