1.The T-Rex was named by Henry Fairfield Osborn in 1905 while he was serving as the president of the American Museum of Natural History.

2. The name Tyrannosaurus rex comes from the Greek words 'tyranno' and 'saurus'. 'Tyranno' means "tyrant" and 'saurus' means "lizard". In Latin, 'rex' means "King". The words combined means "tyrant lizard King" which we think is pretty accurate!

3. The largest ever T-Rex skeleton covered was named Sue and measured up to four meters tall, 12 meters long and weighed nine tons. She was found in South Dakota, USA. There is no complete T Rex skeleton in existence, but Sue got pretty close with 90% of her bones living in Field Museum.

4. Sue sold for five million pounds in 1997 to a museum in Chicago.

5. Scientists still wonder why the T. Rex had two teeny tiny arms with claws. With such a big body, the size of their arms is a mystery but some scientists believe short arms are less likely to break and take less energy to support which can help keep the T. Rex the clear king.

6. T. Rexes and humans almost have the same number of bones with the huge dinosaur having 200 bones and humans having 206 bones.

7. The first ever documented remains of a T-Rex was found by Barnum Brown. Barnum Brown was one of the most famous dinosaur fossil hunters in all of history and was known as Mr. Bones.

Did you know that T-Rexes for all of their time on Earth were found across many continents? These interesting facts about Tyrannosaurus Rex and their habitats will sure make you glad these fierce predators aren't still around!

8. The T. Rex was alive during the Cretaceous period, roughly 65 to 70 million years ago and in the area that now makes up North America. At the time, this area was called Laramidia. There have even been fossils found in Wyoming and Montana!

9. Scientists believed that T-Rexes were only found in North America and Asia, but fossils have proven that there was actually a Tyrannosaurus Rex living in Australia!

10. Tyrannosaurus Rex habitats were mostly areas with plenty of forests and rivers because there were always lots of prey in these areas for them to hunt and gobble up.

11. Most T. Rexes died really young, often before the age of one due to problems like hunger, disease and fights with predators would result in death. The oldest T. Rex discovered so far only lived until 28, so they didn't live very long lives. This 28 year old fossil also showed that it had a lot of trauma in its lifetime which scientists think may be because of all of the fights they had, but it is not known for sure.

12. It took 100 million ears for the tyrannosaur family to evolve into the T-Rex. The T-Rex was one of the last dinosaurs before the event that made them all extinct.

13. Even though they were a fierce predator, the T-Rex was wiped out in the mass extinction event around 66 million years ago that destroyed three quarters of life on earth, including all the dinosaurs.

We've all seen T-Rexes in films like 'Jurassic Park', 'Ice Age', 'Night At The Museum', 'The Land Before Time' and many others, but how much do you actually know about what life was like for T-Rexes 65 million years ago?

16. The T-Rex had a big head which was balanced out by its big thighs and tail.

17. The T-Rex wasn't the fastest dinosaur, however, scientists believe they could run up to 25km/hr,  making them pretty fast in our opinion.

18. Not only was the T-Rex quick and powerful, they were also really smart with a brain that was double the size of other dinosaurs their size. This big brain gave the T. Rex stronger senses including great eyesight, hearing and smell.

19. Scientists say the T-Rex had the strongest bite of any animal in history. The bite was so strong the dinosaur could tear huge amounts of meat from a single bite with enough power to crush a car.

20. The T-Rex had great eyesight. Although 'Jurassic Park' shows otherwise, the T-Rex has two front facing eyes and scientist believe they had the ability to see colors like humans. Some scientists even think the T. Rexes, like birds, could see the ultraviolet colour range which is invisible to humans.

21. T-Rexes had binocular vision, meaning they were excellent at telling how far away their prey was and timing their attacks perfectly.  

22. T-Rex adaptations were what made these predators so powerful. For one, it had a bite so powerful, its force was 12,000 pounds, making it very easy to catch predators and rip them apart for dinner, not to mention their incredible vision.
