After getting some information about dinosaurs from the encyclopedia (百科全书), Mary got interested in these animals. She surfed the Internet and found a lot more about dinosaurs. Here’s what she wrote in her notebook.

General information

Millions of years ago, long before there were any people, there were dinosaurs. They existed (存在) on earth for about 165 million years and suddenly died out (灭绝) 65 million years ago.

Fun facts
Size
◆The largest dinosaurs were more than 30 meters long and up to 15 meters tall.
◆The smallest dinosaurs were about the size of a chicken and had very long tails. They ate insects (昆虫).
Egg
◆Most dinosaurs were hatched (孵化) from eggs.
◆The biggest dinosaur egg ever found was the size of a football.
◆There were egg-eating dinosaurs that stole eggs from other dinosaurs’ nests (巢穴).
Brain
◆A lot of dinosaurs have big heads, but they didn’t have much brain inside. Most of the space was taken up with muscle (肌肉) and bones instead.
Tail
◆Dinosaurs that used their tails to beat their enemies had four feet and ate plants.
◆Dinosaurs that used their tails for balance (平衡) had two feet and two small arms, and they were often meat-eaters.
Discovery
◆From looking at bones, scientists can figure out (弄清楚) the shape of the dinosaur’s body.
◆There were more than 800 different kinds of dinosaurs.
Conclusion

We can only know about the lives of dinosaurs from the fossil (化石), eggs and footprints they left behind. But we still don’t know how they sounded, how they behaved, what colors they were and so on.

Oh, my God! Dinosaurs are the most mysterious animals in the world!
