21 июн 25100000 г. до нашей эры - Permian-Triassic Extinction

Описание:

The Permian-Triassic extinction (also called the Great Dying, ~252 million years ago) was the most severe mass extinction in Earth's history, wiping out about 90% of marine species and 70% of terrestrial species. It marked the end of the Paleozoic Era and drastically reshaped life on Earth.

Causes:
Massive Volcanic Eruptions – The Siberian Traps released vast amounts of CO₂ and methane, triggering global warming.
Ocean Anoxia & Acidification – Reduced oxygen levels and increased acidity devastated marine life.
Climate Change – Extreme warming led to habitat loss and desertification.
Methane Release – Melting of methane hydrates intensified greenhouse effects.
