How did those enormous dinosaur skeletons get inside the museum? Long ago, dinosaurs ruled the Earth. Then, suddenly, they died out. For thousands of years, no one knew these giant creatures had ever existed. Then people began finding fossils -- bones and teeth and footprints that had turned to stone. Today, teams of experts work together to dig dinosaur fossils out of the ground, bone by fragile bone. Then they put the skeletons together again inside museums, to look just like the dinosaurs of millions of years ago.

Dinosaurs are extinct now, but you can visit dinosaur skeletons in a museum. There you will meet Brachiosaurus, Stegosaurus, and Diplodocus and learn how they ruled the earth millions of years ago. You'll see dinosaurs with over 1,000 teeth, dinosaurs who could swim, meat-eaters and plant-eaters. And, of course, you'll meet the king of all dinosaurs, the gigantic Tyrannosaurus rex.
