🦖Giant reptiles, pterosaurs, and dinosaurs once ruled the planet for more than 100 million years.
🌍The mystery of their extinction began when scientists discovered a layer of dark clay.
🌪️High levels of iridium in the clay suggested an asteroid impact 65 million years ago.
💥The impact caused a catastrophic event, blocking out the sun and leading to the extinction of plant and animal life.
🔍Scientists continue to search for a crater to confirm the asteroid impact.
What caused the extinction of dinosaurs?
—An asteroid impact 65 million years ago caused the extinction of dinosaurs and many other species.
How did scientists discover the asteroid impact?
—Scientists found a layer of dark clay with high levels of iridium, which suggested an extraterrestrial impact.
What were the effects of the asteroid impact?
—The impact caused a catastrophic event, blocking out the sun and leading to the extinction of plant and animal life.
Is there a crater from the asteroid impact?
—Scientists are still searching for a crater to confirm the asteroid impact.
What other evidence supports the asteroid impact theory?
—Shocked quartz and glass-like beads found at the K/T boundary provide additional evidence of the impact.
