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.
The Early Triassic lasted between 252 million to 247 million years ago, [23] and was a hot and arid epoch in the aftermath of the Permian Extinction. Many tetrapods during this epoch represented a disaster fauna, a group of survivor animals with low diversity and cosmopolitanism (wide geographic ranges). [24]

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 ...
The 2020 East Troublesome Fire was a massive and destructive wildfire, and the second-largest in the history of the U.S. state of Colorado.Named for the East Fork of Troublesome Creek, close to the fire's point of origin in the Arapaho National Forest, the fire burned 193,812 acres (78,433 ha) between its ignition on October 14, 2020, and its containment on November 30.
Immediately above the Permian–Triassic boundary the glossopteris flora was suddenly [42] largely displaced by an Australia-wide coniferous flora. No known coal deposits date from the start of the Triassic Period. This is known as the Early Triassic "coal gap" and can be seen as part of the Permian–Triassic extinction event. [43]
The investigation into the cause of the most destructive wildfire in Colorado history, which forced tens of thousands of people to flee their homes ahead of the new year, remains ongoing as a new ...
