Travel back to the time when the mighty dinosaurs ruled the earth.
The Age of Dinosaurs began about 250 million years ago. In the beginning they
were quite small but over time they evolved into the varied and fascinating
creatures that captivate our imaginations today. What we know about dinosaurs is
evolving, too! We've learned that some dinosaurs were good parents, that
dinosaurs could grow new teeth when old ones fell out, and that most dinosaurs
walked on two legs. We've even discovered that birds are modern relatives of
dinosaurs!
