'Colossal bad luck' led to extinction of dinosaurs

LONDON: Dinosaurs might have survived if the asteroid that killed them had struck slightly earlier or later, according to a new study led by British scientists. It was the "bad luck" that wiped out the prehistoric creature which dominated the earth for around 160 million years.

An international team of paleontologists led by the University of Edinburgh studied an updated catalogue of dinosaur fossils, mostly from North America, to create a picture of how dinosaurs changed over the few million years before the asteroid hit.
