Repeated anoxia-extinction episodes progressing from slope to shelf during the latest Cenomanian

► Changes in redox conditions, extinctions and SST spanning the OAE2 are clarified. ► In depth-transect analyses presented. ► Extinctions correlated to repeated oceanic anoxia. ► Extinctions started from the continental slope and moved to the continental shelf. ► This was the result of the repeated progression of euxinic-anoxic water.
