Giant teeth! Crushing bite! Slicing claws! And ... feathers? Scientists have unearthed new knowledge about the king of the dinosaurs, and now you can, too. Travel back in time to the Mesozoic forests to meet the mighty Tyrannosaurus rex. Learn how their bodies were perfectly adapted for hunting, how T. rex parents guarded their nests, and just how much meat they could guzzle down in a single bite. Then explore some of the fascinating fossils--including Sue and Scotty--that have helped scientists make important discoveries (for example, T. rex may not have roared at all!).
