Data for: Chronology and eccentricity phasing for the Early Turonian greenhouse (~93-94 Ma): constraints on astronomical control of the carbon cycle. Paleoceanography and Paleoclimatology.

Here we present geochemical and geophysical data obtained from four boreholes in the Bohemian Cretaceous Basin (central Europe). These data cover the Lower Turonian interval (~93 and 94 Myr ago) and were used to develop a refined chronology and interpret the phasing of orbital eccentricity in this interval.
