Sclerochronology is the record of different periodicities expressed as chemical and physical variations in mineralized endo- or exoskeletons of living, fossil, and even extinct aquatic organisms.

Sclerochronological periodicities are documented in growth increments of different shapes and sizes, depending on the time span they represent (Schöne and Surge, 2005). Such increments may portray days, lunar cycles, months, or years. Their individual width and pattern reflect either specific taxonomically related and therefore biologically controlled signals or environmental conditions in which the organism grew. These skeletal chronologies may comprise individual lifetimes of organisms ranging from several decades to several hundreds of years. Prominent organisms are scleractinian corals, calcified sponges, mollusk shells, or otoliths from fish. Along with the record of growth increments, the chemical composition of the mineralized skeleton based on elemental ratios such as Sr/Ca and Mg/Ca or ...
