At the end of the Permian period, around 252 million years ago, approximately 70% of life on land and 90% of species in the oceans went extinct. Determining the cause of this extinction, which was the most severe in Earth’s history, requires a high-quality timeline of precisely when the extinction began and how quickly it progressed.
