New Study Reveals Cold, Not Heat, Caused End-Triassic Mass Extinction

Research suggests rapid volcanic eruptions led to global cooling, paving the way for dinosaurs to thrive.

The End-Triassic mass extinction occurred 201.6 million years ago, eradicating about 75% of all species.
Previously believed to be caused by warming, new evidence points to volcanic winters as the primary driver.
Massive Central Atlantic Magmatic Province eruptions released sulfates, blocking sunlight and cooling the planet.
These eruptions were concentrated events, each lasting under a century, causing severe but short-lived cold spells.
Dinosaurs, already existing in smaller forms, survived and eventually dominated due to their adaptability to the cold.
