Extended Data Fig. 5: The deterioration of temporal match (Rho, logged y-axis) between genus extinction rates of all marine genera and extinction rates of only those genera represented by the classes (blue), orders (green) and families (orange) in our modern marine experimental database.

The time series of Rho values is shown from the median duration of classes, orders or families represented by modern experiments (number in myr). At that (earliest) point in time, the modern experiment-represented families, orders and classes make up 11.3%, 21.8% and 63.1% of total marine genera, respectively. The two extinction rate times series correlated are iteratively expanded back in time by one geological age from the Recent, Pleistocene 1 and 2, that is from the minimum sample size of 3 time bins for a correlation.
