Giganotosaurus Vs tyrannosaurus rex -15 Amazing Differences (Sizes & Fights)

Tyrannosaurus Rex and Giantotosaurus were two of the biggest animals to ever inhabit the earth.

These animals were once the largest reptiles in the Americas, but they never got the opportunity to meet in person because the giganotosaurus was around 30 million years before the t-rex.

This raises the question of who would prevail in a fight in the Jurassic World context.

Compared to the giganotosaurus Vs tyrannosaurus rex size, the Giganotosaurus was larger and heavier. This lizard weighed over 14 tons and reached a maximum length of 46 feet. In addition, it was much stronger and faster than the T-Rex, with top speeds of 31 miles per hour. But the t-rex’s brain was larger and its bite was more powerful. The “king of dinosaurs” would probably prevail in the battle despite its little size.

The following table compares and contrasts the sizes of the Giganotosaurus Vs tyrannosaurus rex:

Characteristics	Giganotosaurus	T-Rex

*Science and research papers, journals, nature magazines, almanacs, and other official sources provided the data in the table. Some of these numbers are estimations due to a lack of research or data. The top weight (in pounds) stated for each species was multiplied by the top speed to determine the strike forces.

15 Differences Between Giganotosaurus Vs Tyrannosaurus rex

1. Size 

In combat sports, the first thing to look for when comparing fighters is their size, which frequently indicates the likelihood of winning the fight.

There are all the chances in favor of the giganotosaurus over the t-rex. At 44 to 46 feet in length, the giganotosaurus was really larger than the t-rex.

This reptile was tall in addition to being long. Archaeologists estimate that the giganotosaurus may have reached a height of eighteen feet.

Since the T-rex is known as the “king of dinosaurs,” it was by no means small. But it only reached a maximum height of 12 feet and a length of 36 to 40 feet.

The giganotosaurus would have an advantage in combat because of this distinction.

2. Weight 

Although determining the giganotosaurus and t-rex’s size from skeletal evidence was simple, determining their weight is a little more difficult.

It is generally agreed upon that the giganotosaurus was larger and heavier than the t-rex, with the largest individuals weighing between 10 and 14 tons.

The average weight of a T-rex dinosaur was between 5.5 and 8 tons, making them roughly two times lighter.

Though the estimated weight of the t-rex was validated by multiple studies, the giganotosaurus was not.

Actually, archaeologists have not yet discovered this giant’s entire skeleton, and it is difficult to rebuild its muscles without one.

This led to arguments, with some specialists arguing that this reptile had a slimmer body and a lower bulk, even if the giganotosaurus was larger.

Some people even think that the real weight was closer to 7 or 8 tons, which is what the t-rex weighed.

3. Locomotion Type

The giganotosaurus and t-rex shared a similar mode of locomotion. Both dinosaurs were members of the theropods, a kind of upright walking reptiles.

Actually, the giganotosaurus and tyrannosaurus rex looked a lot alike.

Both dinosaurs possessed stocky bodies and powerful legs, even though some people think the giganotosaurus was smaller than the t-rex.

In both species, the front limbs were short yet strong. They may have served as weapons, according to some scientists, however their exact function is still unknown.

Because the giganotosaurus’s front limbs have three digits instead of the t-rex’s two, this is one way that the two species differ from one another.

4. Footprint Size

The shape of the two species’ hind feet, and thus the shape of their footprints, is another resemblance.

The t-rex and giganotosaurus both have powerful hind limbs that culminated in bird-like, three-toed legs.

Interestingly, however, the king of dinosaurs had bigger feet than the giganotosaurus, even though the t-rex was smaller.

T-rex footprints range in length from roughly 2.5 to 2.6 feet, according to field data.

In the meantime, theropod dinosaur footprint measurements in South America, the home of the giganotosaurus, showed that southern hemisphere dinosaurs left footprints that ranged in length from 1.67 to 2.13 feet.

5. Speed 

Compared to giganotosaurus Vs tyrannosaurus rex, Giganotosaurus were larger and most likely heavier. Although their exact body mass has not yet been determined, it is evident that they were swift.

These giants were apparently capable of sprinting at a little over 31 miles per hour. At only around 12 miles per hour, this is more than twice the speed of a t-rex.

6. Skull Size

It is not surprising that the giganotosaurus had a larger head than the t-rex given the size gap between these two dinosaur species. The skull of this enormous reptile measured almost 5.5 feet in length.

The startling thing is how little it differs in size from the about five-foot-long t-rex skull.

It can be difficult to estimate the true size and intelligence of dinosaurs’ brains because they were extinct millions of years ago.

However, most researchers believe that t-rex were really more intelligent than giganotosaurus because of the size of their skulls and ideas that show giganotosaurus had a small brain.

7. Teeth Length

The long, pointed canine teeth of mammals, which make up the majority of terrestrial carnivores still in existence today, make them easy to identify.

But like crocodiles and other reptiles, dinosaurs were enormous lizards with a distinct kind of denture. However, this does not imply that they lacked long or sharp teeth.

The giganotosaurus actually possessed about 76 teeth, all of which were conical in shape and had serrated edges like steak knives. The dinosaur could readily pull flesh from bones thanks to these edges. Furthermore, their strong jaws allowed them to crush bone. Their teeth were actually almost eight inches long.

Compared to the giganotosaurus Vs tyrannosaurus rex were two of the most dreaded apex predators on the planet. s, the T-rex had a smaller skull and shorter jaws. These dinosaurs possessed about 60 strong teeth with strengthened ridges and a slight curvature. The t-rex’s six-inch-long teeth possessed serrated edges, just like the giganotosaurus.

8. Bite Force

As previously mentioned, the t-rex’s strong teeth were designed to crush bones easily. Nonetheless, their jaws were probably capable of exerting an amazing bite force since their teeth were so strong.

The tyrannosaurus rex had the strongest biting force, up to 48,505 N, according to a study comparing the bite strengths of many prehistoric dinosaur species.

It was never possible to quantify the giganotosaurus’s real bite force.

However, researchers discovered that the giganotosaurus was closely related to the Carcharodontosaurus saharicus, and the same study that was previously cited calculated the dinosaur’s biting force.

We may say that giganotosaurus was able to bite up to 25,449 N if the two species, which were similar in size, had equivalent bite forces.

Because of this, the t-rex is roughly twice as strong as the giganotosaurus.

9. Strike Force

A fighter’s attack power is another essential weapon in a battle that helps them defeat their opponent.

The giganotosaurus could easily defeat a t-rex based just on strike force. This dinosaur might have created an impact force of up to 868,000 pounds per foot-second because of its larger body mass and faster speed.

The t-rex was much weaker in contrast. The king of dinosaurs could only generate an impact force of roughly 186,000 pounds per foot-second while running up to 12 miles per hour and weighing up to eight tons.

The giganotosaurus was therefore roughly 4.6 times more powerful than the t-rex.

10. Classification 

The giganotosaurus Vs tyrannosaurus rex were two of the most dreaded apex predators on the planet. members of the same biological kingdom, phylum, class, superorder, order, and suborder, and they are both extinct reptiles.

This is where the similarities stop, though, because the two dinosaur species are from distinct families.

The Carcharodontosauridae family, Allosauroidea superfamily, and Carnosauria infraorder all included Giganotosaurus. The Carcharodontosaurus saharicus dinosaur, which is indigenous to Africa, belongs to this family.

The sole species in its genus and subfamily is Giganotosaurus carolinii, also known as giganotosaurus.

Tyrannosaurus rex, or t-rex, was long thought to be the sole member of its genus and subfamily, Tyrannosaurus saurinae.

However, Tyrannosaurus regina and Tyrannosaurus imperator, two other tyrannosaurus species, seem to have descended from the same progenitor prior to the tyrannosaurus rex.

A study claims that Tyrannosaurus imperator is the ancestor of the t-rex, which may have briefly coexisted with the other two species.

11. Geographic Range

Although both the The  giganotosaurus Vs tyrannosaurus rex were two of the most dreaded apex predators on the planet. were endemic to the Americas, they each lived in a different hemisphere.

From what is now Canada to Mexico, the T-rex roamed the regions that make up North America.

South America was home to the Giganotosaurus. Although Argentina was its main range, it also lived in portions of Chile and Peru.

12. Habitat

 

Archaeologists believe that giganotosaurus primarily lived in plains and woods based on the locations of fossils.

There is little evidence of giganotosaurus, though, and it’s possible that the reptile existed in more varied environments.

Compared to giganotosaurus, T. rex fossils are more numerous and demonstrate their diverse habitats. The majority of sub-tropical and semi-arid environments, including plains and coastal regions, were home to these dinosaurs.

13. Behavior

The  giganotosaurus Vs tyrannosaurus rex were two of the most dreaded apex predators on the planet. Maybe this explains why people believe they were lonesome and violent.

However, there is evidence to support the idea that both species were sociable creatures that lived and occasionally hunted in packs.

According to scientists, the t-rex may have been far more gentle than popular culture would have us assume because it is unclear if it was primarily a predator or a scavenger.

14. Diet

Both the giganotosaurus and the t-rex were predators that consumed herbivore dinosaurs as well as a wide range of other extinct creatures. Both dinosaurs were probably apex predators in their respective geographic ranges because of their size.

giganotosaurus Vs tyrannosaurus rex were thought to be scavengers in addition to hunters and killers of their own prey.

15. Geological Period

The  giganotosaurus Vs tyrannosaurus rex shared a common geological epoch, much like the spinosaurus. This does not imply, however, that they happened simultaneously.

Between 120 and 96 million years ago, during the Early Cretaceous period (around the same time as Spinosaurus), Giganotosaurus thrived.

They went extinct about 30 million years before the t-rex evolved, which occurred between 90 and 66 million years ago.

Who Would Win A Fight?

There was no possibility that a t-rex and a giganotosaurus would encounter each other in the wild. The former went extinct long before the first t-rex was born, and they also lived in various parts of the earth.

However, the t-rex would probably prevail if scientists were to bring dinosaurs back to life and place them in the same environment.

Even though the t-rex was smaller, lighter, and moved more slowly, its jaws were extremely strong and could have killed its opponent with a single, well-placed bite.

Furthermore, compared to giganotosaurus, the larger brain volume indicates a higher level of intellect. In comparison to its adversary, this would have allowed the t-rex to develop superior ambush and defense tactics.
