Terrestrial life oasis from end-#Permian mass #extinction period discovered
phys.org/news/2025-03-terrestr paper: science.org/doi/10.1126/sciadv

"a region in Turpan-Hami Basin served as a refugium for terrestrial #plants during the end-Permian #MassExtinction... The discovery provides the first conclusive fossil evidence of a terrestrial plant community that remained largely undisturbed throughout the extinction event, allowing for continuous evolution and rapid ecological recovery afterward."

The ecology and geography of #temnospondyl recovery after the #Permian–#Triassic #MassExtinction royalsocietypublishing.org/doi

"the #temnospondyls success lay in their generalist feeding ecology, enabling them to feed on a wide variety of prey... the freshwater habitats they preferred provided them with a relatively stable variety of food resources"

Plants struggled for millions of years after the world's worst climate catastrophe
phys.org/news/2025-03-struggle

"#conifers were some of the earliest to colonize the land after the End-#Permian catastrophe. But the recovery of #forests was not smooth sailing... even higher temperatures during the Late Smithian Thermal Maximum caused the collapse of these survivors... they were replaced by tough, shrubby #plants resembling modern #clubmosses. This scorching period lasted for about 700,000 years"

Glossopteris es un género fósil de hojas del Pérmico (298-251 MdA) cuyos árboles probablemente alcanzaban 30 metros de altura, con troncos de 80 cm de diámetro. 70 de sus especies se han encontrado en el subcontinente indio, pero lo importante es su presencia en Sudamérica, África, Madagascar, el subcontinente indio, Australia y la Antártida, demostrando que formaban parte del continente de Gondwana. 📷Bloopityboop #permico #permian #plantas #plants

Therapsids Originated in Tropical Rather than Temperate Regions sci.news/paleontology/mallorca

Early–middle Permian Mediterranean gorgonopsian suggests an equatorial origin of therapsids nature.com/articles/s41467-024

"#Therapsids were a dominant component of #Permian terrestrial ecosystems, eventually giving rise to #mammals during the early #Mesozoic... #Paleontologists have discovered a #NewSpecies of early #gorgonopsian #therapsid that was part of an ancient summer wet biome of equatorial #Pangea"

the #permian basin, which is like half of US total oil production is mostly 35-45API oil. all these refineries at the gulf coast, they produce diesel, fuel oil for shipping and heavy industry, the lifeblood of the economy, from 25-35API oil.

this will become more of a problem over time, as all the conventional fields in the US which produce the medium gravity oil are in decline. if anything that makes the US more depended on countries like #canada, not less.

About 252 million years ago, most species on land and in the ocean became extinct. 90% of life on Earth was wiped out by the #GreatDying at the end of the #Permian period.

#Volcanoes have long been a suspect in this paleo murder mystery. But they were likely not alone: a mega #ElNino event that lasted for decades might have set off a series of events that jumped #CO2 concentration in the atmosphere from 410 ppm to 800 ppm and increased global mean temperature by 4 °C.

Eos · Mega El Niño May Have Led to Major Mass Extinction 252 Million Years AgoBy Rebecca Owen

Mikko Tuomi

At the end of the #Permian, around 252 million years ago, volcanoes in the Siberian Traps spewed lava over an area almost the size of Australia, igniting massive wildfires, burning vast oil and coal deposits, and pouring #greenhouse gases into the #atmosphere.

After such apocalypses, Earth’s #climate typically reverts more or less to normal within 80 000–200 000 years, thanks to the interaction of the global carbon and silica cycles via #silicate weathering.

Eos · Clays May Have Slowed Earth’s Recovery After the Great DyingBy Kate Evans

There’s been no doubt for some time that we’re in the middle of a sixth #mass #extinction. Here are some numbers.

If we’re very lucky, we’ll stop at the level of the #Devonian extinction, the least severe of the Big Five. More likely we’re headed for something on the scale of the #Ordovician or #Triassic. The #Cretaceous is in sight, and the #Permian is not out of reach. From an evolutionary time perspective it will look like the Cretaceous, practically as instantaneous as the Big Rock.

I confess, I really like the idea of #corvid #paleontologists digging up the #Anthropocene. Feathers gleaming under badlands dust, exciting cawing as dextrous claws scrape rock away from a flat-faced skull … But I’m very much not okay with what we’re doing right now to make that happen.
