Earth history is different from ordinary history: it's much harder to nail down specific dates when everything happened millions of years ago and over huge, slow timescales. But it can be done, as shown by paleontologists who have pinpointed the exact date of the largest mass extinction to ever occur on earth.
The end-Permian mass extinction, which their study calls the “most severe biodiversity crisis in earth history,” wiped out 95% of marine life and 70% of life on land about 252.28 million years ago.
