The Tyrannosaurus rex (or "T rex," as he is often known) was one of the largest, fiercest, most powerful predators ever to roam the earth. At 50 feet high and a weight of 8 tons, this ferocious, carnivorous dino reigned supreme about 100 million years ago, in the Late Cretaceous Period. History buffs will surely love Skullduggery's tooth replica (at a fraction of the real size), fashioned from originals on display at the Museum of Geology of the South Dakota School of Mines and Technology in Rapid City, South Dakota. This 10-inch re-creation--the original was thought to have fallen out of the animal's mouth when he died and was found in a dried-up streambed back in 1981--even comes with its own stand and mini history booklet.
