Short summary
The timescale of mixing and irrigation of sediments by burrowers that affect biogeochemical cycles is difficult to estimate in the stratigraphic record. We show that pyrite linings in molluscan shells preserved below the mixed layer represent a signature of limited bioirrigation. We document an increase in the frequency of pyrite-lined shells in cores collected in the northern Adriatic Sea, suggesting that bioirrigation rates significantly declined during the late 20th century.
