Asteroid's Timing Was 'Colossal Bad Luck' For The Dinosaurs

The asteroid that killed the dinosaurs struck at the worst time for them. A new study says if it had hit earlier or later, they might've survived.

Asteroid's Timing Was 'Colossal Bad Luck' For The Dinosaurs

We've all experienced bad luck before — lengthy traffic jams, alarms not going off, losing your cell phone or getting wiped out by a meteor, the usual stuff. Wait, what was that last one?

Dr. Steve Brusatte of Edinburgh University, who led the study, told Discovery the asteroid struck while Earth was undergoing climate changes caused by volcanic eruptions, tectonic events such as mountain formation and changing sea levels. This led to a weakened food chain as plant-eating dinosaurs died out.

"The asteroid almost certainly did it, but it just so happened to hit at a bad time when dinosaur ecosystems had been weakened by a loss of diversity."

The researcher believes had the strike happened a few million years earlier, before the Earth's climate changes, or a few million years later, the dinosaurs might have survived. (Via BBC)

Forbes quotes Brusatte saying, "Dinosaurs had been around for 160 million years, they had plenty of dips and troughs in their diversity but they always recovered."

So if the meteor struck a little earlier or a little later, would we be living alongside dinosaurs in the modern day? (Via Universal Pictures / "We're Back! A Dinosaur's Story")

Professor Simon Conway Morris doesn't think so. Conway Morris told BBC dinosaurs were less likely than animals, such as mammals, to develop intelligence. Eventually those species would get smarter and develop tools, and "from that moment the dinosaurs would have been toast."

On the other hand, study co-author Dr. Richard Butler of the University of Birmingham thinks differently, saying in a press release"Without that asteroid, the dinosaurs would probably still be here, and we probably would not."

​The asteroid struck the Earth at what is now the Yucatan Peninsula in Mexico. It left behind a crater 110 miles wide and 12 miles deep, leading to tsunamis, earthquakes, temperature changes and wildfires.
