Front-on head profile of Tyrannosaurus rex. Most popular of all dinosaurs, this 42 foot predator has struck terror and awe into every child that has ever seen it. Tyrannosaurus possessed foot long, banana-shaped teeth, capable of puncturing through even the hipbone of a Triceratops. While its arms were very short, it has recently been hypothesized that they were actually used as grappling hooks, to hold prey in close while its huge head dispatched the prey.
