Quizplus · Accepted Answer

The current scientific consensus is that a meteor impact at the end of the Cretaceous era caused a massive cooling event that resulted in the extinction of the dinosaurs. This theory is supported by a range of evidence, including the discovery of a crater that is believed to have been caused by the impact. Other factors, such as disease or competition from mammals, may have played a role in the dinosaurs' decline, but the meteor impact is widely regarded as the primary cause of their extinction.
