The 10 largest prehistoric animals that lived on Earth

During prehistoric times, gigantism was a rather common thing. Indeed, practically all the animals were much bigger than the norm: the “Titanoboa,” the snake’s ancestor, which measured nearly 13 meters long, or the turtle, called “Carbonemys,” which was so large. that she reigned as a formidable predator.

Not to mention the Paraceratherium, the largest land mammal that has ever existed with its 9 meters long and its incredible weight of 20 tons. Make yourself comfortable because here are the 10 largest prehistoric animals of each species that lived on Earth.

The Gigantopithecus: a giant monkey

Did you think “King Kong” was a legend? So, think again! Filmmakers were certainly inspired by an animal that has truly existed for millions of years. Her name? The “Gigantopithecus! “.

It is by far the largest hominid to exist on earth. And for a good reason! He could stand up to 3 meters tall and weigh 500 kg. Today’s largest gorilla would look pale in front of the “Gigantopithecus.”

  • A gigantic vegetarian monkey

This oversized monkey was, nevertheless, vegetarian, according to scientists. So it was not a predator. Only, we can imagine that he could behave very aggressively in times of danger. And in that case, it was better to keep your distance.

Fortunately for us, this monstrous ape, ancestor of the orangutan, disappeared 100,000 years ago, during the last ice age. So, not having been able to adapt to his new surroundings, “King Kong” died, probably of hunger.

Also, some cryptozoologists believe that the “Gigantopithecus” is still alive. Indeed, they believe in the existence of the Yeti, and the Bigfoot considered legendary. These creatures would be specimens of the “Gigantopithecus.” But rest assured, this is certainly just a myth!

The Carbonemys.

Sixty million years ago, a creature known as the “Carbonemys” lived on earth. It is a giant freshwater turtle that averaged 2.50 meters in length and had overpowered jaws. For a turtle, that’s huge!

Its 1.80-meter shell was extremely long and strong, which made this turtle, no doubt, formidable for the crocodiles that it could make its lunch!

This turtle is really terrifying! By way of comparison, the current gigantic turtle, called “Lute,” does not exceed 2 meters in length.

The largest turtle that ever lived on earth.

Thus, the one called “Carbonemys” was vastly larger, but above all, fiercer than any current turtle. If the “Carbonemys” was so large, it was probably because the climate was warmer than it is today.

Because of this, this prehistoric turtle was more likely to develop a titanic size, much like most prehistoric animals.

Although scientists do not know why this turtle went extinct, they do know, nonetheless, that it had such an appetite that it was difficult for several specimens to live near each other, which probably caused their loss.

Here, now, is the largest land mammal that ever existed. Its name is “Paraceratherium.” He lived about 34 million years ago. Today, it fascinates scientists with its oversized size.

Indeed, this giant was no less than 9 meters long and had a length at the withers of 5.25 meters. Thus, its weight could easily reach 20 tons. Isn’t that amazing? For comparison, the current largest rhino, the white rhino, is 1.70 meters tall at the withers and weighs 2.3 meters.

  • A gigantic ancient mammal.

Today’s largest mammal, the African elephant, stands 3.3 meters tall at the withers and weighs 5.5 tonnes. We have to believe that the “Paraceratherium” was far larger than any mammal!

In fact, this gigantic animal is a kind of rhinoceros, without horn, but much more slender.

He had long and thinner legs than his cousin and an equally slender neck. Obviously, he was also much bigger and much taller. Now this rhino has completely disappeared from the planet’s surface and has been for millions of years.

There was a time when giants ruled the earth. And we are not talking about the dinosaurs that made the ground tremble with their heavy steps, but rather the insects, and more precisely, the remarkable “Meganeuropsis Permian.”

This is one of the largest insects to have lived on Earth some 300 million years ago. This dragonfly-like creature was 43 cm long and had a wingspan of up to 71 cm.

C’est véritablement énorme ! D’ailleurs, le plus grand insecte actuel est un phasme et il ne mesure pas plus de 56 cm, antennes comprises.

C’est dire à quel point le « Meganeuropsis Permiana » était titanesque pour un insecte, d’autant plus qu’il pouvait voler.

Par ailleurs, sa taille hors norme est probablement due à la concentration de l’oxygène dans l’air qui a atteint, à l’époque, 35% contre 21% aujourd’hui, ce qui a favorisé le développement d’insectes géants. Heureusement que ce n’est plus le cas, puisque le « Meganeuropsis Permiana » a disparu. Il aurait créé, sinon, une véritable frayeur.
