What happened to the dinosaurs?
The dinosaurs went extinct about 65 million years
ago, at the end of the Cretaceous period, which
was a time of high volcanic and tectonic
activity. There are a lot of theories why the
extinction occurred. The most widely accepted
theory is that an asteroid impact caused major
climactic changes to which the dinosaurs couldn't
adapt.
