The BBC reports on some research that suggests Dinosaurs might have survived the asteroid impact if it hadn't been for a combination of other factors.
The study brought together 11 leading dinosaur experts from the UK, US and Canada to assess the latest research on the extinction of dinosaurs 66 million years ago. There is evidence that some species of dinosaur were dying off shortly before an asteroid hit the Earth. One of the key questions was whether this gradual decline would have led to the extinction of these animals even if the asteroid had not hit.
Dr Steve Brusatte, of Edinburgh University, said sea level rises and volcanic activity had made many species more susceptible to extinction. They might have survived if the asteroid had hit the Earth a few million years later or earlier, he said, calling it "colossal bad luck."
The experts concluded that although some species of plant eaters in North America were dying out in the period leading up to the asteroid impact there was no evidence of a long-term decline. However, the experts believe that rises in sea level and increased volcanic activity made many species more susceptible to extinction just at the point that the asteroid struck.
