Facts about Jurassic World and Tyrannosaurus Rex

Jun. 16, 2022

Last weekend, Jurassic World 3 was screened. After four years, people saw ancient dinosaurs on the movie screen again, including the Wind God Pterosaur, Velociraptorblue and Tyrannosaurus Rex. The most striking is of course the Tyrannosaurus Rex, and today we are going to talk about the facts about the Tyrannosaurus Rex.


Not the Jurassic Period

Despite the famous and popular depictions of Tyrannosaurus Rex in the Jurassic Park and Jurassic World movies, Tyrannosaurus Rex did not actually exist during the Jurassic period.

Tyrannosaurus rex lived at the end of the Late Cretaceous period, about 90 to 66 million years ago. Although other species of predatory dinosaurs may have existed during the Jurassic period (which ended 150 million years ago), Tyrannosaurus was not one of them!



Sharp teeth

The lower jaw of T. rex had about 60 serrated teeth, each as sharp as a knife. Tyrannosaurus rex teeth would protrude about 6 inches, about the size of a banana, perfect for grabbing, tearing and throwing prey into the air before capturing and swallowing it whole.

The largest T. rex tooth found was 30 centimeters long - as long as a standard ruler!


Tyrannosaurus rex are predators

Their powerful jaws and impressive teeth made Tyrannosaurus rex a formidable hunter, and it is perhaps not surprising that they were carnivorous. It is unclear whether T. rex hunted alone or in packs, but they certainly devoured other dinosaurs. Scientists believe that Tyrannosaurus rex also removed and stole prey from other predators, and there is even evidence that they may have eaten each other!


Tyrannosaurus rex skull

The longest T. rex skull  found was 1.3 meters long (over 4 feet) and the skull was so thick it could be crushed. Having such a large skull meant that T. rex had a relatively large brain compared to other predators, suggesting that they were intelligent hunters. Their skulls contained an exceptionally large cavity to accommodate the part of the brain responsible for smell, which meant they could easily spot food and other predators.



They may be slow

While we don't recommend testing this theory to find out, the Tyrannosaurus Rex likely moved much slower than movies like Jurassic Park would have us believe.

The skeleton of the 7-ton Tyrannosaurus Rex could not have withstood the speed depicted while chasing that jeep. Running too fast would have put tremendous stress on its bones and put it at risk of shattering. We now know that it ran at a maximum speed of about 12 mph.


One of the largest land predators

Weighing 7,000 kg and standing 12 feet tall, Tyrannosaurus rex was one of the largest land predators ever recorded. In fact, at 40 feet long, T. rex was the size of an American school bus. Quite huge!

But, in reality, T. rex was not the largest land predator ever recorded. The title of largest land predator of all time actually belongs to the giant Spinosaurus, which weighed at least 7 tons, stood 12 feet tall, and was an impressive 60 feet long.
