Ghosh, Prosenjit; Prasanna, K; Banerjee, Yogaraj; Williams, Ian; Gagan, Michael; Chaudhuri, Atanu; Suwas, Satyam


The Cretaceous greenhouse climate was accompanied by major changes in Earth’s hydrological cycle, but seasonally resolved hydroclimatic reconstructions for this anomalously warm period are rare. We measured the δ18O and CO2 clumped isotope Δ47 of the seasonal growth bands in carbonate shells of the mollusc Villorita cyprinoides (Black Clam) growing in the Cochin estuary, in southern India. These tandem records accurately reconstruct seasonal changes in sea surface temperature (SST) and seawater...[Show more]
