Pardon!

摘要

The dinosaurs, famously, went out with a bang. Some 65.5m years ago, at the end of the Cretaceous period, the Earth collided with an asteroid and the biggest terrestrial beasts in history were no more. That left things clear for the rise of the mammals. But how did the dinosaurs rise to power in the first place? Some light on this question has just been shed by a paper published in Science by Micha Ruhl of Utrecht University, in the Netherlands, and his colleagues.
