Dinosaurs lived long ago. One kind of dinosaurs lived in a desert (沙漠). One of these dinosaurs wanted to lay eggs. It made a hole in the sand (沙子) and put the eggs inside. It covered them with sand. A strong wind started to blow. It blew and blew. More sand blew over the eggs. Soon the eggs were buried (埋) in the sand.
A long, long time went by. There were no more dinosaurs. But there was still a desert. And the eggs were still there. But they changed. They turned to stones! Some people came to the desert. They were looking for old things. They found the stone eggs. Before that, no one knew how dinosaurs were born. But now we know that.
