1. Dinosaurs By: Jason W. Gager

2. Introduction  Dinosaurs were either herbivores or carnivores.  They have been extinct for millions of years.  We study their fossils to learn all that we can about them.

3. Their Habitat  They had the whole earth to themselves.  They migrated to stay in warm climates and in search of food.  Some lived in the oceans while others lived on land.

4. Scientific Names  The names we use for the dinosaurs today were chosen and given to them by scientists as they discovered their fossils.  The large fossil to the right is a Tyrannosaurus Rex.  The smaller fossils in front of him are Velociraptors.

5. Extinction  Scientists believe that the dinosaurs we study all died off millions of years ago when a large meteor fell from space.  This meteor hit the ground and made a large dust cloud which cooled off the earth, blocking the sunlight from reaching the ground.  The dinosaurs died of the cold and lack of food as nothing new could grow without the sun.
