They then compared their model to the magnitude of past mass extinctions captured in the fossil record, especially to the End-Permian Extinction - Earth's deadliest extinction event so far.

This graph plots extinction rates of marine animal families over the last 600 million years. The shaded band indicates the normal range of extinction rates, known as "background extinction.
