The tyrannosaurs were the most deadly hunters of the entire 165-million-year Mesozoic era- the age dinosaurs. The biggest and most famous of them, tyrannosaurus rex, evolved near the end of the era, a few million year before the global catastrophe that wiped out all the giant dinosaurs, it was specialized for killing –inflicting huge bites that crippled its prey or caused it to die of shock. It would then rip its victim apart, biting out great chunks of meat and swallowing them whole.

Bone – crushing teeth

   Tyrannosaur teeth were bigger and stronger and stronger than those of any meat-eating dinosaur found so far. The biggest were at least 20cm (8in) long. They were more like spears than teeth- sharp-pointed to pierce thick skin and muscle, yet deep-rooted and very tough to give them the strength to bite clean through the bones of their victims.

Shock tactics

   Typical carnivorous dinosaurs had teeth like knife blades, ideal for slicing through skin and flesh. But these blade-like teeth were quite slender, and likely to snap off if the dinosaur bit into something hard. Tyrannosaurs and its relatives were different. Their teeth were sturdy spikes that could punch through virtually anything. This allowed tyrannosaurs to charge straight into the attack on their powerful hind legs. Most of the dinosaurs they preyed upon didn’t stand a chance.
