Dinosaur Facts



Page 1

Dinosaurs began to appear more than 200 million years ago. There were no humans in the world at that time.



Page 2

The word dinosaur in Greek means “wondrous lizard.” Until the 1970s, most scientists believed that dinosaurs were slow. Now, scientists know that dinosaurs were very quick and active.



Page 3

Some dinosaurs were carnivores. This means that they only ate meat.



Page 4

Other dinosaurs were herbivores. So, they only ate plants.



Page 5

Some herbivorous dinosaurs had spines and horns. The spines and horns protected the herbivores from the carnivorous dinosaurs.



Page 6

Brachiosaurus was one of the largest dinosaurs. It weighed over 40 tons. That means the brachiosaurus weighed the same as 500 humans!



Page 7

Brachiosaurus were also one of the tallest dinosaurs. They were more than 12 meters tall!



Page 8

Some dinosaurs were not smart. Others were kind of smart. But even a smart dinosaur was not as smart as a dog or a bird today.



Page 9

Dinosaurs laid eggs. The eggs usually were thicker and bigger than a chicken’s egg. And sometimes, the eggs were round, like balls.



Page 10

Most dinosaurs had long tails. These tails helped them keep their balance when they walked or ran.



Page 11

This is a pterosaur, which is Greek for “winged lizard.” Pterosaurs lived with dinosaurs. And pterosaurs could fly!



Page 12

Dinosaurs became extinct 65 million years ago. This means that they all died.



Page 13

Most scientists think that a giant comet or asteroid hit the earth and wiped the dinosaurs out.



Page 14

A few scientists think that many volcanoes erupted and wiped the dinosaurs out.
