Official Tyrannosaurus model by Sergi Suriol
Tyrannosaurus really needs no introduction. It is the most famous dinosaur of all time and has become a household name, and for good reason: it is truly the ultimate terrestrial macropredator. Tyrannosaurus is noteworthy for its unprecedented mass, reaching up to 10 tonnes, making it the largest terrestrial carnivore ever. While other theropod predators like Torvosaurus, Mapusaurus and Spinosaurus may have been equal or exceeded it in length, none reached the remarkable bulk of Tyrannosaurus.
Tyrannosaurus was more then well-armed for hunting. It's eyesight and sense of smell were fantastic. Its arms, despite being puny, were unusually strong. And best of all, it had evolved bone-crushing jaws so powerful that its bite force was equivalent to the entire animal sitting on you. Unlike the jaws of, say, Allosaurus, which were designed for tearing flesh (which would be very useful when hunting sauropods), Tyrannosaurus' bite was designed to crush bone. This emphasis on girth shows that this animal was specifically evolved to hunt the equally powerful and bulky hadrosaurs, ceratopsians, and ankylosaurs it shared its world with.
Tyrannosaurus will be the main focus of Dinosauria's final episode, showing the last hurrah of a mighty, scarred old male and that this amazing predator was certainly more then a ferocious killing machine.
