The largest extinction the world has ever known occurred at the end of which period?
The largest extinction event known is the Permian-Triassic Extinction Event, 250 million years ago. It is nicknamed "The Great Dying" in reference to how 96% of all known marine animals and 70% of all known terrestrial vertebrates at the time went extinct due to climatic changes because of volcanic eruptions and the formation of Pangaea.

Yes, trilobites were still present in the Permian, but at much lower numbers and diversity. Only the Order Proetida remained. The Permian ended with a mass extinction, and among the many groups which went extinct at the end of the Permian were the last trilobites. See Related Links below.

How does the background rate of extinction differ from mass extinctions?
The background rate of extinction is much smaller than those that occur during a mass extinction. For example, carnotaurus sastrei went extinct during the mid-Cretaceous, when only a handful of dinosaurs went extinct. On the other hand, 65 million years ago, all dinosaurs went extinct during the K/T mass extinction event.
