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 Permian–Triassic extinction event, labeled "End P" here, is the most significant extinction event in this plot for marine genera which produce large numbers of fossils The Permian ended with the most extensive extinction event recorded in paleontology : the Permian–Triassic extinction event . 90 to 95% of marine species became extinct ...
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.

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]
It is preceded by the Wuchiapingian age/stage and is followed by the Induan age/stage (Early Triassic epoch). [4] The greatest mass extinction in the Phanerozoic eon, the Permian–Triassic extinction event, occurred around the end of this age.
The End Permian extinction or the "Great Dying" occurred at the Permian–Triassic transition. [13] It was the Phanerozoic Eon's largest extinction: 53% of marine families died, 84% of marine genera, about 81% of all marine species [ 14 ] and an estimated 70% of terrestrial vertebrate species. [ 15 ]
The Permian–Triassic extinction event is the most significant event for marine genera, with just over 50% (according to this source) perishing.
