Dinosaurs extinct through ‘colossal bad luck’
The prehistoric creatures might have survived the asteroid strike which led to their extinction if it had come slightly earlier or later in history, scientists found. But when the 10km-wide asteroid hit what is now Mexico some 66m years ago they were experiencing environmental upheaval which left them vulnerable.
The new study by an international team of palaeontologists led by the University of Edinburgh looked at an updated catalogue of dinosaur fossils, mostly from North America.
