Giganotosaurus is coming! After looking through this dinosaur blog, you will acquire 12 facts about Giganotosaurus thoroughly.

Did you watch the latest Jurassic World: Dominion released in June? If you do, you must know who is the final winner of Giganotosaurus vs. T. rex in Jurassic World.

However, how do you know about Giganotosaurus in reality? T. rex’s arch-enemy, Jurassic fiery killer, or giant southern lizard? The Giganotosaurus is the biggest meat-eating dinosaur from the late Cretaceous period. This massive creature has captured the attention of many people in recent decades.

Get ready with Only Dinosaurs to learn more facts about Giganotosaurus!

A quick preview of the facts about Giganotosaurus:

1. Giganotosaurus facts: Name Origin

Giganotosaurus was named in 1995 and is regarded as one of the largest meat-eating dinosaurs on our planet.

Some scientists think the name Gigantosaurus comes from a Greek word that means “giant southern lizard.” There is evidence that suggests the name Giganotosaurus may not even be related to the word “gigantic”.

Other words with related sounds might have contributed to the mistake. For instance, “Gantophis” is a huge prehistoric snake, and “Gigantoraptor” is a huge dinosaur with wings. In this case, it is important to distinguish Giganotosaurus from Gigantosaurus, a different sauropod found in England.

So, is Giganotosaurus real? Though the giant southern lizard can be found in the Giganotosaurus cartoon, it did exist 97 million years ago.

2. Giganotosaurus Pronunciation: How to pronounce Giganotosaurus?

It seems hard for most people to pronounce the names of dinosaurs. Giganotosaurus pronunciation sounds like jai·ga·nuh·tuh·saw·ruhs. You can watch the video provided below to get a more clear answer.

3. Giganotosaurus Size : How big is a Giganotosaurus?

From the name meaning, the question you care about most might be how big is Giganotosaurus? How tall is a Giganotosaurus? Is Giganotosaurus bigger than T-rex?

There has long been controversy over the size of Giganotosaurus, as the incompleteness of its remains has made it difficult to estimate its size reliably. The Giganotosaurus stands at a whopping 39–43 feet long and 23 feet high at the shoulders.

Measuring in at over 40 feet long, this massive beast was significantly larger than the king of the tyrant lizards, the T.rex. If you are interested in giant dinosaurs, check the blog Titanosaurs: Top 15 Biggest Dinosaurs of the World to know more.

Imagine realistic animatronic dinosaurs like the Giganotosaurus vs. T. rex appearing in a dinosaur theme park. That’s a pretty cool idea to recreate the Jurassic World scene!

4. Interesting facts about Giganotosaurus: It is lightweight for its size

The Giganotosaurus was an impressive creature, not only due to its size but also because its bones were hollow. This made it relatively lightweight for its size. When Giganotosaurus vs. T. rex is on weight, guess who will win?

The average Tyrannosaurus only weighed between 5,000 and 15,800 pounds. Giganotosaurus, on the other hand, ranged from 8,400 to 27,600 pounds. Given this difference in size, the Tyrannosaurus would find it difficult to defeat an adversary as large as the Giganotosaurus.

5. Interesting Giganotosaurus facts: How big is a Giganotosaurus brain?

Although Giganotosaurus has a huge skull, its brain measured 32mm long and 29mm wide, which is small and shaped like a banana.

Giganotosaurus has an appearance that is somewhat dull by late Cretaceous standards. Even though it was bigger and faster than many dinosaurs, it was not as intelligent.

Compared to its body weight, its brain was only about half the size of a T. Rex’s. So T.rex will win in the quotient competition (Giganotosaurus vs. T. rex).

6. Giganotosaurus Habitat: Where did Giganotosaurus live?

Giganotosaurus is a South American dinosaur that was only recently discovered. Its fossils have been found in Argentina and Chile, leading scientists to believe that it may have roamed the continent.

No matter where it came from, the Gigantosaurus is among the most impressive animals to ever exist. Rare animal alive today can match their size and strength. So, whatever you do, stay away from a Gigantosaurus!

7. Giganotosaurus Diet: What did the Giganotosaurus eat?

The diet of Giganotosaurus is not known. Some scientists have speculated that it may have been a pure carnivore. Several fossilized Giganotosaurus teeth suggest it hunted this enormous herbivore.

With its massive size and powerful jaws, this dinosaur was capable of taking down even the largest of prey. They probably ate meat-eating dinosaurs, such as Dilophosaurs, as well as smaller animals such as mammals, lizards, and other reptiles. Though it was primarily a carnivore, Giganotosaurus was also known to scavenge for food if necessary.

Then, How did Giganotosaurus hunt?

Despite the short arms, they were extremely powerful, making the Giga a truly ferocious predator. So, what was Giganotosaurus’s attack strategy?

It was believed that the Giganotosaurus used its extremely long and sharp teeth to cut into dense plant matter due to the shape of its jaw.

New evidence, however, raises the possibility that this largest meat-eating dinosaur hunted large sauropods. It would have been able to kill very large prey that its jaws couldn’t handle using this tactic.

Giganotosaurus is thought to have hunted in packs, as fossil evidence suggests its closely related cousin, Mapusaurus, did. Pack hunting would have been necessary to take down such enormous prey alone.

Certainly, this carnivore is set at the top of the food chain and can kill anything in its way.

8. Fossil Facts About Giganotosaurus: Giganotosaurus skeleton

This particular species of carnivorous dinosaur was found in Argentina during the Late Cretaceous period, which was almost 97 million years ago. 

Source by:  Wikipedia

In the early 1990s, a man named Rubén Dario Carolini, an amateur fossil hunter, discovered something quite extraordinary in the Neuquén Province of Patagonia—the giganotosaurus fossils. The largest carnivorous dinosaur, which he named Giganotosaurus, has comprised 70% of a complete skeleton to date.

The fossilized remains were scattered across a wide area, but thanks to the persistence and tenacity of the amateur fossil hunter, he was able to piece together most of the skeleton. It was an amazing discovery, one that has shed new light on the fascinating world of dinosaurs.

9. Giganotosaurus appeared 30 million years earlier than T. rex

Although its exact place in the fossil record is still debated, paleontologists believe this massive creature roamed the earth for only a brief time before becoming extinct around 65 million years ago.

If you have seen Jurassic World Dominion, you will know that T.Rex won the final victory. But in prehistoric times, could such a scenario occur? The answer is hard to say because Giga appeared 30 million years earlier than T.rex. Whether these two big guys can meet and compete is still an unsolved mystery.

10. Facts about Giganotosaurus: Did Giganotosaurus lay eggs?

In order to answer this question, it is first necessary to understand what medullary bone is. Medullary bone is a type of bone found in birds and dinosaurs that is filled with pores and spongy in texture. This layer of bone forms in the female of the species prior to laying eggs and is rich in extra calcium, which helps to form the eggshells.

There is evidence that all dinosaurs were egg-layers, and that many of them built nests. This suggests that nest-building was a common trait among dinosaurs. This meat-eating dinosaur is no exception.

11. Facts about Giganotosaurus: What color was Giganotosaurus?

Giganotosaurus was greyish-brown in color with a reddish-brown underbelly.

Those of you who have seen Jurassic Park 3 will remember that Giganotosaurus had lightning bolt-like stripes across its back. While it is speculated that the stripes may have been more commonly seen in other dinosaurs, there is no conclusive evidence for these claims.

However, interestingly, the red coloration on Giganotosaurus’ underbelly may be an indicator of poison glands.

12. Facts about Giganotosaurus: How fast could Giganotosaurus run?

A new study has found that it could run at a top speed of up to 31.3 mph. Despite its size, Giganotosaurus was agile and could make quick turns thanks to its tail. It was bipedal and had a long, thin tail that helped it maintain balance.

That’s all the facts about giganotosaurus. Hope those facts for kids will be useful when you want to develop your pint-size paleontologist.
