Organic carbon and total sulfur content and concentrations of selected molecular fossils for C/T black shales (Table 1) ...
During mid-Cretaceous times large amounts of organic carbon (Corg) became sequestered in 'black shales', possibly due to 'oceanic anoxic events' characterized by the development of an extended oxygen minimum zone (OMZ). Here, we provide the first direct evidence for an open ocean...
