my life's work as someone who definitely didn't go to college and will have no impact on the earth is largely ignoring the existence of the Jurassic and Cretaceous period in order to prop up the history of life on Earth that is not the constantly presented non-scientific dinosaurs depicted in every piece of popular art. I do not wish to speak of the Triceratops, I wish to speak of when nearly all life onland was Lystrosaurus, big old cow-like synopsid with fangs. get your sauropods out of here, i want to talk about when crocodiles had land genuses and how we almost lived in a world where some still survived. i never want to see a fucking t-rex ever again, but the world should be as obsessed with sloth bears like megatherium as i am. get these fucking dinosaurs out of my face i want OTHER EXTINCT ANIMALS TO TAKE THE SPOTLIGHT AND I WILL BREAK THE WORLD IN ORDER TO SHOW YOU ALL----

Nautilus’ and Ammonites incredible ability to survive in low-oxygen climates (how some ammonite species survived the Permian extinction)
Some species of ammonites were able to survive the Permian Extinction (which killed around 90% of Earth’s species). How did they do this? Even the trilobites disappeared after their reign of about 300 million years! Well, why don’t I first explain what scientists hypothesize what might have caused the Permian Extinction. The pores of fossilised leaves suggest that carbon dioxide levels were high about 250 million years ago, following a colder period of time (the pores, or stomata, of leaves take in CO2 so fewer pores means more CO2 in the atmosphere and vice versa). A rapid and sudden drop in sea levels at the end of the Permian ruined shore and near-shore habitats which destabilized the climate. The death of the many inhabitants of those habitats cause mass decomposition. The process of decomposition causes carbon dioxide to be released which then causes a depletion of the available dissolved oxygen and global warming. Near the end of the Permian, there was also intense volcanic eruptions for a couple million years, causing an initial cold snap but then global warming and ozone depletion. The effect of these events cause the oceans to become incredibly anoxic, so most ocean creatures likely suffocated. Of course there are other possible occurrences that could have contributed to the mass extinction, but these are the main ones. Now, how did some ammonite species survive? Using nautilus’ scientists discovered that their shell can function like a Scuba tank. Nautilus’ can counter low oxygen environments by slowing down and lowering its chemical activity. The nautilus can also collect oxygen in its buoyancy chambers in which they then use the stored oxygen to breathe. Fossil evidence suggests the ammonites also had the ability to do this.

sometimes i worry that our rising earth temperatures could lead to a great dying 2.0: man-made edition. then i remember that all those big bugs didn't have any warning. they were just out there being bugs. truly burdened by knowledge with 250 million years of hindsight
#guys guys 80% of marine life just DIED#70% of terrestrial vertebrates#WE'RE vertebrates#it was more than the bugs!!!!!#it was EVERYONE#and now we are just hairless monkeys way in over our heads#permian extinction#permian triassic extinction event#the great dying

Some of my favorite permian period creatures:
- GORGONOPSIDS
- Coelurosauravus
- Eryops
- Dimetrodon
- Lystrosaurus
- Scutosaurus
Also Heliocoprion gets a shoutout here because of how terrifying that creature looked.
What are your favorite ancient Permian creatures?

The first "big event" I can think of that makes me think "that really sucked. It's bad that that happened" is the Permian-Triassic Extinction Event, wiping out most of Earth's life 252 million years ago. The first "big event" I can think of that makes me think "that was cool. It's a good thing that that happened" is the Reforms of Solon, establishing a more-or-less democratic Athens 2617 years ago.
Feels a little asymmetrical.

Would the end-permian mass extinction, also known as The Great Dying, pay child support?

Ya know, I get that mass extinctions happen in an evolutionary blink of an eye, but they didn’t happen in a literal blink of an eye. I want more documentaries that take place during these extinctions. Show me what life was like during the Great Dying, don’t just tell me. Show me the survivors of Chicxulub and how they did or didn’t survive through Impact Winter.

Results from the #paleostream which turned into a post-extinction stream after the first sketch that shows a Sharamynodon. It is followed by Moschorhinus, Cimolestes and Eubaculites.

The great dying: Permo-Triassic extinction | A grande morte: Extinção Permo-Triássica
🇬🇧
The Permian-Triassic Extinction is the most devastating mass extinction event in Earth's history, occurring approximately 252 million years ago, at the end of the Permian period and the beginning of the Triassic period. This mass extinction resulted in the loss of up to 96% of marine species and 70% of terrestrial species.
The exact causes of the Permian-Triassic Extinction are still debated among scientists, but several theories have been proposed. One of them is intense volcanic activity, such as the massive eruption of the Siberian Traps, a large volcanic province in Russia. This activity released huge amounts of greenhouse gases into the atmosphere, causing drastic climate change and ocean acidification.
These catastrophic events caused widespread mass extinctions, affecting both marine and terrestrial organisms. The recovery of biodiversity after the Permian-Triassic Extinction took millions of years and profoundly influenced the subsequent evolution of life on Earth.
The relationship between the Permian-Triassic Extinction and current climate events can be observed through similarities in causative factors and consequences for life on Earth. Similarly, contemporary climate events are largely influenced by human activities, particularly the burning of fossil fuels, which releases greenhouse gases into the atmosphere. This anthropogenic activity has led to global warming, changes in precipitation patterns, rising sea levels, and ocean acidification, among other impacts. These changes are putting immense pressure on ecosystems and biodiversity, leading to species extinctions and ecosystem degradation. Both the Permian-Triassic Extinction and current climate events highlight the profound impact that changes in climate can have on life on Earth. Understanding the parallels between these events can help inform efforts to mitigate the current climate crisis and protect the planet's biodiversity and ecosystems.

A Extinção Permiano-Triássica é o evento de extinção em massa mais devastador da história da Terra, ocorrido há cerca de 252 milhões de anos, no final do período Permiano e início do período Triássico. Esta extinção em massa resultou na perda de até 96% das espécies marinhas e 70% das espécies terrestres.
As causas exatas da Extinção Permiano-Triássica ainda são objeto de debate entre os cientistas, mas várias teorias foram propostas. Uma delas é a atividade vulcânica intensa, como a erupção em massa dos Trapps Siberianos, uma grande província magmática na Rússia. Essa atividade liberou enormes quantidades de gases de efeito estufa na atmosfera, causando mudanças climáticas drásticas e acidificação dos oceanos.
Esses eventos catastróficos causaram extinções em massa generalizadas, afetando tanto organismos marinhos quanto terrestres. A recuperação da biodiversidade após a Extinção Permiano-Triássica levou milhões de anos e influenciou profundamente a evolução subsequente da vida na Terra.
A relação entre a Extinção Permiano-Triássica e os eventos climáticos atuais pode ser observada através de semelhanças nos fatores causadores e nas consequências para a vida na Terra. Da mesma forma, os eventos climáticos contemporâneos são amplamente influenciados por atividades humanas, particularmente a queima de combustíveis fósseis, que libera gases de efeito estufa na atmosfera. Essa atividade antropogênica tem causado o aquecimento global, mudanças nos padrões de precipitação, aumento do nível do mar e acidificação dos oceanos, entre outros impactos. Essas mudanças estão exercendo uma pressão imensa sobre os ecossistemas e a biodiversidade, levando a extinções de espécies e degradação dos ecossistemas. Tanto a Extinção Permiano-Triássica quanto os eventos climáticos atuais destacam o profundo impacto que as mudanças climáticas podem ter na vida na Terra. Compreender os paralelos entre esses eventos pode ajudar a informar esforços para mitigar a atual crise climática e proteger a biodiversidade e os ecossistemas do planeta.
