Aside from being one of the largest of the known carnivorous dinosaurs, Tyrannosaurus rex — T. rex, for short — is the dinosaur that has arguably received the most media exposure. It had a starring role in Steven Spielberg’s Jurassic Park movies and is part of a renowned exhibit at the American Museum of Natural History in New York City.
See the fact file below for more information on the T. rex or alternatively, you can download our 22-page T. rex worksheet pack to utilise within the classroom or home environment.
Key Facts & Information
- COMMON NAME: Tyrannosaurus Rex (T. rex)
- SCIENTIFIC NAME: Tyrannosaurus Rex
- GENUS: Coelurosaurian Theropod
- TYPE: Prehistoric Animals
- DIET: Carnivores
- CONSERVATION STATUS: Extinct
SIZE and APPEARANCE
- Tyrannosaurus rex was one of the largest meat-eating dinosaurs that ever existed. Everything about this ferocious predator, from its thick, heavy skull to its 1.2-meter-long jaw, was designed for ultimate bone-crushing action.
- The largest and most complete T. rex skeleton found was nicknamed Sue, after its discoverer, paleontologist Sue Hendrickson. Measurements suggest T. rex was one of the largest carnivorous dinosaurs to ever live, coming in at up to 14 meters tall at the hips and 12.3 meters long.
- T. rex had strong thighs and a powerful tail, which counterbalanced its large head and allowed it to move quickly. Its muscle distribution and center of mass suggest that the giant could run 10 to 25 mph.
- According to the most recent studies, they are estimated to have weighed between 8.4 metric tons to 14 metric tons.
- The dinosaur’s bite could exert up to 12,814 pounds-force, which is roughly equivalent to the force of a medium-size elephant sitting down.
- T. rex had a mouth full of serrated teeth; the largest tooth of any carnivorous dinosaur ever found was 12 inches long.
- Its teeth were wide and somewhat dull, allowing the teeth to withstand the forces exerted by struggling prey.
- T. rex was a huge carnivore and primarily ate herbivorous dinosaurs, including edmontosaurus and triceratops.
- Scientists also believe that this powerful predator could eat up to 500 pounds of meat in one bite.
- Recent analyses also suggest that tyrannosaurus, while slower than large modern terrestrial predators, may well have been fast enough to prey on large hadrosaurs and ceratopsians.
- Tyrannosaurs eye sockets are positioned in the same way as modern predators, which have binocular vision. With eyes pointed forward, a T. rex’s vision was slightly better than that of modern hawks.
- Other studies also show some tyrannosaurus specimens with tooth marks in the bones, showing they were cannibalistic. The tooth marks were identified in the humerus, foot bones and metatarsals, and this was seen as evidence for opportunistic scavenging, rather than wounds caused by intraspecific combat.
- More mobile than many other land-based dinosaurs, T. rex roamed throughout what is now western North America, at the time an island continent identified as Laramidia.
- Other scientists also theorize that tyrannosaurus may have been pack animals. This was evidenced by early discovery of three sets of T. rex fossils within close proximity.
- It became extinct about 67 to 65 million years ago in the Cretaceous period – Tertiary mass extinction – towards the end of the Mesozoic era.
- During this period, animals included more flight birds and giant herbivores flourished with the T. rex as the apex predator.
- T. rex is by far the most popular dinosaur. It has been frequently represented in films and on television, in literature, on the Internet and in all kinds of games.
- New York Times hailed T. rex as “the most formidable fighting animal of which there is any record whatever,” the “king of all kings in the domain of animal life,” “the absolute warlord of the Earth,” and a “royal man-eater of the jungle,” thus gaining widespread public attention on December 30, 1905.
- T. rex has become so popular it starred in films of Peter Jackson, Steven Spielberg, Ray Harryhausen and has faced everyone from Batman, to King Kong, to Doctor Who, to The Ghostbusters, to Angel, to Homer Simpson.
- Its formidable appearance makes it an ideal opponent or nemesis with audiences.
- In the movie Jurassic Park 3, T. rex fans recreated heavily to the T. rex vs. Spinosaurus scene. They believed T. rex should have won. To console the T. rex lovers, Jurassic World finally hailed T. rex as the apex predator after defeating the I-rex.
- In some cartoons and animated shows, T. rex are similarly portrayed as the main villain, all thanks to their menacing appearance, as seen in Ice Age 3.
