Can you imagine a world in which palm trees grew in Alaska and
there were coral reefs in the mountains of Canada? Well, the world
of the dinosaurs was much warmer than it is today and the climate
suited them perfectly. Many different types of dinosaurs lived
together, from the Brachiosaurus (as tall as a four-story building
and heavier than ten adult elephants) to dinosaurs no bigger than a
chicken. Some of these were ferocious meat-eaters and some were
gentle giants that ate only plants. Over millions of years the
landscape changed and so did the creatures that roamed the land.
And then, the dinosaurs died out! What happened to them? Do you
have any theories? But what if there was still one left alive and
you were lucky enough to keep a baby dinosaur as a pet?
