Short summary
The relative contributions of astronomical forcing and tectonics to ocean anoxia in the Cretaceous are unclear. This study establishes the pacing of Late Cretaceous black cherts and shales. We present a 6-million-year astrochronology from the Furlo and Bottaccione sections in Italy that spans the Cenomanian–Turonian transition and OAE2. Together with a new radioisotopic age for the mid-Cenomanian event, we show that astronomical forcing determined the timing of these carbon cycle perturbations.
