Want to see firsthand how a dinosaur moved? Observe a bird as it walks along the sidewalk or in your backyard. Then challenge a friend to a "push-up" race—dinosaur versus crocodile.

Like today's crime-scene investigators, paleontologists study clues left behind. See firsthand what trackways—fossilized footprints—can tell them about dinosaur behavior.

Ever wish you could watch a dinosaur in action? Investigate modern birds for an insightful look at how ancient dinosaurs moved and behaved.

Travel to Liaoning, China, where a fossilized lakebed is providing scientists with the most complete picture to-date of what a dinosaur ecosystem probably looked like.

We know that some dinosaurs had fancy frills while others had sharp horns or pointy spikes. But why? Investigate the purpose of these and other dinosaur "fashions."

Re-create the 130-million-year-old forest in what is now China to understand why this fossil site is of such vast scientific importance.
