We present data that characterizes the net history of continental sedimentation. We show that this sedimentation history covaries with the history of pO2. We develop a forward pO2 model based upon this empirical history. This model predicts two rises in pO2 separated by three stable plateaus. These results suggest that modes in continental sedimentation dictate pO2.
