Figure 5

Stratigraphic Mo curve for the fossiliferous interval 108.30–108.24 m (‘C7O3’). Note: The upper part is fully oxygenated (low Mo) and rich in Orusia brachiopods (high Ca). The lower part displays strong inverse relationship between Ca and Mo contents. It should be kept in mind that the brachiopod shells are curved and cross the bedding plane, which mixes oxygenated and anoxic intervals.
