Indominus Rex: How it compares to real dinosaurs

Keep reading to watch this amazing video

Though humans need only examine the fossil record to see evidence of fearsome monsters like Tyrannosaurus rex and Giganotosaurus roaming the Earth. But sometimes, we want to create new nightmarish creatures to scare us, or imagine the perfect version of a terrifying monster.

The result of this line of thinking was Tyrannosaurus Rex, a devastating hybrid dinosaur that made its debut in Jurassic World . While the creature has never walked the Earth, this imaginary dinosaur showcases a nightmarish scenario in which one creature possesses all the strongest attributes of the other monsters.

We'll take a closer look at the I-rex and show you how it was measured, the dinosaur that helped make it a reality, and how it compares to the dinosaur it's based on, the T-Rex. We'll even weigh them in battle!

Why was Indominus Rex made?

Indominus Rex becomes the biggest and scariest attraction in New Jurassic World. Dr. Henry Wu is tasked with creating a hybrid dinosaur that has all the strongest and scariest aspects of the dinosaurs that were brought back to life in previous years.

The design of the I-rex has the hallmarks of the most successful carnivorous dinosaurs that ever existed. In that effort, Dr. Wu and his team of well-funded scientists succeeded.

How big is Tyrannosaurus Rex?

Indominus rex grows to 20 feet tall and 50 feet long. The I-rex dinosaur was designed by Dr. Henry Wu and is an amalgamation of several incredible dinosaurs

Additionally, the Indominus rex is capable of reaching speeds of 30 mph when running at top speed. The dinosaur was also agile, able to turn and accelerate to top running speed in tight enclosures.

The Indominus rex looks similar to the T-rex in many ways, including its overall shape and size. However, the I-rex differs from the T-Rex in many ways.

Indominus rex is larger than T-Rex and Giganotosaurus, with longer arms than T-Rex and spines on its neck and back. The I-rex also differs in color. Its base colors are off-white and gray. Thanks to its unique cuttlefish genes, the I-rex can quickly change its skin color and texture to suit its environment, creating camouflage in flight.

The dinosaur's camouflage played a role in the enclosures at Jurassic World, as well as in the forest surrounding the park.

The Indominus rex also has the benefit of advanced intelligence, as it received genes from dinosaurs for greater intelligence, memory and complex thinking. Not only is the I-rex built for strength, but it's also capable of hiding in plain sight, stalking, and planning attacks.

What is the DNA of Tyrannosaurus Rex?

Indominus rex has the DNA of Tyrannosaurus Rex, Giganotosaurus, Cuttlefish, Velociraptor, Viper, Majunsaurus, Carnotaurus, Tree Frog, and other creatures.

The I-rex is a theropod whose form is based on the T-Rex. I-rex has inherited a huge head and teeth from Giganotosaurus. Its back was covered with spines called ostioderms, which came from either Carnotaurus or Majunosaurus.

Unlike the T-rex's puny arms, the Indominus Rex has strong, agile arms derived from the Therizinosaurus genes, giving it another effective way to kill enemies.

Velociraptor DNA gave the I-rex incredible intelligence and agility, while the cuttlefish gave the dinosaur the ability to camouflage its enemies.

Essentially, the I-rex has the most powerful combination of traits and represents a super apex predator.

Indominus Rex vs Tyrannosaurus Rex: Who will win the battle?

Indominus rex would defeat Tyrannosaurus Rex in battle. The I-rex is built to be the most powerful predator on Earth, and we have a pretty good simulation in Jurassic World form of what would happen in that kind of fight, which is not good for a T-Rex.

Indominus rex is bigger, faster, and possibly longer. Its bite matched or exceeded the force of T. rex, and its teeth were designed to grab and crush prey, not slice it open. This means that the I-rex grabs something and bites its crocodile-like teeth deep into the prey without the prey escaping.

The I-rex can camouflage itself so well that it's nearly undetectable to modern technology, and its skin has been hardened to withstand gunshots and bites, including those from the T-rex!

The most likely outcome of this battle is that Tyrannosaurus rex quietly waits for the Tyrannosaurus rex to break into its territory. Then, it would lunge at the T. rex, ram it and grab the T. rex with its powerful jaws and long, sharp teeth.

Depending on the location of the bite, the fight may end immediately. A bite to the neck can be fatal. But, if not, the Tyrannosaurus rex fought back, using its teeth and short arms to fight back. However, the Indominus rex has stronger, longer arms that can inflict deep, brutal damage on enemies.

However, Tyrannosaurus rex is smart enough to realize that it has more strength, size and weight than T. rex. The dinosaur will change tack and drag the T-rex to the ground with all its might, where it will struggle under multiple attacks from the Indominus, ending its life.

With its immense strength, intelligence, defense and speed, Tyrannosaurus Rex can kill T-Rex.
