Tyrannosaurus, also known as T-Rex or Tyrannosaurus Rex was a species of carnivorous dinosaur.


Massive carnivores, the Tyrannosaurus roamed the land looking for prey, which they could kill with a single bone-crushing bite, though catching prey was more an issue of stealth than of speed, for Tyrannosaurus was not the fastest runner. Equipped with a head full of bone-crushing dagger-like teeth, strong hind legs, two small forearms with two fingers each and a long, thick tail for counterbalance, the Tyrannosaurus filled the role of dominant predator among many dinosaurs. Like other dinosaurs, Tyrannosaurus were egg-layers.

Mother Tyrannosaurus, such as Momma, tended to their young, which hatched from eggs that were about three feet high, by taking them to sources of heat such as Lava Falls upon hatching and bringing the youngsters either carrion or stunned or dead small animals so that the babies would learn to hunt. Though, unlike other animals and like other dinosaurs, Tyrannosaurus could not speak in words, they were able to both understand and gesture in response to sentences and phrases spoken by other animals.


One Tyrannosaurus became encased in ice at some point, remaining frozen until the ice ages where it was frozen in a glacial cavern. Among the dinosaurs that went extinct during the cataclysms that struck the earth was Tyrannosaurus. A number of the Tyrannosaurus, however, had successfully found refuge in a vast underground world in which dinosaurs of all kinds had successfully survived.

Behind the Scenes

  • Momma, the tyrannosaurus depicted in the film Ice Age: Dawn of the Dinosaurs was approximately eighty feet long. In reality, tyrannosaurus was only about forty feet long. Actual T-Rex were 12 feet tall but for Momma shown to be about 25 ft tall and their weight of T-Rex shows to 7.5-9tons that will make Momma to be 15-18tons. It is possible that the oxygen down in the dino world could make several dinosaurs grow bigger than normal size.
  • Real tyrannosaurs likely had a covering of feathers adorning their bodies. However, this is a relatively new discovery which explains the lack of such integument in the film's portrayal.
