The extinction was triggered by a vast eruption of the Siberian Traps, a gigantic and prolonged volcanic event that covered much of modern day Siberia, which led to a cascade of environmental effects.
The Late Permian: The Late Permian mass extinction around 252m years ago dwarfs all the other events, with about 96% of species becoming extinct.This event coincided with the Emeishan eruption in what's now China, and is known to have caused simultaneous extinctions in the tropics and higher latitudes. The Middle Permian: Scientists have recently discovered another event 262m years ago that rivals the 'Big Five' in size.Once you've accessed the interactive street view of your location, look in the upper left hand corner of the screen and you'll see a small clock symbol next to a date. This extinction has been linked to major climate change, possibly caused by an eruption of the volcanic Viluy Traps area in modern-day Siberia. A major eruption might have caused rapid fluctations in sea levels and reduced oxygen levels in the oceans. Google has announced that starting today you can travel to the past to see how a place has changed over the years via Street View in Google Maps for desktop.

The Late Devonian: This period is now regarded as a number of 'pulses' of extinction spread over 20m years, beginning 380m years ago.This makes it the only major extinction to be linked to global cooling. The Late Ordovician: This ancient crisis around 445m years ago saw two major waves of extinction, both caused by climate change associated with the advance and retreat of ice sheets in the southern hemisphere.Next to the time it was taken, an option for 'See more dates' should appear.
Traditionally, scientists have referred to the 'Big Five' mass extinctions, including perhaps the most famous mass extinction triggered by a meteorite impact that brought about the end of the dinosaurs 66 million years ago.īut the other major mass extinctions were caused by phenomena originating entirely on Earth, and while they are less well known, we may learn something from exploring them that could shed light on our current environmental crises.
