The Argentinosaurus was one of the enormous dinosaurs ever to roam the earth. Weighing around 100 tons and measuring up to 115 feet long, this massive creature was a sight to behold!

In this article, we'll take a closer look at this prehistoric behemoth, including what scientists believe its diet may have consisted of and how it might have moved around on land.

The Argentinosaurus is one of the largest land animals ever discovered.

It is thought to have weighed over 70 tonnes and measured over 30 meters in length.

The Argentinosaurus lived in what is now South America during the late Cretaceous period, around 90 million years ago.

Although its exact habitat is unknown, it is thought to have lived in a semi-arid environment, such as savanna or desert.

The Argentinosaurus was a herbivore; its teeth suggest feeding on low-lying plants.

Four thick legs supported its body, and its tail was long and heavy, providing balance.

The Argentinosaurus had a small head with slits for eyes, and its nose ended in a beak-like structure.

It is believed to have been covered in scaly skin, and some evidence suggests that it may have had armor plating along its back.

The Argentinosaurus was a massive creature, and its size has helped to make it one of the most famous dinosaurs among fossil hunters and collectors.


Scientists believe Argentinosaurus was an herbivore based on its teeth and jaw structure.

Its teeth were worn down from chewing thorny vegetation, and its jaw was adapted for grinding food.

Scientists believe it may have grazed on low-lying plants, such as ferns and cycads, or it may have been a browser, meaning it ate leaves and branches from taller trees.

Given its size, the Argentinosaurus would have needed to consume a large amount of food daily to maintain its energy levels.

Some evidence suggests that this massive dinosaur may also have eaten fruits and nuts from time to time.

Based on fossil evidence, scientists believe Argentinosaurus stripped leaves from plants with its beak-like mouth before grinding them up with its teeth.

This colossal dinosaur probably spent most of its time eating, as it would have needed to consume large amounts of vegetation to sustain its massive body.

While we can only speculate about what Argentinosaurus ate, we can be sure that this towering dinosaur was a gentle giant. His diet helped it to thrive in the Late Cretaceous period.


The Argentinosaurus is believed to have reproduced through a process known as oviparity, which is the laying of eggs.

Scientists believe that the eggs were around 2 feet in diameter and that the mother would have guarded them fiercely until they hatched.

It's possible that the young Argentinosaurus would have been cared for by their parents for an extended period after hatching, as is common among many large animal species today.

The lifespan of the Argentinosaurus is unknown, but scientists believe that this massive creature could have lived for over 100 years.

Due to its size, the Argentinosaurus would have been less vulnerable to predators and diseases than smaller dinosaurs.

In addition, its enormous body would have allowed it to store more fat, which would have provided it with energy during times of food scarcity.

While we don't know precisely how long the Argentinosaurus lived, we do know that this impressive dinosaur was a force to be reckoned with during its time on earth.



The Argentinosaurus was native to South America, and its remains have been found in modern-day Patagonia.

The Argentinosaurus was a titanosaur family member, characterized by their long necks and tails, stocky build, and small heads.

These dinosaurs were quadrupeds, meaning that they walked on four legs, and they are thought to have been amongst the last of the non-avian dinosaurs to go extinct.

Given its size and weight, it is likely that the Argentinosaurus was a slow-moving creature that spent most of its time grazing on vegetation.

However, its size would also have made it a target for predators, so it would have needed to be able to defend itself.

Due to its impressive size, the Argentinosaurus is one of the most well-known dinosaurs, and it continues to capture the public's imagination even today.

The Argentinosaurus is a genus of titanosaurs from the Late Cretaceous Period.

The first bones of this gigantic creature were discovered in Argentina in 1987, and since then, a partial skeleton has been assembled from scattered remains.

The complete specimens belong to a species known as A. huinculensis, which weighed an estimated 70-100 tons and reached lengths of 30-35 meters.

Given its size, the Argentinosaurus was the largest land animal ever, and its discovery has shed new light on the upper limits of dinosaur growth.

The bones of this titanosaur have also helped scientists better understand these massive creatures' evolutionary history.

Other Interesting Facts

  • With a weight of around 100 tons, the Argentinosaurus was one of the largest land animals to roam the earth.
  • Its name means "silver lizard" in Latin.
  • The Argentinosaurus is a genus of titanosaurs, a type of Sauropod dinosaur.
  • The first bones of this creature were discovered in Argentina in 1987.
  • Scientists believe that the diet of the Argentinosaurus may have consisted of primarily small plants and trees.
  • Given its size, the Argentinosaurus likely had few natural predators.
  • Some scientists believe that the Argentinosaurus may have been able to move around on land by using its large tail as a counterbalance.
  • The discovery of the Argentinosaurus has helped scientists learn more about the upper limits of dinosaur growth.
  • The bones of this titanosaur have also provided valuable insight into the evolutionary history of dinosaurs.

Final Thoughts

With its massive size and interesting facts, the Argentinosaurus is a creature that fascinates scientists and laypeople alike.

Scientists have learned a lot about the Argentinosaurus by studying its bones. For example, they have determined that this massive creature may have primarily eaten small plants and trees.

In addition, its large size would have made it less vulnerable to predators and diseases than other dinosaurs. The Argentinosaurus is a fascinating creature that provides an intriguing look into the prehistoric world.
