Sclerochronology is a methodological approach that uses the growth increments and geochemical signatures preserved in biogenic hard tissues—such as mollusk shells, corals, fish otoliths, and bivalve valves—to reconstruct chronological environmental and physiological records. By counting and measuring periodic growth bands (e.g., annual, seasonal, or daily) and analyzing stable isotopes, trace elements, and microstructures along these increments, researchers can derive high-resolution time series of parameters such as temperature, salinity, and growth rates. The method requires rigorous calibration of growth periodicity, precise sampling along growth axes, and robust chronological alignment to produce quantitatively reliable environmental and ecological reconstructions.
