Millions of years ago the earth had many large creatures roaming it, they were called dinosaurs. There are none left today, why not we ask?
There are many theories as to why dinosaurs are extinct, these are three common ones.
Firstly a red fiery meteor hit the earth. The meteor made a lot of dust and fire. The dinosaurs got injured or were burnt.
Secondly there was no food for the plant eaters to eat because the fire burnt all the plants. They starved to death, leaving less dinosaurs for the meat eaters to eat.
Lastly there was no water because the lakes and ponds were filled with dust and dirt from the meteor.
There are no more dinosaurs left today and those were my three reasons why dinosaurs are extinct.
