The Cretaceous-Tertiary extinction event, or the K-T event, is the name given to the die-off of the dinosaurs and other species that took place some 65.5 million years ago. For many years, paleontologists believed this event was caused by climate and geological changes that interrupted the dinosaursâ food supply.
Extinctions can happen for many reasons but recently people have been a major cause. Over hunting can led to extinction as can diseases, climate change or habitat loss which is when animalâs homes are destroyed. In the past, there have been very large extinctions where many species have gone extinct together. This is called an extinction event. One of these events wiped out the dinosaurs. 65 million years ago, all dinosaurs (except birds) went extinct as did many other types of plants and animals.
