    PermianTriassic 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 PermianTriassic (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 ...

  3. Lepidopteris callipteroides - Wikipedia

    en.wikipedia.org/wiki/Lepidopteris_callipteroides

    Lepidopteris callipteroides is a form species for leaves of Late Permian Pteridospermatophyta, or seed ferns, which lived from around 252 million years ago in what is now Australia, and Madagascar. Lepidopteris callipteroides was an immediate survivor of the largest Permian-Triassic extinction event , migrating southward with the post ...

  4. Therocephalia - Wikipedia

    en.wikipedia.org/wiki/Therocephalia

    Therocephalia is an extinct clade of eutheriodont therapsids (mammals and their close relatives) from the Permian and Triassic periods. The therocephalians ("beast-heads") are named after their large skulls, which, along with the structure of their teeth, suggest that they were carnivores.

  5. Permian - Wikipedia

    en.wikipedia.org/wiki/Permian

    The Permian (along with the Paleozoic) ended with the PermianTriassic extinction event (colloquially known as the Great Dying), the largest mass extinction in Earth's history (which is the last of the three or four crises that occurred in the Permian), in which nearly 81% of marine species and 70% of terrestrial species died out, associated ...

    Permian: PermianTriassic extinction event: 252 Ma Large igneous province (LIP) eruptions [23] from the Siberian Traps, [24] an impact event (the Wilkes Land Crater), [25] an Anoxic event, [26] an Ice age, [27] or other possible causes End-Capitanian extinction event: 260 Ma: Volcanism from the Emeishan Traps, [28] resulting in global cooling ...

  7. Triassic - Wikipedia

    en.wikipedia.org/wiki/Triassic

    Immediately above the PermianTriassic 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 PermianTriassic extinction event. [43]

  8. Moschorhinus - Wikipedia

    en.wikipedia.org/wiki/Moschorhinus

    Moschorhinus seems to have gone extinct in the Early Triassic at 251 mya after the Permian Extinction by 252 mya, [13] [14] [15] along with 80–95% of animal species, due to a mass hypoxia event. This appears to have led to stunted growth , [ 3 ] intense seasons, reduced ecosystem diversity, and a loss of forests. [ 4 ]

    Hovasaurus is an extinct genus of basal diapsid reptile.It lived in what is now Madagascar during the Late Permian and Early Triassic, being a survivor of the PermianTriassic extinction event and the paleontologically youngest member of the Tangasauridae.
