Short summary
Isotopic signatures of ostracods from Florida correlate with their host water, implying a regional influence of temperature and precipitation. Calculated monthly configurations of a theoretical calcite formed in rivers were compared to ostracod isotope compositions. The data suggest a seasonal shell formation during early spring that is coupled to the hydrological cycle of the region. The surprising seasonality of the investigated ostracods is of importance for paleontological interpretation.
