Dinosaurs are a name we gave to a bunch of big and small life forms.

Dinosaurs did not live at the same time as us. This was a long, long time in the past.

Some dinosaurs ate plants. They had long necks to get to the top of tall plants.

Some ate flesh. The T. Rex was a big one that ate flesh.

It had big legs and a big skull.

We get facts about dinosaurs from bones. We dig them up from rocks and mud.

These bones are like stone. We can see the shape and size of a dinosaur from its bones.

We can make a guess about what it ate. This is a big job for docs who dig up bones.
