“…The city-size asteroid that slammed into Earth with the force of a million nuclear bombs is what snuffed out the dinosaurs and half of all other species on Earth 65 million years ago, an international group of scientists who reviewed all available evidence said today…”
It seems a new study has re-confirmed the theory that the dinosaurs were wiped out by a huge asteroid impact.
National Geographic Article: Asteroid terminated dinosaur era in a matter of days
“The impact hypothesis has grown stronger than ever.”
USA Today Article: Scientists conclude asteroid, not volcanoes, wiped out dinosaurs
Makes you wonder how many theories can be formed about an extinction event/cause.
Enjoy…
