Additionally, geochemical analyses (δ 18 0, δ 13 C) were realized on oyster shells associated to the corals.
The results indicate that the mean values of paleotemperatures were around 22°C and it represents optimal
temperatures for zooxanthellate corals. However, considering the paleoenvironmental conditions and the
paleoecological assemblage, the corals of the Isle of Skye are regarded as having belonged to an extreme
ecosystem.
