  2. Permian–Triassic extinction event - Wikipedia

    en.wikipedia.org/wiki/PermianTriassic...

    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. Ichthyosauromorpha - Wikipedia

    en.wikipedia.org/wiki/Ichthyosauromorpha

    The presence of such a derived ichthyosauromorph so early in the Triassic indicates that the ichthyosauromorphs (and possibly ichthyosauriformes, depending on divergence estimates) originated during the Permian and were thus survivors of the mass extinction as opposed to ecological successors that evolved following it. [1]

  4. Galesauridae - Wikipedia

    en.wikipedia.org/wiki/Galesauridae

    Galesaurid fossils are found almost worldwide. They were among the survivors of the Permian-Triassic extinction event, but they became extinct in the Middle Triassic epoch, as did the therocephalians. Genera of the family Galesauridae include the namesake Galesaurus.

  5. Hovasaurus - Wikipedia

    en.wikipedia.org/wiki/Hovasaurus

    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.

  6. 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]

  7. 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.

  8. 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 ...

  9. Mesozoic - Wikipedia

    en.wikipedia.org/wiki/Mesozoic

    The era began in the wake of the PermianTriassic extinction event, the largest mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, pterosaurs, mosasaurs, and plesiosaurs. The Mesozoic was a time of significant tectonic ...
