Death of the Dinos

1. Death of the Dinos Some different possible causes of the fall of the dinosaurs

2. Introduction • Dinosaur bones were probably found thousands of years ago, Greeks and Romans may have found bones and thought they were mythical creatures’ bones. • For a long time, scientists have been trying to find the reason why dinosaurs aren’t around anymore. • There are many theories of why dinosaurs became extinct, but none have yet been proved to definitely be the reason for dinosaur doom.

3. The Different Possible Deaths

4. Meteor Strike • Most people think a meteor killed the dinosaurs. • The collision had so much force, there was enough dust thrown into the air to block the sun. • The weaker dinosaurs died because of the change of climate. • Without the sun, plants struggled and eventually died out. • Without plants, herbivores died. • Without herbivores to eat, carnivores died too.

5. Volcanoes • Some people think a lot of volcanic eruptions killed the dinosaurs. • They believe enough ash was flung into the air to block the sun, leading to the same consequences as the meteor strike.

6. Ice age • Another theory is an ice age freezing the dinosaurs. • Many dinosaurs died of freezing. • In the extreme cold, water would have frozen. • With nothing to drink, the rest of the dinosaurs died.

7. Disease • Another possibility is that dinosaurs caught a severe sickness and couldn’t survive. • The disease would have been deadly and contagious.
