The Day the Dinosaurs Died – Minute by Minute

Summary by Krater

This video explains the catastrophic asteroid impact that ended the dinosaur era 66 million years ago, detailing the sequence of global disasters from the initial shockwave and mega-tsunamis to massive wildfires and years of darkness that wiped out 75% of species.

From the video

Answers: What actually happened when the asteroid hit the Earth and wiped out the dinosaurs?

• Dinosaur extinction asteroid impact
• Chicxulub asteroid collision effects
• Global wildfire spread after asteroid impact
• Mega-tsunami generation and propagation
• Impact winter and photosynthesis shutdown

What it concludes

• An asteroid larger than Mount Everest struck the Yucatan Peninsula 66 million years ago, releasing energy equivalent to billions of nuclear weapons.
• The impact triggered a magnitude 11 earthquake, massive lava flows in India lasting 30,000 years, and mega-tsunamis reaching up to one kilometer high.
• Debris ejected into space fell back through the atmosphere, heating the air to temperatures comparable to an industrial oven and igniting global wildfires.
• Soot from burning forests and aerosols generated at impact blocked sunlight, shutting down photosynthesis for years and causing global temperatures to drop by 25 degrees Celsius.
• The lack of sunlight killed over 90 percent of ocean plankton, collapsing marine food webs and leading to the extinction of 75 percent of all species on Earth.
• Without the asteroid impact and the end of the dinosaur era, modern humans and the current animal kingdom would not exist.
