The Early Toarcian Oceanic Anoxic Event (OAE), as defined by both relatively high total organic carbon (TOC) values and ammonite and nannofossil biostratigraphy, is clearly synchronous across Europe and will undoubtedly prove to be so in global context [1].
The Bilong Co oil shale zone is also of special interest because the organic geochemistry of organic-rich oil shale can be correlated with that of the Early Toarcian anoxic event in Europe [8].
Geologic survey and preliminary analysis of the oil shale samples show that the Bilong Co oil shale was deposited in a relatively anoxic marine environment in terms of its biomarkers [10] and could be correlated with that of the Early Toarcian anoxic event in Europe [11].
