A meteor that hit southern Alberta around the time dinosaurs were the only citizens of what would become Calgary would have wiped out all life nearby.

CALGARY -- The fireball streaking across the sky would have been visible for hundreds of kilometres and when it finally hit, the blistering shockwave would have obliterated Calgary and everything else in the vicinity.

Luckily for mankind, witnesses to the massive meteorite strike 200 kilometres southeast of Calgary were limited to late-era dinosaurs like Tyrannosaurs Rex, or to early Cenozoic mammals, such as Prothryptacodon albertensis, a hoofed carnivore.

It's good timing for humans, because anything within a couple hundred kilometres or so -- including Calgary -- would have been cooked alive in a blast 200 times stronger than the most powerful nuclear device ever detonated.

"If it happened today, Calgary would be completely fried and in Edmonton, every window would have been blown out," said Doug Schmitt, Canada Research Chair in Rock Physics at the University of Alberta.
