In Investigating T. Rex’s Teeth, Jack Horner, one of the world's most respected paleontologists, discusses how the teeth of T. rex were the wrong shape for it to be an effective predator. This video is excerpted from BBC's Horizon: T. Rex, Warrior or Wimp?, a documentary featuring interviews with T. rex experts from around the world and exploring the science behind the legend of the dinosaur we love to hate.
