1. T-Rex dinosaurs roamed the Earth 65 million years ago

T-Rex dinosaurs inhabited our planet around 65 million years ago in the area that’s now known as the U.S. and Canada. The tyranosaurus family, which also includes the T-Rex dinosaur, was among the last dinosaurs about 80 million years ago. These giant predators on the ground were relatively short-lived, but they have had a big impact on today’s human understanding of dinosaurs. In fact specimens that’ve developed from these dinosaurs still exist, for example, in the form of lizards.

2. The name Tyrannosaurus Rex means Tyrant Lizard King

Tyrannosaurus Rex in translation from Greek and Latin means Tyrant Lizard King, emphasizing dinosaurs huge size and dominance towards all the other species.

3. The famous T-Rex could grow up to 12m long

Dinosaurs excite scientists and history enthusiasts with their huge sizes. Tyrannosaurus Rex was one of the largest dinosaurs on the planet, reaching a length of 12 m and a height of 6 m. Its weight reached about 6 tons and its heavy tail served as a steady stabiliser for this two-legged dinosaur.

4. T-Rex dinosaurs were dreadful carnivores 

Like today, several millions years ago, animals categorised into groups of carnivores  and herbivores. Although there were many herbivore dinosaurs eating from plants, T-Rex was not one of them. That is why this dinosaur has won the title of the most popular dinosaur, because of its fearsome teeth and predator lifestyle.

5. One T-Rex tooth by size is equivalent to one banana

The dinosaur-era king T-Rex had a jaw filled with 50-60 teeth, where the size of one tooth was equivalent to a medium-sized banana. Experts say these predators were able to rip off nearly 100 kg of flesh with one bite.

6. The brains of this predator were twice as big as other carnivors

While investigating the T-Rex skeleton, scientists discovered its brain size is 2 times larger than other predators of its time. Its big nasal cavity suggests that the T-Rex dinosaur has had a brilliant sense of smell that has helped in the hunt. It also had one of the largest eye holes, which makes us think that the T-Rex dinosaur also had brilliant vision. In addition, the skull shape also proves that the dinosaur’s eyes were more in the bow than other dinosaurs, providing T-Rex with a binocular, 3D-like vision.

7. T-Rex was capable of running at a speed of 20 km/h

Capable to reach the age of up to 28, Tyrannosaurus Rex was able to reach the speed of 20 km/h. Although they are not the quickest dinosaurs that existed (some were able to reach speed up to 60 km/h), they would certainly be able to catch a human being.

8. The little arms of the dinosaur still remain a mystery

While some scientists view the small arms of T-Rex as a result of an unfinished evolution, others think they have been useful for tearing up the prey. Despite the viewpoint that this dinosaur had small and weak hands, either way it ends up being 10 cm longer than an adult’s full-size hand.

9. More than 20 almost complete T-Rex skeletons have been found

More than 20 T-Rex skeletons have already been found. 20 years ago, the skeleton of the largest T-Rex dinosaur, whose remains are best preserved, was found. The size of this skeleton is 13 m long. Currently, the skeleton is in one of the U.S. museums. This T-Rex has been called Sue which indicates its gender being a woman, although it is still not clear whether the 13 m-long dinosaur was a representative of women or men.
