T-Rex To Reveal Itself At the Smithsonian

"This week, scientists at the Smithsonian's National Museum of Natural History will start unpacking some rare and precious cargo. It's something the Smithsonian has never had before — a nearly complete skeleton of a Tyrannosaurus rex."

"Most people don't know it, but the T. rex that's standing tall in the Natural History Museum in Washington, D.C., is a fake — a cast, a copy of the bones. It's an accurate replica, but for decades the Smithsonian has coveted a real skeleton of a T. rex — the charismatic, 30-foot-long beast that's not only deliciously frightening to contemplate but also fascinating to scientists."

"How did such an animal grow so large? How fast did it run? Was it a predator or a scavenger?"
