The dinosaurs once lived happily on the earth. But 65 million years ago, they suddenly died out. What
happened to them?
Scientists think that a change in temperature may be to blame. They have come up with lots of ideas
to explain the end of the dinosaurs.
The most famous one is the minor planet (小行星) idea. Let"s go back to that day 65 million years ago
to see what happened. Everything was OK before a large minor planet suddenly hit the earth. What a
terrible hit! It caused big fires, storms, acid rain (酸雨), and even earthquakes and volcano eruptions. The
hit produced a lot of dust, which flew up into the air and blocked the sun for months. The earth became
very cold without sunlight. The plants died first. Then the grass eating animals died of hunger. Then the
meat eating animals could not find food, either. They began to eat each other, but after a while they died
out, too. The dinosaurs, either plant-eaters or meat-eaters, did not live through the disaster. What a sad
story !
In April, a British scientist thought of a new idea about the death of the dinosaurs.
He thinks that after the minor planet hit the earth, the temperature change left more dinosaur
boys than girls! Without enough female dinosaurs to hatch the eggs, the dinosaur population became
smaller and smaller.
