The worksheets provide students with inquiring questions about dinosaurs. These aren’t your basic information sheets.

The word Dinosaur, itself, translates into "terrible lizard" in the Greek Language. Dinosaurs are thought to have roamed the Earth until about sixty-five million years ago when a mass planet extinction event is thought to have occurred. The most commonly accepted theory is that a massive asteroid plunged to Earth kicking up enough dust and rubbish to block the Sun light from reaching the Earth's surface. This complete lack of sunlight resulted in a huge change of the planet's ecosystem.

These worksheets look at prehistoric life and the way dinosaurs made their way. We look at classes of dinosaurs and how they made their way around.
