How did the ones enormous dinosaur skeletons get throughout the museum?
Long ago, dinosaurs ruled the Earth. Then, all at once, they died out. For thousands of years, nobody knew these giant creatures had ever existed. Then other people started finding fossils—bones and teeth and footprints that had turned to stone. Nowadays, teams of experts work together to dig dinosaur fossils out of the bottom, bone by fragile bone. Then they put the skeletons together again inside museums, to appear similar to the dinosaurs of millions of years ago.
