Quizplus · Accepted Answer

The Permian period had the greatest rate of extinction, with approximately 96% of marine species and 70% of terrestrial species going extinct. This event is known as the Permian-Triassic extinction, or the "Great Dying." The other periods mentioned (Cretaceous, Devonian, and Cambrian) also had significant extinction events, but not on the same scale as the Permian.
