Permian–Triassic boundary at Frazer Beach in New South Wales, with the End Permian extinction event located just above the coal layer [2]. Approximately 251.9 million years ago, the Permian–Triassic (P–T, P–Tr) extinction event (PTME; also known as the Late Permian extinction event, [3] the Latest Permian extinction event, [4] the End-Permian extinction event, [5] [6] and colloquially ...
The eruptions continued for roughly two million years and spanned the Permian–Triassic boundary, or P–T boundary, which occurred around 251.9 million years ago. The Siberian Traps are believed to be the primary cause of the Permian–Triassic extinction event, the most severe extinction event in the geologic record.
Wignall is well known for his research on extinction in the fossil record, [3] [9] particularly the Permian-Triassic mass extinction. [ 2 ] [ 10 ] [ 11 ] [ 12 ] He has published extensively on the importance of oceanic anoxia [ 2 ] [ 13 ] and high temperatures [ 14 ] [ 15 ] as kill mechanisms during this event.
A mass extinction occurred in the early Guadalupian before the larger Permian–Triassic extinction event. [14] This extinction was originally called Olson's Gap because it was thought to be a problem in preservation of fossils. Since the 1990s it has been renamed Olson's Extinction.
It was the most severe extinction event of the past 500 million years, wiping out 80% to 90% of species on land and in the sea. Mystery deepens over cause of Earth's worst mass extinction event ...

According to the book "Society of the Snow," upon which the movie was based, the survivors gather each year on Dec. 22, the first day of the rescue, to "hold a ritual commemoration." "All of them ...
