They say there are different theories why the dinosaurs are not alive anymore.
One of the theories is that a meteor crashed into the earth, its impact was so massive that it caused volcanos to erupt which then went into the sky and ash and rock fell dfrom the sky. Which would have suffocated the dinosaurs.
They also may their might have been a desiese which wiped them out because they didn't have good immune systems.
