Oceanic Anoxic Event 2 (OAE 2), spanning the Cenomanian/Turonian boundary (93.9 Ma), was an episode of major perturbation of the global carbon cycle. Its geochemical signature is a synchronous positive δ13C excursion in both carbonates and organic matter that resulted from the net burial of large am...
