The catastrophic collapse that paved the way for the dinosaurs
In short: Before the age of giants began, Earth faced a near-total biological wipeout. This video explores the extreme environmental conditions that decimated ancient life and allowed the most iconic prehistoric creatures to eventually rise from the ashes.
Approximately 252 million years ago, a lethal combination of intense heat and low oxygen levels triggered a global cataclysm. The devastation was profound: an estimated 95% of all marine species were destroyed, while two-thirds of terrestrial life vanished.
Despite this near-extinction event, life persisted. From these remnants, dinosaurs eventually evolved to become the dominant rulers of the planet for millions of years.
