They were central to the existence of the Plains people. Then from 1830 to 1889 they neared extinction, with less than 1,000 still roaming.

They are often huge. They are meat eaters or plant eaters. But they do not exist any more. What killed the dinosaurs?Evidence(证据) shows that a huge meteor(陨石) hit the earth about 65 million years ago. It raised millions of tons of dust into the sky, caused volcanoes to erupt(火山爆发), acid rain(酸雨) and even tsunamis(海啸). Scientists think that all the dinosaurs died because of these changes to the environment.What does the word dinosaur mean and how are dinosaurs named?Sir Richard Owen coined(造字) the word dinosaur, meaning fearfully(极) great lizard, in 1842. In Greek, deinos means fearfully great and sauros means lizard. There are many different ways to choose a dinosaur name. Sometimes the dinosaur is given a name that describes something unusual about its body, head or feet. Some are named after the location(位置) where they are found. Others are named for their behaviour(行为) or size, and some are named to honour(尊敬) a person. The name has to be approved(批准) by the International Commission on Zoological Nomenclature(国际动物学命名委员会).

I rarely lie down and usually sleep standing up. I have a large body with wrinkled skin and tusks made out of ivory. I also have a very long nose that I use to smell, make trumpet calls, rip leaves off trees and spray water on myself. I am gray, tan or light brown with yellowish-white tusks.

I eat as much as 500 pounds (about 225 kilograms) of food each day! And 50 gallons (almost 90 liters) of water! My meals include leaves, grasses and other plants. My only real enemies are human hunters who value my ivory tusks. Even though I cant walk very fast, I have few enemies that are wild animals.
