In order to evaluate the potential of H. hygomii otoliths for strontium (Sr) isotopic studies, we first compare the Sr-87/Sr-86 ratio of current representatives of the species with that of modern sea water. Then, three fossil otoliths of H. hygomii collected in middle Miocene sediments of the Aquitaine Basin (Lafaurie locality, SW France) and the Carpathian Foredeep of the Central Paratethys (Brno-Kralovo Pole locality, SE Czech Republic) are analysed. The age inferred from the Sr-87/Sr-86 ratio at Lafaurie places the two analysed otoliths within the time interval of 15.5-15.1 Ma. This time interval matches the published early Langhian age obtained from the Sr-87/Sr-86 ratio of bivalves measured at the same locality. At the Brno-Kralovo Pole, the Sr-87/Sr-86 ratio of the analysed otolith returns a wider timespan of 14.78-13.10 Ma, falling into an interval of poor time resolution of the Sr-87/Sr-86 chemostratigraphy. Comparisons with published biostratigraphic and paleoclimatic data suggest that the analysed fossil otoliths of H. hygomii were mineralized during the late part of the Langhian, at 14.2 Ma. This work represents a first attempt to use otoliths for Sr-87/Sr-86 chemostratigraphy, and indicates that such a use may represent a powerful tool for testing stratigraphic correlations in the future.
