Quizplus · Accepted Answer

The most widely accepted theory for the cause of the Cretaceous mass extinction is that an asteroid or comet impact caused a global catastrophic event that led to the extinction of the dinosaurs and many other species. This theory is supported by the discovery of a massive impact crater in Chicxulub, Mexico, which dates back to the same time period as the extinction event.
