The Oceanic Anoxic Event 2, at the Cenomanian-Turonian boundary (∼93.9 Ma), was an episode of widespread burial of organic matter in marine sediments, underlined by a positive carbon-isotope (δ13C) excursion observed worldwide. Within this episode

The Cenomanian-Turonian boundary (~94 Ma) was marked by an episode of widespread organic carbon burial largely associated with low oxygen concentrations in bottom oceanic waters, named Oceanic Anoxic Event 2 (OAE 2). In the Vocontian Basin (SE France
