Jurassic (callovian) paleotemperatures from Scotland

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 in¹⁸O compared with co-existing belemnites, which give mean temperatures of around 22°C, consistent with the Skye belemnite analysed by Urey et al. [1]. Possible reasons for the ammonite-belemnite difference are discussed.
