The Bedout impact coincides with the Permian–Triassic extinction event, the period known at the end-Permian where 90% of Marine and 80% of land life disappeared.
It has been suggested, that Methanosarcina's newfound ability to produce methane was the cause of the Permian–Triassic extinction event.

Absaroka sequence, a cratonic sequence that extended from the end of the Mississippian through the Permian periods
Selwyn Rock (an exposed Permian glacial pavement) at Inman Valley in South Australia, Selwyn Range in the Canadian Rockies and Selwyn Street in Hackett, a suburb of the Australian Capital Territory are named after him.
There are no indications of inversion during the Variscan Orogeny, but the fault was reactivated in a normal sense during the Permian and Triassic and again during the Cenozoic with a sinistral strike-slip sense.
While other groups of crinoids flourished during the Permian, bourgueticrinids along with other extant orders did not appear until the Triassic, following a mass extinction event in which nearly all crinoids died out.

In Paleorrota geopark, located in Brazil, were found rare branches of the genus Buriadia, are in the Rio Bonito Formation and date from Sakmarian in the Permian.
Like all Chroniosuchians, they bore extensive osteoderm armour on their backs, possibly as protection against terrestrial predators such as the Permian therapsids and the Triassic Rauisuchians.

James Lovelock's book "The Revenge of Gaia" suggests that Gaia has many mechanisms for eliminating civilisations that do harm through greenhouse gas emissions and global warming, but suggests that with increasing heat being received from the sun, Gaia's ability to "bounce back" as it did after the Permian and Cretaceous extinction events, may be increasingly compromised.

An opposite view is that humankind is Gaia's immune system itself, perhaps evolved to avert future catastrophes such as the Permian and Cretaceous mass extinctions of species.
Permo-Triassic age rocks are known to lie beneath Point of Ayre but, as with the rest of the northern plain, these rocks are concealed by substantial thicknesses of superficial deposits.
As well as major contributions to stratigraphy and geological mapping, G. N. Frederiks is particularly remembered for his contributions to the paleontology of the late Paleozoic era (Carboniferous and Permian periods), notably Brachiopoda, Ammonoidea, and Bryozoa.
That specimen was found in Wolfcampian age quartzites exposed on China Mountain, six miles southeast of Contact, Nevada.
The northern group of the Permian dialects (upon Kösva, Kama and Lup rivers) was under a strong Zyrian influence on all the levels.
There are many interesting geological features: Hronov-Porici fault, old mines and exposure of Permian-Mesozoic rocks.
The Monuran trackway is a fossil trackway in the Robledo Mountains of New Mexico, produced by the extinct insect group called Monura, (meaning "one-tail"), from the Lower Permian.
Early or basal Permian neodiaspids were lizard-like, but already include specialised swimming Claudiosaurus and gliding Coelurosauravidae forms, as well as more conventional lizard-like forms (Youngina etc.).
The commune occupies an ancient volcanic plateau which has been coated at the edges with Permian sandstone deposits which become thicker to the south and east in the Permian basin of Saint-Dié.

Orthacanthus was featured in the Shark Week special "Prehistoric Sharks", where it was labelled as the terror of permian swamps.
By Permian times, the monsoon circulation is apparent in the lithology.
Cycas first appeared in the back some 280 million years ago Earth Paleozoic Permian.
It owes its name to the fact that its jaw was found near the fossils of a Permian pareiasaur named Anthodon.
It is clear that these animals evolved from Nycteroleterids, perhaps a Rhipaeosaur-like form to fill the large herbivore niche(or guild) that had been occupied early in the Permian period by the Caseid pelycosaurs and before then the Diadectid amphibians and Edaphosaur reptiles.
Permian bronze casts were produced by the Komi and Udmurt people between the 4th and the 14th centuries.
Sir A. Geikie has shown that the puy type of eruption was common in the British area in Carboniferous and Permian times, as abundantly attested in central Scotland by remains of the old volcanoes, now generally reduced by denudation to the mere neck, or volcanic vent, filled with tuff and agglomerate, or plugged with lava.
A single specimen is known, collected from the Texas Permian redbeds by Charles Hazelius Sternberg in 1917.
Tate gave special attention to the Recent and Tertiary mollusca of Australia, and discovered evidence of Permian glaciation of southern Australia at Hallett Cove.
The corals which build reefs today, the Scleractinia, arose after the Permian–Triassic extinction event that wiped out the earlier rugose corals (as well as many other groups), and became increasingly important reef builders throughout the Mesozoic Era.
American paleontologist Alfred Romer used the term in a similar sense, grouping most Permian and Triassic temnospondyls under Rhachitomi.
The River Otter rises in the Blackdown Hills just inside the county of Somerset, England near Otterford, then flows south for some 32 km through East Devon to the English Channel at the western end of Lyme Bay, part of the Jurassic Coast, a UNESCO World Heritage Site. The Permian and Triassic sandstone aquifer in the Otter Valley is one of Devon's largest groundwater sources, supplying drinking water to 200,000 people.
A famous locality that yielded numerous excellently preserved fossils of Sclerocephalus is Odernheim am Glan in Rhineland-Palatinate (Germany), where the Permian sediments of the Rotliegend have even been named "Stegocephalenkalke" (= Stegocephalia limestones).
He is on the board of the Permian Playhouse, the Odessa Cultural Council, and Meals on Wheels.
It lived during the latest Permian, and was a contemporary of Inostrancevia, Scutosaurus and Dvinia.
However, there are already other suggested candidates for giant impacts at the Permian–Triassic boundary, for example Bedout off the northern coast of Western Australia, although all are equally contentious, and it is currently under debate whether or not an impact played any role in this extinction.
The Xidagou Formation is an Middle Permian-age geologic formation in the Qilian Mountains of Gansu, China.
