As figured by dinosaur artist and scientist Gregory Paul in his now out-of-print text Predatory Dinosaurs of the World, an adult T. rex had the capacity to take a bite out its prey one yard long by one foot deep. The ability to scoop such a trough from the side or flank of a prey animal lends support to the theory that T. rex hunted in a fashion similar to that of a great white shark, i.e. by creating a massive wound in one strike and then trailing far behind the prey until it bled to death, thereby avoiding a nasty entanglement with the prey's horns, armor, claws, etc. This would be important, as theropod bodies in general were fairly rigid and relatively lightly built, not well-suited to taking a spill from their normal bipedal posture.
