Scientists call it the Permian-Triassic extinction or "the Great Dying" -- not to be confused with the better-known Cretaceous-Tertiary extinction that signaled the end of the dinosaurs 65 million years ago. Whatever happened during the Permian-Triassic period was much worse: No class of life was spared from the devastation.
The scientific consensus is that the main cause of extinction was the flood basalt volcanic eruptions that created the Siberian Traps, [19] which released sulfur dioxide and carbon dioxide, resulting in euxinia and anoxia, [20] [21] elevating global temperatures, [22] [23] [24] and acidifying the oceans.cause a mass extinction.
